Journal stats that changed how I trade, and ones that didn't

[FXS London Scalper]

I track a lot of numbers in my journal. Looking back over the last year, only a few of them actually led to changes. Here's my honest list.

Changed something:

• R by hour of day. Showed that trades after 11:00 London were negative, so I stopped trading after 11:00 unless there's US data.
• MAE of winners. Showed my stops were too tight on GBPUSD, so I widened them by 1.5 pips.
• Win rate after two consecutive losses. Dropped sharply, which led to my two-loss daily stop.

Interesting but no change:

• Day of week. Small differences, nothing consistent.
• Trade duration. Useful once, to set a time stop, but not since.
• Average R per month. Too noisy to act on.

Never useful:

• Total pips. Meaningless with different stop sizes.
• Maximum consecutive wins.

My lesson is that a journal should answer specific questions. Collecting everything makes it harder to see the few numbers that matter.
