My role in the forex grid trading expert advisors https://fxzig.com/blog/grid-trade-expert-advisors was to research forex expert advisors. Researching was done in a very professional way .It is kind of science. Researching was done in several phases. The first phase was the backtest. In that phase my goal was to watch for unwanted behaviour of the forex ea and make the required changes that will make the system stronger. In the forex market there are too many quotes, and the systems are executed at every quote so the other part of my job was to improve the performance.
