A checklist, not odds on a return: 3 of 5 usable price conditions have to line up. RSI, the 50-day average and the Bollinger band move with the price you set; the 20-day average traded price, the entry level and the busiest put strike stay fixed. MACD, RVol, Short int. and ATR are context only — they never count toward the total.
