nice ea dirk.
I wrote a similar ea that employs hedging+grid+martingale strategy before, trades cable(GBP/USD), offers 6-12% pm, uses 0.01 lot size, 50 pips grid size, can sustain up to 7-9 levels before margin call (very similar like yours, judging by the history). My ea blew up the account in the back test if the trend is heading only one direction. Eventually I gave up the ea and look for some other better strategies.
I've read some interesting topics about traders use hedging+grid+martingale still able to beat the market without blowing up the accounts for couple of years. It requires constant monitoring during volatile market, turn it off before major news release or trade manually if the market is against you. I guess you are an experienced trader and shouldn't be a problem for you.
it always got me curious about how hedging+grid+martingale strategy protect the profit, does your ea offer certain protection if your grid goes up to certain level?
