Reddit startup idea
Stop-Loss Forensics Studio
A trading post-mortem and journaling web app that automatically classifies stop-outs (noise vs. structure break vs. sweep) and quantifies how alternative stop placements would have changed outcomes. Users connect their broker/export trades, and the app reconstructs the stop-out context with volatility bands, nearby liquidity levels, and time-of-day patterns to produce actionable rules like "minimum stop distance = X ATR in first 30 minutes".

Target customer
Active retail day traders and small prop-style traders (manual execution) who trade equities/options intraday and suffer frequent stop-outs and inconsistent results.
Problem-solution fit
The post shows a recurring, emotionally and financially costly issue: stops get hit repeatedly, then trades work without them. The product addresses this by turning each stop-out into structured evidence: quantify whether stops are systematically too tight, placed at obvious levels, or entered too early, then recommend concrete, testable stop/entry rules tailored to the user’s instrument and timeframe.
