The Expert Advisor is an advnaced version of Signals 3 MACD. The main difference is the auto optimization of basic parameters. Here you do no have to select CCI and Stochastic levels, MA periods and other indicator parameters. The EA optimizes parameters during trading. The number of auto optimization bars is set manually.

The trading system is based on crossing of three signal lines (with different parameters) of the MACD indicator. When all the lines are increasing, a buy order is opened (the opposite - sell order). The CCI indicator is required to avoid buying at the highest price but to buy when the price decreases a bit, but there is still an uptrend.

The EA is easily customizable and can be used on timeframes M5-H1. It can be used on the M1 timeframe as well, if the spread is very low. Recommended pairs are EURUSD, GBPUSD, USDCAD, USDJPY, EURGBP. The EA does not use risky trading strategies, it always sets stop loss which it can later transfer to a small profit.
