Luis channel
Luis Barlier Channel (LB Channel) – Technical Overview
1. Core Concept & Calculations
The LB Channel is a price envelope indicator that generates three lines based on a lookback period (default: 20 bars).
Key Innovation: Ignores wicks entirely, focusing only on candle bodies:
Body High (BH):
max(open, close)
max(open, close)
Body Low (BL):
min(open, close)
min(open, close)
Channel Lines:
Upper Bound:
Highest(BH,length)
Highest(BH,length)
Lower Bound:
Lowest(BL,length)
Lowest(BL,length)
Basis (Middle):
(Upper+Lower)/2
2. Visual & Functional Features
Dynamic S/R Zone: Blue boundaries act as support/resistance, updating only when new body highs/lows break prior extremes.
Value Area Fill: Light blue shading (90% transparency) highlights if price is "inside" or "outside" the recent range.
Offset Control: Shift entire channel forward/backward for cycle analysis.
3. The Problem It Solves: Wick Noise
Traditional channels (Donchian, Bollinger) react to volatility spikes:
Long wicks from news/liquidity hunts artificially widen ranges
Generate false breakouts
Distort "fair value"
LB Channel Solution: Filters noise by using only committed price action (body highs/lows), ignoring temporary spikes that lack follow-through.
