TTP PNR filterPNR filter uses the "percentile nearest rank" method to produce signals from any source including oscillator indicators and price bars.
Features:
* Length - how many candles back in time to use for calculating PNR
* % low and high - what range of the spread of values captured will form the PNR band. Use 99&100 to create a band on the 1% highest percentile or 0&1 to create a band in the lowest percentile. It accepts float numbers so you can find very rare occurrences.
* src - by default it will use the close price but PNR filter can be used with any source. It's particularly useful when working with oscillators like RSI, MACD, ADX, etc.
* Signal direction - The indicator will print 1 when the selected conditions are met. Once the PNR band is plotted you can chose from cross over, cross under, above and below conditions to trigger a signal.
* Signal source - the band consists in a % low and % high, this option allows you to pick which band will be used with the "signal direction" parameter.
Example configuration:
1) Select 200 as the length
2) Select % low 0 and % high 1
3) Add RSI to the chart and select it as the source parameter
4) Select signal direction cross over
5) Select signal source % high which corresponds to the 1% band
In this setup you are finding values of RSI that in the past 200 candles have been that low only 1% of the time. With each new candle the calculation window will move as well leaving the oldest candle out.
