Normalized Candlesticks (stochastic candles)

This indicator is a normalized price representation made with candlesticks. The dynamic scale between 0 and 100% is calculated upon the last X periods (50 periods in the code, you can change it at will).  It can be used to detect price exhaustion in a trend of continuation if the candlesticks remains above the 50% level.

Another utility is the use of the different levels that could be changed to Fibonacci levels for examples (23.6% 38.2% etc.) and detect rebounds of breakout of these levels.

PRT 10.3 compatible only because of the use of the DRAWCANDLE function.

Coded by request on the French forum (french video that explain the development process of the normalized candlesticks).
