What's the minimum account balance to start trading with this EA? Can it work on small accounts of less than $500? And can you tell us the lot size to start with based on a $1,000 account for instance? We can scale according to account equity afterwards.
For this, and most of other martingale based EA an absolute min. of $5000 running 0.01 lot is needed (the more the better)from my experience ! Adjusting your pipstep will also reduce risk (higher pipstep = less risk). Don't use too high multiplier (Lotexp), the default of 1.357 is fine to start off. With martingale EA's, BE SURE THAT ONE DAY YOUR ACCOUNT WILL BLOW UP. ! It's not a question of will it happen but a question of WHEN will it happen, so be carefull :-)
What I would do if I only had $500 for trading this EA. Open 5 different cent account of $100 (= 10.000 cent). Run on EACH account a different pair (pick non trending pairs) with 1 chart buy EA and another chart Sell EA. Use your preferrable pairs and time frames.
At the end of each week you will TAKE THE PROFITS of the equity, not balance (above $100) and put it on a side account. If EA is at loss that week, let it run until in profit and then also take profits off. Do this with the 5 different accounts, each week.
If at a given point, one accounts blows up, you will have most likely made already enough profits on your "side" accounts to start up a new one.
You also have to think that such EA's are not "set and forget". You have to keep an eye on it and when you see that one or the other account is coming into trouble, you have to take action BEFORE it blows up. You can close your positions, take the loss and start over or you can, like I do, take manual trades at major support/resistance, to help the EA a hand and try to close all at breakeven or small(er) loss. But as you can understand, you will not always have the chance to do that :-)
