My ST scalping model went to cash today as the ST oversold state of the past week has abated. SInce the first of my laddered entries at the close on 9/24, the model closed out the swing trade up 4.1%. In real-life, my Profunds IRA was up only 3.9% due to slippage. FWIW, I trade the entirety of my IRA, and not just a "position".
