Your trading journal is lying to you
Your trading journal is lying to you. Not because the numbers are wrong — because of which trades never make it in.
Be honest: the clean winner gets logged with screenshots and a victory lap. The 11am tilt trade you knew was wrong before you clicked? "I'll log it later."
Later never comes. Your journal is a highlight reel with a data problem.
Selection bias is fatal to the whole point
The trades you skip logging are precisely the ones holding the answer. You're running a study that excludes the disease.
Every Sunday review built on that journal inherits the bias. You study the trades that were easy to look at, conclude your process is mostly fine, and wonder why the account doesn't agree. The account has the full dataset. You don't.
Two fixes that worked for me
One: log before the trade, not after. The plan goes in pre-entry — setup, size, stop, target — so the ugly outcome can't quietly opt out of the record. This is how Trapper's Edge is built: the journal entry starts when the ticket does, and the gates read it before you size.
Two: import the broker's record. The CSV doesn't have feelings. Every fill is in there, including the ones you'd rather forget. Run the discipline read on the trades you actually took — not the ones you chose to remember.
The week you don't want to look at is the one with the answers.
The import audit is free in Trapper's Edge: bring any broker's CSV, get the honest read — win rate, rule breaks, and what they cost. No sign-up, local-first; your file never leaves your device.
