Make screenshots of all your profitable trades (with your indicators on them), during the last 4 yeras, also all relevant time frames. Also all loosing trades.
Print everything out, take one month of and beginn: note down the circumstances, under which your trades were winner. Do the same with the looser trades. Write the rules of the winning trades on a sheet of paper, also the loosing ones on another sheet.
Now hammer this schemata into your brain-when everything is on your brain-hard-disk and your rules are on a cheet sheet start again trading, and only enter a trade when your winner rules are valid and ignore the failure signals.
