This is a scalping Expert Advisor for trading highly liquid currency pairs. The trading robot uses a unique strategy applying Envelopes as a filter. It is recommended to use a low spread broker and a VPS server. The Expert Advisor can be easily optimized on historical data. Also, I recommend trading during the Pacific session only.

Recommendations

Before running the EA on a real account, optimize input parameters for each currency pair. I recommend optimizing the following parameters on the last month using the quotes with the history quality of 99.9%:

1. ProfitClose – set the start to 0.5, step – to 0.5, finish – to 5;
2. EnvPeriod – set the start to 5, step – to 1, finish – to 9;
3. EnvMethod;
4. EnvPrice;
5. EnvUpperDeviation – set the start to 0.05, step – to 0.05, finish – to 0.8;
6. EnvLowerDeviation – set the start to 0.05, step – to 0.05, finish – to 0.8;
7. TimeStart;
8. TimeFinish.
