// GP - Combined EMA Early Retest + SRSI Channel Filter
This script combines two complementary approaches into a filtered momentum and pullback retest system.
The core concept is to generate **high-probability entry signals** by requiring confirmation from both price action structure (via EMA pullback & early retest) and multi-timeframe momentum extremes (via SRSI Channel).
### Indicator A – EMA Early Retest Logic
This part identifies potential early retest entries after a strong move:
- Uses a triple EMA system (Fast 20 / Mid 50 / Slow 100 by default).
- Detects when the fast EMA crosses the mid or slow EMA, then tracks the subsequent pullback.
- Measures pullback depth as a percentage of the prior impulse move.
- Triggers a signal when price (via fast EMA) returns to an **early retest zone** (default 90% of the pullback), but only in the direction of the higher trend (Mid vs Slow EMA).
This logic aims to catch early resumption of the trend instead of waiting for a full retest of the swing low/high.
### Indicator B – Multi-Timeframe SRSI Channel
Provides higher-timeframe momentum context:
- Calculates Stochastic RSI (K+D) on open, high, low, and close.
- Aggregates values from **four higher timeframes** (default: 3H, 6H, 12H, 24H).
- Detects momentum extremes and confirms reversals after a set number of bars (default 10 bars confirmation).
- Acts as a powerful **momentum filter** to avoid signals against the broader momentum.
### Combined Filter System
The final signals are **filtered** using a 1-week lookback:
- A buy signal from the EMA Early Retest is only valid if the SRSI Channel has recently confirmed a momentum low (oversold reversal).
- A sell signal is only valid if the SRSI Channel has recently confirmed a momentum high (overbought reversal).
This filter significantly reduces false signals by ensuring that short-term price action aligns with broader momentum shifts.
### How to Use
**Bullish (Long) Signal:**
- Lime triangle appears below the bar.
- Indicates the fast EMA has pulled back and is retesting early in an uptrend, confirmed by recent multi-timeframe SRSI momentum low.
**Bearish (Short) Signal:**
- Red triangle appears above the bar.
- Indicates the fast EMA has pulled back and is retesting early in a downtrend, confirmed by recent multi-timeframe SRSI momentum high.
**Visual Elements:**
- Orange = Fast EMA (most responsive)
- Blue = Mid EMA
- Gray = Slow EMA (trend filter)
- Light triangles = Original EMA signals (filtered out)
- Bright triangles = **Filtered high-probability signals**
### Recommended Usage
- Best suited for **intraday and swing trading** on 5m, 15m, 30m, and 1H timeframes.
- Works well on major forex pairs, indices, and cryptocurrencies.
- Use in the direction of the higher timeframe trend for better performance.
- Combine with support/resistance, order blocks, or volume analysis for maximum edge.
### Settings Tips
- Adjust "Pullback depth (%)" and "Early retest ratio" to match market volatility.
- Modify higher timeframe settings in "Indicator B" group to suit your trading style.
- Increase "Confirm bars" for stricter (fewer but higher quality) signals.
This is **not** a simple mashup of indicators. The real value comes from the intelligent combination of **price structure (EMA retest)** with **multi-timeframe momentum confirmation**, plus the 1-week lookback filter.
