- Session: A (Asia), L (London before 12:00), LL (London after 12:00), N (New York).
- Spread at entry: tight, normal, wide. Wide means above 1.5 times your usual for that hour.
- State of mind: calm, rushed, frustrated. Recorded before the trade, not after.
- Whether "rushed" or "frustrated" trades do clearly worse than "calm" ones.
- Whether wide-spread entries are worse even when the trade works, which shows the cost directly.
- Which session is weakest. Most people know, but numbers make it harder to ignore.
Keep the tags fixed for the whole sample. Changing definitions halfway makes the comparison meaningless.
