# ZigZag

#### Description <a href="#description_148" id="description_148"></a>

The ZigZag indicator searched for extreme points in different timeframes. It finds the extreme points by using threshold values that traders themselves define. These specified threshold values determine the extent to which the market direction needs to change before the ZigZag line alters its orientation and forms a further extreme point.

#### Interpretation <a href="#interpretation_65" id="interpretation_65"></a>

The previous extreme values (local highs or lows) are ideally suited for either entries or stop targets.

**Caution:** The ZigZag is not an indicator in the common sense. Position and direction of the zigzag can change retrospectively (repainting indicator).

#### Usage <a href="#usage_133" id="usage_133"></a>

```csharp
//For the upper extreme value
ZigZag(DeviationType deviationType, double deviationValue, bool useHighLow).ZigZagHigh[int barsAgo]
ZigZag(IDataSeries inSeries, DeviationType deviationType, double deviationValue, bool useHighLow).ZigZagHigh[int barsAgo]

//For the lower extreme value
ZigZag(DeviationType deviationType, double deviationValue, bool useHighLow).ZigZagLow[int barsAgo]
ZigZag(IDataSeries inSeries, DeviationType deviationType, double deviationValue, bool useHighLow).ZigZagLow[int barsAgo]
```

#### Return value <a href="#return-value_131" id="return-value_131"></a>

**double**

When using this method with an index (e.g. **ZigZag**(...)\[**int** barsAgo] ), the value of the indicator will be issued for the referenced bar.

A return value of 0 indicates that no high or low point has been found yet.
