Thanks for posting. It is threads of this type that are the most valuable to all traders. It takes a humble spirit to post failures, so you are well on the way to success.
May I respectfully suggest that you take a break and re-analyze your trading rules because they seem to not make sense to me. Looking at GBPUSD, the trend is short on monthly, weekly and daily. This is an unusual occurrence to have all 3 timeframes in agreement, and although the price action is close to the bottom of a channel that has been developing since May, it doesn’t mean it is higher probability to go long against the trend. Did you use a confirmation indicator and if so what was it?
Firstly, it is my belief that statistical back testing has shown that trend following has a higher percentage chance of being right than wrong, and trend reversal trading has a lower chance of being right than wrong. I have not proved this myself by personally backtesting, but I take it as a generally accepted fact.
Secondly, from your previous line “After recovering 45% of my loss since last post”, either you have had a few ten baggers, or you are still using a high percentage of your bank for each trade (your risk per trade, or number of concurrent trades). What % of bank are you risking at any point in time? How much of your bank is at risk with concurrent open trades?
I hope these questions are constructive and cause you to reassess whether your trading rules are giving you a fair chance of approaching a positive edge over time.
