This EA is based on placing both buy and sell orders using the grid trading principle, which is based on usage of the martingale rules.

It trading principle is that it opens a new order with an increased lot once a trade becomes unprofitable, and the more unprofitable the trade is, the more new orders are opened. This EA works in both directions, that is when it receives a signal, it can open the first trade, either buy or sell. This allows for a substantial mitigation of risks.

An important rule of working with such Expert Advisors is periodical profit withdrawal.

It is recommended to use the EA on the GBPUSD symbol, 1 minute timeframe.
