Function Square WaveThis is a script to draw a square wave on the chart, with an indicator for current price. Markets undergoing Dow Jones or Wyckoff Accumulation/Distribution cycles tend to move in such waves, and if the period of the cycles are detected, a signal for accumulation/distribution phases can be created as an early warning. Useful inputs: - Average True Range as the wave height. - Assumed Wave period as the wave duration. I divided the current price wave by 2 to make the indicator more visually friendly. GLHF - DPT

Grid SystemThis script plots a a square composed of 8 equilateral triangles ("grid"). User can set the frequency of calculation/interval by adjusting the 't' parameter. Steps for calculating grid: 1. Find the highest high and lowest low for last 't' periods. 2. Calculate midpoint for prices during that interval (highest high + lowest low) / 2. 3. Center of the grid = {time , price midpoint}. Interpretation: Volatility : If price is volatile for a given period, the area of the grid will expand, since the top and bottom sides are based on the highest high and lowest low for the period. So as range for a given period increases, the grid's area increases. Support and resistance : The grid's center line often acts as the support / resistance line. Trend Following : The example chart shows Cognex (CGNX) price using an interval of t=365. When the stock's trend was bullish, the area of the grids became increasingly larger and the y-coordinate of each grid was greater than that of the previous grid.

[JRL] Murrey Math LinesMurrey Math Lines are support and resistance lines based on geometric mathematical formulas developed by T. H. Murrey. MM lines are a derivation of the observations of W.D. Gann. Murrey's geometry facilitate the use of Gann's theories in a somewhat easier application. According to Gann's theory, price tends to trend and retrace in 1/8th intervals. The most important MM line levels are the 0/8, 4/8 and 8/8 levels, which typically provide strong support and resistance points. The 3/8 and 5/8 levels represent the low and high of the typical trading range. When price is above the typical trading range, it is considered overbought, and when it is below it is considered oversold. The 2/8 and 6/8 levels provide strong pivot points. Some of the other Murrey Math indicators on TradingView use different formulas and therefore produce varying results. I've checked my indicator against MM indicators on other platforms and it is consistent with those indicators. This indicator also allows users to switch to alternative timeframes for analysis and it includes labels for the MM lines. If you have any suggestions or comments, please leave them below. Cheers!
