# Squeeze Pro (Indicator)
|
|
|
|
## 1. Summary (Introduction)
|
|
|
|
The `Squeeze_Pro` is a professional-grade implementation of the popular "TTM Squeeze" concept, originally developed by John Carter. It is a volatility-based indicator designed to identify moments where the market consolidates ("Squeezes") before a significant directional move ("Fires").
|
|
|
|
The indicator visualizes the relationship between Volatility compression (Bollinger Bands vs. Keltner Channels) and Momentum, helping traders stay out of choppy markets and position themselves for explosive breakouts.
|
|
|
|
## 2. Methodology and Logic
|
|
|
|
The Squeeze principle relies on the interaction between two volatility envelopes:
|
|
|
|
1. **Bollinger Bands (BB):** Measure standard deviation volatility. They expand during high volatility and contract during low volatility.
|
|
2. **Keltner Channels (KC):** Based on Average True Range (ATR). They represent the "normal" volatility range.
|
|
|
|
### The "Squeeze" State (Logic)
|
|
|
|
* **SQUEEZE ON (Red Dot):** When the Bollinger Bands contract completely *inside* the Keltner Channels. This indicates extremely low volatility—the market is building energy.
|
|
* **SQUEEZE OFF (Green Dot):** When the Bollinger Bands expand *outside* the Keltner Channels. The energy is released, and a trend move begins.
|
|
|
|
### Momentum Histogram
|
|
|
|
To determine the *direction* of the potential breakout, the indicator calculates a momentum oscillator (Price Delta from the mean of the Donchian Channel and SMA).
|
|
|
|
* **Rising Histogram:** Increasing bullish momentum.
|
|
* **Falling Histogram:** Increasing bearish momentum.
|
|
|
|
## 3. MQL5 Implementation Details
|
|
|
|
The indicator is built on the robust "Professional Indicator Suite" framework, ensuring high performance and modularity.
|
|
|
|
* **Calculator Engine (`Squeeze_Calculator.mqh`):**
|
|
The core logic is encapsulated in a dedicated class that orchestrates the `CBollingerBandsCalculator` and `CKeltnerChannelCalculator`. This Composition Pattern allows for clean code and O(1) incremental calculation efficiency.
|
|
* **Visual Efficiency:**
|
|
It utilizes a `DRAW_COLOR_ARROW` plot for the Squeeze dots, allowing instant visual feedback on the Zero line without cluttering the chart.
|
|
* **Price Source:**
|
|
This indicator strictly uses **Standard Prices** (Close, High, Low) for calculations. Heikin Ashi is intentionally avoided to preserve the statistical integrity of the volatility measurement (High/Low range).
|
|
|
|
## 4. Parameters
|
|
|
|
* **Squeeze Settings:**
|
|
* `InpPeriod`: The lookback period for both BB and KC (Default: `20`).
|
|
* `InpBBMult`: Standard Deviation multiplier for BB (Default: `2.0`). High values make the Squeeze harder to trigger.
|
|
* `InpKCMult`: ATR multiplier for KC (Default: `1.5`).
|
|
* **Momentum Settings:**
|
|
* `InpMomPeriod`: The smoothing window for the Momentum histogram (Default: `12`).
|
|
|
|
## 5. Usage and Interpretation
|
|
|
|
1. **The Setup (Red Dots):**
|
|
Look for a series of **Red Dots** on the zero line. This is the accumulation phase. **Do not trade yet.** Wait for the expansion.
|
|
2. **The Trigger (Green Dot):**
|
|
When the first **Green Dot** appears after a series of Red Dots, the Squeeze has "fired".
|
|
3. **Direction:**
|
|
Look at the Momentum Histogram at the moment of the trigger:
|
|
* **Positive (Blue) Histogram:** Buy Signal (Long).
|
|
* **Negative (Red) Histogram:** Sell Signal (Short).
|
|
4. **Exit:**
|
|
Consider exiting the trade when the Momentum Histogram starts to decline (changes color shade) or returns to zero.
