MADTREND | TaQuant x NonyaXBT

MADTREND is a trend-state indicator that blends Kalman-filtered price, a signal EMA, and ATR-based dynamic bands to identify actionable shifts in market bias. It’s designed for clarity: a single trend line that changes color on regime flips, with optional flip highlights and up/down markers—no candle recolors or visual clutter.

How it works

Kalman Filter Smoothing: Denoises price to reduce whipsaw and sharpen signal quality.

Signal Engine: EMA of the Kalman series defines the baseline trend. ATR Gates (Asymmetric):

Bullish trigger: close > EMA(Kalman) + (mult_up × ATR)
Bearish trigger: close < EMA(Kalman) – (mult_dn × ATR)

Separate up/down multipliers let you tune sensitivity to breakouts vs. breakdowns.

Visuals

• Single Trend Line: Green (up) or magenta (down) only when a regime is active; hidden in neutral.
• Flip Highlights: Soft background tint on the exact bar where the regime changes.
• Flip Markers: ▲ below bars for bullish flips, ▼ above bars for bearish flips.
