Multicurrency hedge example EA (overlay hedge) - expert pour MetaTrader 4

The Expert Advisor looks for correlations of the Market Watch list symbols, calculates Average True Range ratios for every hedging combination and assigns different magic numbers for them. Then the subsequent operations can be easily carried out with the prepared data. For precision, statistics like correlation and ATR ratio are recalculated every day.

The Expert Advisor can work with all the currency pairs from the Market Watch list on a single chart simultaneously, as well as it does not depend on the incoming ticks from particular symbol. For the purpose of showing the principle of action, hedging technique was implemented based on overlay chart indicator presented here https://www.mql5.com/en/code/7933.
