Convex Hull Channel [forexobroker]
🔶 OVERVIEW
Convex Hull Channel forms a tight envelope from the rolling maximum of body-tops (max of open and close) and minimum of body-bottoms (min of open and close), filtering wick spikes that classic Donchian channels reward. An expansion regime, defined as channel width above its 50-bar average, gates breakout signals to high-volatility periods only.
🔶 ALGORITHM
1. body_high = max(open, close); body_low = min(open, close).
2. upper = ta.highest(body_high, N); lower = ta.lowest(body_low, N).
3. width = upper - lower; expansion regime when width >= width_avg * (1 + k).
4. Buy break: close crosses prior bar's upper envelope inside expansion regime.
5. Sell break: close crosses prior bar's lower envelope inside expansion regime.
🔶 SIGNAL LOGIC
- Buy: expansion AND close crosses upper[1] AND not already long AND cooldown elapsed AND barstate.isconfirmed.
- Sell: expansion AND close crosses lower[1] AND mirror conditions.
- Position-lock state machine.
🔶 INPUTS
- Envelope Window (default 20)
- Min Width Excess (default 0.20)
- Cooldown Bars (default 4)
- Visual: dashboard, glow, envelope bands, buy / sell colors
🔶 ALERTS
CHC Buy, CHC Sell, CHC Any Signal, CHC Expansion On, CHC Expansion Off, CHC Upper Cross, CHC Lower Cross, CHC Outside, CHC Webhook JSON.
🔶 LIMITATIONS
- Body-only envelope gives fewer false breaks than wick-inclusive Donchian, but can miss legitimate moves that close back inside the body range.
- Expansion regime is rolling-average relative; a long quiet period followed by even modest expansion will fire whereas absolute-width logic might not.
- Cross-of-prior-bar (upper[1]) introduces a 1-bar delay vs immediate-bar break; intentional, reduces noise.
- Defaults tuned for 15m-1H on majors and indices; very fast scalping timeframes may want a smaller window.
