jlpi - a couple of questions for you:

1) What is the definition of an anti-martingale strategy? Where do enter/exit and with how many lots.

2) I quite agree that martingale will blow-out when the trend is against you. So what methodology do you use for detecting the trend at an earlier-enough point so that you stop entering the market/take the loss and trade the other way?

3) MM is the key or the failing - imagine a simple situation of doubling position size every 10 pips and you are working on a risk reward of 2:1 - you only need a "recovery" of 20 pips to make the profit. trouble is at 10pip gap you will blow a $10,000 account on cable after 80 pips move against. So what do you do - widen the gap - to survive a drop of 500pips (and it happens!) you need a pip gap of about 70 so your target should be 140.

To trade a 500 pipsmove and then retrace 140 to make your profit could take days/weeks - have you as a trader got the stomach to see you account sitting at minus 90% while the rocovery takes place. I know I haven't! Has anyone ever tried running these systems on a big pip gap? No - the reason being that if you happen to catch the trend and you only have 1 lot open you make $140pips on an account and feel cheated 'cos you have only 1 position on. But its still 1.4% account profit which is very healthy if you can achieve it every day.

I have tried many combinations but they have all blown up - currently testing one with a different approach - vary/widen the pip gaps and target values the more the market moves against the position - you can certainly survive longer but I am not sure that it will prove to be profitable.

Anyway, back to your trend theory - what do you use to detect? How do you trade?
