This EA you must know and understand how it works. In the hands of rookies it will blow your account. It use fibonacci numbers instead of lot multipliers. To limit the risk you must limit the martingale. At a value of 9 you trade in worst case with one lot. When the market move against you and the chart is leaving the grid a change EURUSD of one cent is 1000$ drawdown more. The EA will try to hedge the loosing grid but it start with 0.01 and this is not much to compensate 1 loosing lot. With a martingale set to 9 a balance of 10k would be save to start compounding you account. A martingale set to 8 would reduce you profit, but you can start with 5k. This balance is just for one currency pair and a start lot of 0.01 !!!
