Description

iTrend is a trend indicator.
This version for cTrader has been based on this indicator for MT5 by Nikolay Kositsin, which in turn is based on previous work by other authors:

https://www.mql5.com/es/code/2002

The indicator has two lines: bullish (green) and bearish (red).
If the bullish line is above the bearish line the price is trending upwards.
If the bearish line is above the bullish line the price is trending downwards.

The lines are calculated with an exponential moving average (EMA) as follows:

Bullish line = close - EMA
Bearish line = - (low + high - 2*EMA)
