Well, I looked back at the bigger losing trades. I don't believe that the S/L settings have changed with v47; just that the settings have now become a user option, rather than just being coded in.
While some of the trades would have eventually become profitable with a larger S/L, others would just have stopped out at an even greater loss; overall, no gain with a greater S/L.
With this small number of trades, it is not conclusive to determine the ideal S/L settings; a couple of years at least of back-testing would be required; presumably what the FAPT Team have already done.
Sadly, my losing streak has returned. I now have two version running on demo accounts; one with the default settings on an FXCBS account. This is producing an overall loss; some days profitable, wiped out by the larger losses. As it is an ECN broker, the spreads are very low and consequently there are very many more trades per session than most FAPT users experience. I have a second version running; also an ECN account, but this time with ATC Brokers. This has the same settings as the FPA long-term test. Strangely, there are significantly fewer trades per day, although the spreads on the two demo accounts seem very similar if not identical. The account has not made the same losses as the other; a modest profit in fact. However, given small return, against the the potential for large losses, I cannot justify placing this on a live test account.
I wish I knew what was causing these discrepancies; some people reporting wild profits, other losses, most (presumably) using the same settings, known differences between brokers. All a bit random for me; certainly for an EA that I was considering for unsupervised overnight trading. I don't quite see the point of an EA that I have to monitor. Better off trading manually. Its a bit like an automatic washing machine where you have to manually add the soap, rinse and spin in case it ruins your clothes!:unhappy:
