Prompt #007 · ChatGPT

Steelman the other side of your trade

Here is my thesis: [paste thesis]. Give me the strongest case against it in five bullets, then tell me the one piece of evidence that would prove me wrong. Do not tell me whether to buy or sell.
Prompt #008 · ChatGPT

A trade journal from your fills

Attached is a CSV of my trades with date, ticker, side, size, entry, exit and a setup tag. Group by setup. For each one show count, win rate, average hold time and the largest loss. Then list every trade where I broke one of these rules: [your rules]. Tables only, no advice.
Prompt #012 · ChatGPT

Reconcile two lists and explain the breaks

Attached are two files: [system A export] and [system B export]. Match the rows on [reference field] and amount. Give me three tables: matched, in A but not B, in B but not A. For each unmatched row, suggest the most likely reason (timing, rounding, duplicate, missing) in a few words.
