Trading-Journal Invalidation Notes in Crypto: When the Common Rule Produces a Misleading Result
'Write an invalidation before every trade' helps only if the note is testable. Vague notes can be reinterpreted after the fact.
Short answer
An invalidation note like 'exit if it looks weak' gives no clear exit, so the trade can always be rationalised. Testable notes specify a condition, timeframe and action: '1H close below 59,400 → exit at market next bar'. In reviews, measure how often exits matched notes and the cost of deviations. A journal full of vague notes shows 100% compliance and no information.

| Testable | '1H close < 59,400 → exit next bar' |
| Review | Exit matched note? |
| Deviation cost | Actual − planned exit |
| Compliance | Meaningful only if testable |

Arithmetic uses standard sizing formulas. Fee rates (0.05% taker, 0.02% maker), slippage and funding values are illustrative; check your venue's schedule. Liquidation figures are simplified approximations; exchanges calculate them with their own maintenance-margin rules (see Bybit's documentation).
