Range ( Adjustable ) HLLSfor range of the price ( Adjustable )
This indicator shows you in what price range it may move.
This indicator is adjustable. You must set your installation to the past of its chart. (depends on timeframe)
Pay attention to adapt it in different time frames and with your strategy.
The function of this indicator is simple.
Based on the first factor (the number of previous candles), you can adjust average range channel with the second factor for height of the channel.
Bands and Channels
MA Band Distance Monitor'MA Band Distance Monitor' indicator is a simple tool for traders who rely on moving averages to make trading decisions. This indicator plots two moving averages of your choice (you can select the type of the moving average), and fills the space between them, creating a "band".
The indicator also generates a table that displays the current price distance from both the fast and slow moving averages, as well as the average of the two. This allows you to quickly assess the strength of the trend and potential entry or exit points.
In addition, the table also shows the average price distance from one to another MA and also the current distance between them, allowing you to compare the current price action to the historical average. This information can help you identify potential trend reversals and assess the overall health of the market.
*** Slow length input must be greater than fast length input, otherwise indicator will produce faulty results
Waddah Attar Explosion with TDI First of all, a big shoutout to @shayankm, @LazyBear, @Bromley, @Goldminds and @LuxAlgo, the ones that made this script possible.
This is a version of Waddah Attar Explosion with Traders Dynamic Index.
WAE provides volume and volatility information. Also, WAE calculation was changed to a full-on MACD, to provide the momentum: the idea is to "assess" which MACD bars have significant momentum (i.e. crossover the Explosion Line)
TDI provides momentum, divergences as well as overbought and oversold areas. There is also a RSI on a different timeframe, for convergence.
Almost everything is editable:
- All moving averages are customizable, including the TRAMA, from @LuxAlgo
Waddah Attar Explosion_
- Three different crossing signals: histogram crossing contracting Explosion Line, expanding Explosion Line and ascending Explosion Line while both Bolling Bands are expanding; Explosion Line shows different color when expanding.
- Explosion line signals: Below DeadZone line and Exhaustion (highest value in a given lookback period). You can set a predefined EPL slope to filter out some noise.
- Deadzone signal : Deadzone squeeze ( lowst value in a given lookback period)
TDI:
- Overbought an Oversold signals. The OB and OS shapes have two colors, in order to display extreme signals on current timeframe or extreme signals on current and different time frame.
- Visual display of RSI outside the Bollinger Bands, and crossing of RSI Moving Average crossing of zero line.
I believe this combination is great for so many reasons!
Like the idea of TTM Squeeze? You can tune the Deadzone and Explosion lines to look for a volatility breakout
Like trading divergences or want to filter out extreme areas? The RSI is great for that
You like the using the MACD strategy but don't like the amount of false signals given? this WAE version filters some of them out.
If you are a Bollinger bands fan, you can customize both indicators to trade breakouts and/or mean reversion strategies, and filter out exhaustion of the bands expansion
This is my first publication, so give it a go and provide feedback if possible.
Gamification IndicatorDo you want your charts to look like a video game? Look no further! Would you rather be an alien racing through a lava tube, a surfer with great white sharks, an airplane flying through the clouds, or some other custom emoji setup of your choice? Traders can choose their own custom player emoji, trend indicator, obstacle emoji, and celestial emoji. This indicator is just for fun and is not intended to be used when making trading decisions. Enjoy!
This indicator also contains a live sun/moon emoji that should accurately reflect day/night and can give information about the current moon phases.
Shoutout to @citlacom for the public Moon Ephemeris and calculations. Building this indicator was a useful & fun introduction to financial astrology in Pinescript.
[blackcat] L1 Adaptive Choppiness IndexLevel: 1
Background
I have been working with choppiness index type indicator for long. However, there are several problems in tradintional one.
Function
One of the issue of conventional choppiness index is the noise or ripple is too obvious. I was wondering several ways to smooth it. As you may know, choppiness index is "one line" indicator. There is little room of freedom to change it too much. Then, I introduced adaptation algorithm to make "length" parameter adaptive, which can smooth choppiness index indicator to some degree. Meanwhile, I use ALMA to smooth the output again.
Remarks
I used my published dc_ta lib, which collects several dominant cycle algorithm from Elhers to make many indicator adaptive possible.
Feedbacks are appreciated.
Faytterro Bandswhat is Faytterro Bands?
it is a channel indicator like "Bollinger Bands".
what it does?
creates a channel using standard deviations and means. thus giving users an idea about the expensive and cheap zones. It uses a special weighted moving average different from standard bollinger bands, it also averages not only price but also deviations.
how it does it?
it uses this formulas:
how to use it?
its usage is the same as "bollinger band".
length represents the number of candles to be taken into account, source represents the source of those candles and stdev represents the coefficient of the standard deviation.
you can use it with other indicators:
Urika Confirmation IndicatorThe Urika Confirmation (UC) Indicator helps a user make a better decision about areas to enter the market for a trade. The indicated incorporates the highs and the lows of the price for a specific period. The information is depicted on this two-line indicator to show the direction of the price. The gap between the two lines is a cloud for determining the current position of the trade and staying in a trend.
The two lines in the indicator are a signal line and a slow line: the price is likely bullish if the signal line crosses above the slow line while likely bearish if the signal line crosses below the slow line. One can enter a trade if the price is above the cloud while the signal line crosses above the slow line, This is an indication that the commodity or stock is bullish and vice versa for bearish. One can avoid trading when the price is in the cloud.
UC Calculations:
The signal line is the average high and low of the prices using the fast-length input.
The slow length is the average of the past previous high and low prices using the slow-length input.
Ways to Use the UC Indicator:
It is convenient to use the indicator with Relative Strength Indicator. If the signal line crosses above the slow line -->> Bullish possibility (buy if RSI >= 55). It is a false buy/long signal if the cross occurs while RSI is below 55.
If the slow line crosses above the signal line -->> Bearish possibility (short if RSI <= 45). It is a false short signal if the cross occurs while RSI is above 45.
The indicator can be used at all timeframes. The user can use different settings to suit their way of trading.
The indicator uses the concept of the Ichimoku Indicator to provide users with
Bollinger Bands SignalsDescription:
This indicator works well in trendy markets on long runs and in mean-reverting markets, at almost any timeframe.
That said, higher timeframes are much preferred for their intrinsic ability to cut out noise. The example chart is in 3H TF.
Be mindful, the script shows somewhat erratic jigsaw-like behaviour during consolidation periods when the price
jumps up and down in indecision which way to go. Fortunately, there are scripts out there that detect such periods.
You can choose between 4 Moving Averages, Vidya being the default. Period, Deviation and Bands Width parameters
all of them affect the signal generation.
For the Pine Script coder this script is pretty obvious.
It uses a standard technical analysis indicator - Bollinger Bands - and appends it with a 'width' parameter and
a signal generation procedure.
The signal generation procedure is the heart of this script that keeps the script pumping signals.
The BB width is used as a filter.
You can use this procedure in your own scripts and it will continue generate signals according to your rules.
Trend crossierHello there!
I would like to share my script.
This is S/R levels indicator based on custom range for each step used for computing minimum/maximum of the range.
For example - we predefined step with 50 candles as one, after we have got the minimum and maximum of it - we come to the next 50 candles and do the same to it.
Finaly - we have got 20 lines for 10 steps.
After that - we set the ( SMA * mult) to have step between lines and if N of lines in range of step from eachother(if a+step > b and b+step > c ...) we call it a strong level.
It is not my idea(but my code), so I do not claim the uniqueness of this idea (the customer asked me to code it, but I also read about this method in open sources before).
The second thing - vectors of current trend direction on different timeframes.
For this task I took the same ranges, but ema () of each range. After first step it has an array with N values.
The next thing it does is take out "chain" one by one on each iteration. How does it do that? We take new AVG with neighbor values.
If we have 10 length at start - after iteration it becomes 9. So it repeats computing till length is 2.
After we have 2 points left - we can plot the line using indexes.
This way we can see the trend direction on different timeframes.
Feel free to use, change, put into another scripts. You can even never use it!
The right to publish this particular code was issued by the customer.
Have fun!
Global Net Liquidity - SPX Fair ValueThis is similar to the SPX Fair Value Bands indicator.
It currently only displays the fair value.
The original SPX Fair Value formula only includes the Fed balance sheet data.
This indicator incorporates the following central bank assets:
Fed
Japan
China
UK
ECB
This is currently experimental. Feel free to explore using different formula constants.
[blackcat] L3 Super Best Cost LineLevel: 3
Background
As suggested by @hedan1, he made a suggestion: this indicator can be further optimized to develop a dull line to filter the overall direction, and then use the sensitive line as a confirmation signal to enter.
One of my favourite tool to see fast trends which is simple but powerful. It runs under below market logic.
Function
With @hedan1's idea, the 1st thing i come up with is a two-layer structure: the inner sensitive part is the best cost line indicator, the outer layer is a supertrend indicator to control the overall trend direction.
Best cost line is a tool to model the people's mood and preference in the market. I define a typical price as wcx, when wcx is above the best cost line, which means traders are willing to use higher price to buy, then if you long, you are following the trend and make profit. On the other hand, if wcx is below the best cost line, which means traders are NOT willing to pursue higher price (maybe due to continous stop loss or sth other), then you should at least not long or if you are agressive in style, you may consider short.
That is it. Do you think it is simple and powerful enough?
Remarks
L: long entry, yellow
XL: close long, fuchsia
S: short entry, green
XS: close short, red
inner bullish: yellow color
inner bearish: fuchsia color
outer bullish: green color
outer bearish: red color
inner indicator : the best cost line
outer indicator : supertrend
also, i improved the display fucntinon remove some blur lines with linebr feature.
Feedbacks are appreciated.
Setup Max e Min Larry WilliansLarry Williams used this system to win the trading championship
Hello friends, I bring a script with a trading strategy to be used in futures such as Index, Forex and Commodities. Developed by famous trader Larry Williams.
In them we use two 3-period Simple Moving Averages (Arithmetic) (one with the high price, the other with the low price), and a 21-period Moving Average (Arithmetic) to determine the trend. This will form an average channel with the prices of the maximums and minimums of the last three candles.
Best time charts use the strategy: from 5 minutes to 60 minutes.
This strategy is quite simple. The 21 Moving Average will color according to the trend (Green for bullish, Red for bearish and Gray for transitions). The Script will signal the entry according to the trend by the colors of the candles and also by the signal:
When green, the buy will be on the crossing of the lower Moving Average crossing the candlestick, and the exit will be on the crossing of the candlestick on the next Upper Moving Average.
When red, the sell will be at the crossing of the Upper Moving Average crossing the candlestick, and the exit will be at the crossing of the candlestick on the next Lower Moving Average.
When the Script signals the candle with a purple X, it means that the trend is changing and the entire open operation must be closed.
This system has no Stop, so be careful when using it.
Na linguagem do autor:
Larry Williams usou esse sistema ganhar campeonato de trade
Olá amigos, trago um script com uma estratégia de trade pra ser usada em futuros como Índice, Forex e Commodities. Desenvolvido pelo famoso trader Larry Willians.
Neles usamos duas Médias Móveis Simples (Aritmética) de 3 períodos (uma com o preço da máxima, outra com o preço da mínima), e uma Média Móvel (Aritmética) de 21 períodos para determinar a tendência. Nisso vai formar uma canal de médias com os preços das máximas e mínimas dos últimos três candles.
Melhores tempos gráficos usar a estratégia: de 5 minutos até 60 minutos.
Essa estratégia é bem simples. A Média Móvel de 21 irá colorir de acordo com a tendência (Green pra alta, Red para baixa e Gray para transições). O Script irá sinalizar a entrada de acordo com a tendência pela cores dos candles e também pela sinalização:
Quando green, a compra será no cruzamento da Média Móvel inferior cruzando o candle, e a saida será no cruzamento do candle na Média Móvel Superior seguinte.
Quando red, a venda será no cruzamento da Média Móvel Superior cruzando o candle, e a saida será no cruzamento do candle na Média Móvel Inferior seguinte.
Quando o Script sinaliza o candle com X purple, significa que a tendência está em mudança e deve ser fechada toda a operação em aberto.
Este sistema não possui Stop, portando cuidado quanto a seu uso.
Triangular Trend Channel ATRTTCATR: Triangular Trend Channel ATR is a script to dynamically create a trend channel. It uses Moving Average & the Average True Range function to calculate support and resistance levels automatically.
The MA choices available are:
SMA = simple moving average
EMA = exponentially weighted moving average
RMA = moving average used in RSI
WMA = weighted moving average
VWMA = volume weighted moving average

SWMA = symmetrically weighted moving average
ALMA = Arnaud Legoux moving average
The default setting inputs are:
source = OHLC4
MA length = 20
MA signal = 10
ATR Multiply = 3
ALMA offset = 0.89
ALMA sigma = 5
Moving average type = VWMA
Level 1 ATR = 1.236
Level 2 ATR = 2.382
Level 3 ATR = 3.5
Level 4 ATR = 4.618
Level 5 ATR = 5.786
The default setting colors are:

R3 = green
R2 = orange
R1 = blue
pivot = white
(track pivot line = bullish is green, bearish is red)
S1 = purple
S2 = yellow
S3 = red
S4 = white
Bottom = gray

LNL Keltner CandlesLNL Keltner Candles
This indicator plots mean reversion (reversal) arrows with custom painted candles based on the price touch or close above or below keltner channel limits (upper & lower bands). This study was created primarily for swing trading & higher time frames such as daily and weekly. Lower time frames might result in more false signals.
Mean Reversal Arrows:
1. Reversal Arrow Up - If the price drops below the lower band extremes, reversal up is the trigger for a bullish mean reversion.
2. Reversal Arrow Down - Once the price reach the higher band extremes, reversal down is the trigger for a bearish mean reversion.
The Concept of Mean Reversion:
There are just two types of moves in any market: The market is either expanding from the mean or retracing back to the mean. These reversions & epxansions are happening across all types of markets. The goal of this study is to catch the powerful mean reversion from extremes back to the mean. Once the candles light up green / red, it is time to look for the reversal (purple) arrow which triggers the mean reversion setup. Mean reversion is not about catching the next big swing turn to new highs or lows. It is all about the base hits = the mean. So the target here is always the average price. The idea here is to catch the average market ebbs & flows, not the next home run.
What Do I Mean by Mean?
Mean is usually the average price from the last 20-30 bars. Basically something like a 20 MA or Keltner Channel or Bollinger Band midline are really good visual representators of the mean (average price).
Hope it helps.
XYZ Super Fibonacci Channel Cluster
Simple setups
Just input two different ema, X and Y.
Multiple = input Phi factor (ex: 0.38 , 0.618 , 1.618 , 3.14)
Usage
Grouping movements into channels to identify trend acceleration and deceleration
Example usability in the BTC/USD trading pair (timeframe = 1D) =>
Input Setups
Source = hlc3
Multiplier = 2
X Ema = 13
Y Ema = 21
How to identify acceleration and deceleration?
H_1 to H_2 => Bullish but no acceleration (because at same top level border).
H_2 to H_3 => Bullish with acceleration (go up to another top level border).
H_3 to H_4 / H_4 to H_5 => Bullish deceleration (because drop to another top level border).
L_1 to L_2 => Bearish signal (because fall below EMA-super and touch the bottom border of Super Channel).
L_2 to L_3 => Bearish acceleration (drop to another bottom level border).
L_3 to L_4 => Bearish deceleration (go up to another bottom level border).
Fibonacci Breakout Target LevelsFibonacci Extension
Fibonacci Extension is a powerful technical analysis tool that traders use to predict where the market might find support and resistance. It is based on the Fibonacci sequence and uses levels that are found by extending the 23.6%, 38.2%, 50%, 61.8%, and 100% Fibonacci ratios from a swing high or low. These levels can be used to find possible areas of support and resistance, and traders often use them to figure out when to get into or get out of a trade.
What does this indicator do?
This indicator gets five levels of the Fibonacci Extension and uses it for both the low and the high. The default lookback period is 10 days, and it checks for the highest and lowest price in that period. Then it calculates the extension levels and plots them, and it also adds a line that shows you the current breakout target levels.
How to use?
The primary use intended for this indicator is to be used to determine possible breakout target levels. Let's say you are trading a range and a breakout happens. You can use this indicator to determine possible take-profit zones and possible support and resistance zones.
Features:
Change the lookback period for the Fibonacci Extension levels.
Disable the Fibonacci Bands if you just want to see the FIB levels.
You can also change the 5 levels and add different Fibonacci numbers.
In this image, you can see how you can use this indicator to determine take-profit levels. The Fibonacci Extensions will determine potential support and resistance levels, which could be good places to exit your long or short positions.
VWAP 3x Session Reset- This VWAP aims to be used with futures and forex.
- The VWAP is reset at the beginning of each session.
- 3 different sessions can be specified.
- The lines are not drawn when there is no active session.
- The upper and lower bands with standard deviation 2 are also drawn.
Info: The time zone of the picture is Europe/Berlin
Momentum Deviation Bands [Loxx]Momentum Deviation Bands uses a variation of standard deviation. Instead of using price to calculate standard deviation, this uses momentum. This is another type of volatility that will be used in future indicators. This indicator serves more as an educational tool, but can also be used in trading.
You can read about the included moving averages here:

ER-Adaptive ATR Limit Channels w/ States [Loxx]As simple as it gets, channels based on high, low and ATR distances, Shows possible short term support / resistance or can be used as a take profit/stop-loss in some trading systems. It does this by comparing high/low values of price to multiplied by a multiple of ATR to determine when the trend changes. States are included to change the sensitivity to trend changes. 1 is very sensitive, 3 is least sensitive.
This uses Loxx's Expanded Source Types. You can read about them here:
What is ER Adaptive ATR?
Average True Range (ATR) is widely used indicator in many occasions for technical analysis . It is calculated as the RMA of true range. This version adds a "twist": it uses Perry Kaufman's Efficiency Ratio to calculate adaptive true range
Chebyshevs BandsThis script calculates upper and lower bands using Chebyshev's inequality formula.
The main pros.: the band doesn't depend on particular distribution. It fits to any type of random variables. Also it allows to calculate bands for instruments with extremely high volatility.
Cons.: formula provides a rough estimation in some special cases like lognormal distribution.
Fair value bands / quantifytools— Overview
Fair value bands, like other band tools, depict dynamic points in price where price behaviour is normal or abnormal, i.e. trading at/around mean (price at fair value) or deviating from mean (price outside fair value). Unlike constantly readjusting standard deviation based bands, fair value bands are designed to be smooth and constant, based on typical historical deviations. The script calculates pivots that take place above/below fair value basis and forms median deviation bands based on this information. These points are then multiplied up to 3, representing more extreme deviations.
By default, the script uses OHLC4 and SMA 20 as basis for the bands. Users can form their preferred fair value basis using following options:
Price source
- Standard OHLC values
- HL2 (High + low / 2)
- OHLC4 (Open + high + low + close / 4)
- HLC3 (High + low + close / 3)
- HLCC4 (High + low + close + close / 4)
Smoothing
- SMA
- EMA
- HMA
- RMA
- WMA
- VWMA
- Median
Once fair value basis is established, some additional customization options can be employed:
Trend mode
Direction based
Cross based
Trend modes affect fair value basis color that indicates trend direction. Direction based trend considers only the direction of the defined fair value basis, i.e. pointing up is considered an uptrend, vice versa for downtrend. Cross based trends activate when selected source (same options as price source) crosses fair value basis. These sources can be set individually for uptrend/downtrend cross conditions. By default, the script uses cross based trend mode with low and high as sources.
Cross based (downtrend not triggered) vs. direction based (downtrend triggered):
Threshold band
Threshold band is calculated using typical deviations when price is trading at fair value basis. In other words, a little bit of "wiggle room" is added around the mean based on expected deviation. This feature is useful for cross based trends, as it allows filtering insignificant crosses that are more likely just noise. By default, threshold band is calculated based on 1x median deviation from mean. Users can increase/decrease threshold band width via input menu for more/less noise filtering, e.g. 2x threshold band width would require price to cross wiggle room that is 2x wider than typical, 0x erases threshold band altogether.
Deviation bands
Width of deviation bands by default is based on 1x median deviations and can be increased/decreased in a similar manner to threshold bands.
Each combination of customization options produces varying behaviour in the bands. To measure the behaviour and finding fairest representation of fair and unfair value, some data is gathered.
— Fair value metrics
Space between each band is considered a lot, named +3, +2, +1, -1, -2, -3. For each lot, time spent and volume relative to volume moving average (SMA 20) is recorded each time price is trading in a given lot:
Depending on the asset, timeframe and chosen fair value basis, shape of the distributions vary. However, practically always time is distributed in a normal bell curve shape, being highest at lots +1 to -1, gradually decreasing the further price is from the mean. This is hardly surprising, but it allows accurately determining dynamic areas of normal and abnormal price behaviour (i.e. low risk area between +1 and -1, high risk area between +-2 to +-3). Volume on the other hand is typically distributed the other way around, being lowest at lots +1 to -1 and highest at +-2 to +-3. When time and volume are distributed like so, we can conclude that 1) price being outside fair value is a rare event and 2) the more price is outside fair value, the more anomaly behaviour in volume we tend to find.
Viewing metric calculations
Metric calculation highlights can be enabled from the input menu, resulting in a lot based coloring and visibility of each lot counter (time, cumulative relative volume and average relative volume) in data window:
— Alerts
Available alerts are the following:
Individual
- High crossing deviation band (bands +1 to +3 )
- Low crossing deviation band (bands -1 to -3 )
- Low at threshold band in an uptrend
- High at threshold band in a downtrend
- New uptrend
- New downtrend
Grouped
- New uptrend or downtrend
- Deviation band cross (+1 or -1)
- Deviation band cross (+2 or -2)
- Deviation band cross (+3 or -3)
— Practical guide
Example #1 : Risk on/risk off trend following
Ideal trend stays inside fair value and provides sufficient cool offs between the moves. When this is the case, fair value bands can be used for sensible entry/exit levels within the trend.
Example #2 : Mean reversions
When price shows exuberance into an extreme deviation, followed by a stall and signs of exhaustion (wicks), an opportunity for mean reversion emerges. The higher the deviation, the more volatility in the move, the more signalling of exhaustion, the better.
Example #3 : Tweaking bands for desired behaviour
The faster the length of fair value basis, the more momentum price needs to hit extreme deviation levels, as bands too are moving faster alongside price. Decreasing fair value basis length typically leads to more quick and aggressive deviations and less steady trends outside fair value.
Squeeze Range: Bollinger Bands / Keltner Channels [Whvntr]Presenting Squeeze Range: Bollinger Bands / Keltner Channels
TTMSqueeze method is a volatility and momentum indicator introduced by John Carter of Simpler Trading, which capitalizes on the tendency for price to break out strongly after consolidating in a tight trading range.
How did I make this indicator? The Bollinger Bands & Keltner Channels base scripts are from the standard indicators of their class in the Technicals section... I made this indicator first then noticed there were 3 others with a similar concept, but this differs in it's unique features and application of the TTMSqueeze strategy. This indicator plots the True Range of the Keltner Channel (Customizable in 'Bands Style" in the Inputs Menu) the instances the Bollinger Bands are within the range of the Keltner channel (the market just entered a squeeze).
Featuring: customizable Moving Averages
1. Exponential (Default for both BB & KC)
2. Simple
3. RMA (MA used in RSI )
Keltner channels have a multiplier of 2 & 3 on the Chart (3 being the outer).
How do I use this indicator? Once the teal dots are inside the solid red lines this would indicate that TTMperiod of low market volatility (the market is preparing itself for an explosive move up or down). Do some research and study how to use the TTMSqueeze method by John Carter. Disclaimer: not a guarantee of future favorable results.
Channel Lookback: Average Moving Price (CLAMP)How it works
This is a confirmation indicator based on moving averages. It compares the current price to a previous candle N periods ago, then smooths the result.
What makes this indicator novel is that it takes the smoothed curve and compares it to the previous value to see whether the slope is increasing or decreasing. Combined with a zero-cross baseline channel, we can compare the relative position of the curve, slope, or closing price to create entry signals. There are several hardcoded conditions that it checks, but this is easily changed.
Markets
The default values are best used on the SPY daily chart. With backtesting, it seemed to perform fairly well during the last year. It seems to be more accurate during choppy/bear markets, and very inaccurate during a trending market.
Eg, if you look at the period of growth that occurred during 2020, it basically said to keep shorting for months at a time. Not good. If you look at other markets (such as gold or uranium), it worked, but only if you inversed what the signal told you to do (eg going long when it says to go short). This is something you will have to test yourself, since every system and market is different. Please don't use this indicator by itself.
How to use
When combined with other indicators, this tells you whether to go long (green), go short (red), or no trade (gray). It is meant to be used as a confirmation indicator, so it will help verify other trade signals.
You can sometimes ignore the first grey circle and reuse the previous colored signal. There are a few markets (such as gold) I noticed this was helpful on; this will depend on your own trade rules and indicator system.
If you enable "simple mode" on the settings, it will draw only the final signal (long, short, no signal). I included this because it helps to reduce visual clutter.
