SPY trades at 682.11 in premarket, a decline of 0.44% from Tuesday's close of 685.13. The 8-day simple moving average at 683.50 — a cornerstone of Saty Mahajan's 8-21-34 Pivot Ribbon system — has repelled two recovery attempts. SPY now trades below the Saty ATR put trigger at 681.10, a signal that favors directional put buying per the Fibonacci ATR methodology.
The Volume Stack indicator shows 50.6% sell pressure — a marginal but meaningful lean. Power hours per Saty's system: 9:30–11:30 AM and 3:00–4:00 PM ET. We are in early March, which per Saty's monthly cadence calls for aggressive deployment (0–90% of capital).
