What to check, month by month:
- In months when you were behind target going into the last week, did trade count in that week rise?
- What was the win rate and average R of those extra trades?
- Did any month that would have ended slightly positive end negative?
- In months where you hit the target early, did trade quality drop because "it's a free month now"?
An alternative is process targets instead of results targets: rule breaks per week, share of A-quality trades, execution errors. These are under your control, and improving them tends to improve results without the end-of-month pressure.
Does anyone still use money or R targets? How do you stop them from changing how you trade?
