Ledge's setup — hourly pivots clustered into cross-timeframe-confirmed price zones, traded on a clean break — run on SPY/QQQ/IWM against same-day (0DTE) contracts instead of 14-21 DTE. Same zone clustering, computed once a day off hourly bars, but no multi-week option to carry: a tighter stop-loss and a hard end-of-day flatten replace the wider risk budget the monthly version can afford.
