Typical Price BiasTypical Price Bias (TPB) is a normalized bias oscillator designed to quantify closing pressure relative to a bar’s typical price (HL2 = (High + Low)/2), while reducing noise through selectable moving-average smoothing.
What it measures
For each length, TPB computes:
Bias=( MA(close)−MA(HL2) ) / HL2t−1
This represents the smoothed tendency for price to close above or below typical price, scaled by the prior bar’s HL2 to produce a stable, percent-like oscillator across different markets.
Plots
Fast Bias (fast length): responsive bias component used to observe short-term pressure.
Baseline (slow length): slower bias component used as a regime/trend context line.
Zero line: neutral boundary. Above zero = bullish close bias; below zero = bearish close bias.
Visual encoding
Fast Bias coloring reflects:
Sign (above/below zero), and
Slope (increasing vs decreasing), helping you visually separate strengthening vs weakening bias.
Practical interpretation
Regime: Baseline > 0 suggests bullish conditions; Baseline < 0 suggests bearish conditions.
Confirmation: Fast Bias staying on the same side of zero as the Baseline supports continuation.
Early warning: Fast Bias turning down (while still above zero) can precede weakening momentum; similarly for upside turns below zero.
Notes
This indicator is not a complete trading system; it is best used as a filter/confirmation tool alongside structure, trend, or volatility context.
