I dont think so. with proper money management we also not been guarantee will end in profit. We only try to minimize the cost and make our chances to open trade more. Since we run out our trading capital within 10 times entry, it means we got money management problem. let's say there is always 2% risk, so its mean we got 50 times to make wrong in the row to get margin call. I think we wont make loss in every trade 50 times in row right ?
