How to compute classic floor-trader pivot points

1. Enter prior high

   "Prior high" is the highest price during the previous completed session (yesterday's high for daily pivots, last week's high for weekly). Must be ≥ low — otherwise the tool errors out.

2. Enter prior low

   "Prior low" is the lowest price during the same session. Mid-session updates won't change the pivots; the formula uses prior session's H/L/C, not intraday.

3. Enter prior close

   "Prior close" is the closing print from that same session. For 24-hour markets (FX, crypto), pick a consistent session boundary — usually New York close.

4. Press Run

   Result returns pivot = (H+L+C)/3, r1 = 2P − L, s1 = 2P − H, r2 = P + (H−L), s2 = P − (H−L), each rounded to 6 decimals. Use levels for support/resistance, not as signals on their own.
