Kroko Trader EA is a trading system that uses William´s Alligator indicator as trend and trigger signals. Also, as a filter, ATR can be configured to trade only in certain volatility.
Takeprofit and Stoploss are calculated according to multiplier of ATR values, resulting in a dynamic stop function.
Optimized EA was on EURUSD, H1. But, it´s possible to optimize on other timeframes and currencies.
