Upper channel = highest high of last N bars; lower = lowest low; middle = midpoint. Turtle-trader breakout system.
Upper = max(High) over N bars Lower = min(Low) over N bars Middle = (Upper + Lower) / 2
Breakout systems (enter on N-day high, exit on shorter-N low). Simple, mechanical, works in trending markets.
Range-bound markets fire many false breakouts. Late entries — you're buying the high, not the pullback.
