Hi Ct,
I am still looking into this. I spent much of last weekend trying to tweek a trading strategy to suit this scheme and run several variations through a simulator, but I am really struggling to find one that works sufficiently consistently with a fixed 2:1 RR.
I don't think that stops of less than 15-20 pips can work except on the shortest of TFs like e.g. 5m, but then the equivalent profit target of 30-40 pips is not achievable consistently enough to fit this project, which needs a 2:1 success rate on over 50% of trades.
Maybe it would help if one can also exit on a strategy reverse signal rather than on just limit or stop, but I dont know how to work that into the scaling formula...
I am looking now at either 1:1 RR on 15m TF (which looks promising but does not match the project rules) or a 3H TF using 2:1. I could have entered a first 3H trade in EURUSD last friday and won and then a second trade yesterday, both with a 25 pip SL and 50 TL but in both cases the SL was at a totally illogical and arbitrary and purely mathematical level, which is not a sensible way to trade - so that doesn't encourage me either yet!
I do not trade demos, I would rather use microlots on my No.2 account for these purposes so I am maybe a bit over-cautious here. But I will do it once I get my approach right. I won't bother you and others here on this thread until I am at least at level 3 as that is just wasting space.
I wish you every success with your own trades and am following them with great interest!
