Is a combination between grid /trend/trend reversal and semi martingale (not martingale because is very risque) . The DD is calculated on maximum 10 % .You must have ECN account,or my profit will be loss on your account because of spread (My broker have 0-1 spread and 0.05 comission /0.01 trade) .I can also manage your accounts directly on my VPS if your account is not ECN /Send me a private message.
