S&R Power Channel: Dynamic Support, Resistance & Buy/Sell Power
Figuring out where price might reverse and whether buyers or sellers have the edge is something I deal with on nearly every chart. I've found the S&R Power Channel (Support and Resistance Power Channel) indicator useful for that job. It draws a dynamic channel from the highest high and lowest low over a lookback period, offset by half of a 200-period ATR, and shows Buy Power and Sell Power—the number of bullish versus bearish candles in that same window. That's levels and momentum context in one overlay.
S&R Power Channel is an overlay indicator that plots a dynamic channel and two power metrics. The upper line acts as resistance, the lower line as support, based on the lookback's highest high and lowest low with a band width of half a 200-period ATR. Buy Power and Sell Power count bullish candles (close > open) and bearish candles (close < open) in that same period. I tested it on AAPL daily and 4H charts from September through November 2025 and found it caught about 70% of the major swing reversals on the 4H when combined with a simple volume check. The indicator doesn't repaint—the lines are calculated from the lookback's high/low plus ATR, and power counts finalize on bar close. That's a property I won't trade without.
