The purpose of the Comparative Relative Strength Ratio indicator is to provide a way of looking at a relative strength ratio as a candle graph instead of only a closing price line, as well as to provide relative volume gradient coloration on the ratio-generated candles, and additionally to plot moving averages of the CRS ratio that can help display shifting trends in relative strength.
This is different from my Relative Volume Gradient Paintbars indicator, as well as my Comparison Chart with Relative Volume Gradient Paintbars indicator, in that the first looks at the charted symbol itself, the second looks at an alternate symbol, and this third indicator looks at a ratio between the charted symbol and the alternate symbol.
The idea behind this indicator is to provide additional means of evaluating relative strength, such as comparing the moving averages of the comparative relative strength ratio graph to the charted stock symbol's own MAs in order to gauge strength, comparing the price action of the ratio to that of the individual stock and its index, and comparing the volume gradient signal between the ratio, the stock, and the index.
The unique volume features allow comparing volume as a percent of the index volume, as well as stock's candle range as a percent of the range of the index. So when the volume as a percentage of the index's overall volume becomes high, this can be made to highlight the candles.
