I did try all this. Waiting for good setups when all indicators scream you should buy, and when you buy your stop loss is hit. I tried all kinds of different Risk/Reward Ratios and all of them will result in a negative sloping equity curve over time. Trading with a stop loss is the very first cause of losing money in forex, it is actually a more contributing factor in losing then commission/spreads.
Right now, I'm using $2000 accounts to test this EA on live price action. Hopefully one day, I'll switch for $10000. Isn't a 7% monthly return worth the hustle?
Everyone has a stoploss, it's the margin call. You know this going into Martingale, and from others on this thread, but it seems you'll ignore the warning signs. A lot of trading is just like this too. That's why people let winning trades reverse, and hold losing trades all the way to sl.
You have to confront yourself psychologically about why these things happened. You can also view my account for reference. Calmed down and started doing the same thing in July. Average ~3% risk, only won 54% of 28 trades, but I closed up 20% for the month. I'm sure you can make 7% with just 1% risk if you put your mind to it.
