# TTM_SCALPER: TTM Scalper Alert
> **Pending Implementation** - Placeholder for John Carter's TTM Scalper Alert indicator
## Historical Context
John Carter designed TTM Scalper Alert for quick identification of potential reversal points using a simple three-bar pattern recognition. The indicator marks pivot highs and lows that can serve as entry triggers for scalping strategies, particularly when combined with other TTM suite indicators.
## Algorithm
### Pivot High Detection
```
pivotHigh = high[1] > high[2] AND high[1] > high[0]
// Three consecutive bars where middle bar has highest high
```
### Pivot Low Detection
```
pivotLow = low[1] < low[2] AND low[1] < low[0]
// Three consecutive bars where middle bar has lowest low
```
### Alternative: Close-Based Version
```
pivotHigh = close[1] > close[2] AND close[1] > close[0]
pivotLow = close[1] < close[2] AND close[1] < close[0]
```
## Default Parameters
| Parameter | Value | Description |
|:----------|:------|:------------|
| UseCloses | false | Use close prices instead of high/low |
| ShowPaintBars | true | Color bars at pivot points |
## Outputs
| Output | Type | Description |
|:-------|:-----|:------------|
| PivotHigh | bool | True on confirmed pivot high (painted on bar-1) |
| PivotLow | bool | True on confirmed pivot low (painted on bar-1) |
| PivotHighPrice | double | Price level of pivot high |
| PivotLowPrice | double | Price level of pivot low |
## Visual Markers
- **▼ (Down Triangle):** Pivot high - potential short entry
- **▲ (Up Triangle):** Pivot low - potential long entry
- Markers appear one bar after confirmation (on the middle bar of the 3-bar pattern)
## Trading Strategy
1. **Long Entry:** Pivot low signal + TTM Squeeze firing bullish + TTM Trend bullish
2. **Short Entry:** Pivot high signal + TTM Squeeze firing bearish + TTM Trend bearish
3. **Stop Placement:** Beyond the pivot point high/low
