# TTM_SQUEEZE: TTM Squeeze
|
||
|
|
|
||
|
|
> **Pending Implementation** - Placeholder for John Carter's TTM Squeeze indicator
|
||
|
|
|
||
|
|
## Historical Context
|
||
|
|
|
||
|
|
John Carter developed TTM Squeeze as his signature volatility breakout indicator, popularized through his book *Mastering the Trade* and thinkorswim platform. The indicator combines Bollinger Bands and Keltner Channels to identify low-volatility "squeeze" conditions that typically precede explosive price moves.
|
||
|
|
|
||
|
|
## Algorithm
|
||
|
|
|
||
|
|
### Squeeze Detection
|
||
|
|
- **Squeeze On (●):** Bollinger Bands inside Keltner Channel
|
||
|
|
- **Squeeze Off (○):** Bollinger Bands outside Keltner Channel
|
||
|
|
|
||
|
|
### Momentum Histogram
|
||
|
|
Linear regression of price deviation from 20-period midline:
|
||
|
|
```
|
||
|
|
midline = (Highest(20) + Lowest(20)) / 2
|
||
|
|
momentum = LinReg(close - midline, 20)
|
||
|
|
```
|
||
|
|
|
||
|
|
### Color Coding
|
||
|
|
- **Cyan:** Momentum rising above zero
|
||
|
|
- **Blue:** Momentum falling but above zero
|
||
|
|
- **Red:** Momentum falling below zero
|
||
|
|
- **Yellow:** Momentum rising but below zero
|
||
|
|
|
||
|
|

||
|
|
| Output | Type | Description |
|
||
|
|
|:-------|:-----|:------------|
|
||
|
|
| Momentum | double | Linear regression momentum value |
|
||
|
|
| SqueezeOn | bool | True when BB inside KC |
|
||
|
|
| MomentumRising | bool | True when momentum increasing |
|
||
|
|

||
|
|
1. **Squeeze Fired:** First bar where SqueezeOn transitions to false
|
||
|
|
2. **Long Entry:** Squeeze fires + momentum positive + momentum rising
|
||
|
|
3. **Short Entry:** Squeeze fires + momentum negative + momentum falling
