Pulse Echo Indicator is a non-repainting volatility-adaptive trend envelope for MetaTrader 5. Instead of relying on a single fixed-length moving average, it continuously rebalances a fast (default 7) and slow (default 34) EMA based on the ratio of short-term to long-term realized volatility, producing a single trend spine that hugs price tightly in calm markets and flattens against noise in volatile ones. An EWMA-variance band sized in proportion to the spine and current sigma defines bullish and bearish breakouts, and a three-state regime machine (bull / bear / neutral) drives the visible trend color, painted candles, and Buy/Sell labels at every confirmed transition.

How It Works
Adaptive Trend Spine
The indicator computes log returns of the source price (default close) and feeds them into two rolling standard-deviation windows: a 20-bar short-term volatility (volS) and an 80-bar long-term volatility (volL). The ratio vr = volS / volL is mapped to a blend weight via wRaw = clamp(1 - (vr - 0.7) / 0.9, 0, 1) . The weight is smoothed by a 30-bar EMA, then used to combine the fast and slow EMAs into a raw spine: spineRaw = w * emaFast + (1-w) * emaSlow . A second 30-bar EMA smooths the result into the visible trend line. When volatility is low, the weight pulls the spine toward the fast EMA; when volatility expands, it pulls toward the slow EMA. The transition is smooth because the weight itself is EMA-smoothed.
EWMA-Variance Envelope
An exponentially-weighted moving variance of log returns (decay alpha = 0.09) produces realized sigma at every bar. The envelope half-width is spine * sigma * 1.9 , with upper and lower bands above and below the spine. When the close of a confirmed bar exceeds the upper band, the regime transitions to bull (+1). When it falls below the lower band, bear (-1). When the regime is bull and price closes below the spine, it returns to neutral (0); same in reverse for bear. This three-state logic filters whipsaws while still capturing every real reversal.
Visual Layers
Each visible bar receives multiple layers of feedback: the trend spine line color changes with the active regime; candle bodies are recolored in the bull or bear color (last 500 bars by default); a colored fill connects close to the spine's anchor when they diverge; a thin rim band hugs close 6% of ATR away. At every regime transition (bull-start or bear-start), a yellow "Buy" or "Sell" text on a colored pill is placed 2.5 ATRs above or below the bar's high or low — far enough to never overlap candle wicks.
Key Features
- Volatility-adaptive blend of fast (7) and slow (34) EMA driven by realized volatility ratio

- Trend candles repainted in the active regime color (default lime / red)
- Energy fills between close and the trend spine, colored by direction
- Thin rim band (6% of ATR) hugging close as a low-noise regime indicator
- Yellow "Buy"/"Sell" pill labels at every regime transition, positioned 2.5 ATRs from price
- Non-repainting: signals fire only on confirmed bar close and never disappear
- 4 alert conditions: Bull Trend Start, Bear Trend Start, Trend Exit, Spine Cross
- 4 delivery channels: Popup, Sound, Push notification, Email
