# KeyReversalUp

#### Description <a href="#description_42" id="description_42"></a>

The KeyReversalUp indicator searches within a predefined number of periods to find turning points with the following characteristics: 1 The current close is higher than the previous close 2 The current low is smaller than or equal to the last low of the last n bars

inSeries Input data series for the indicator period Number of bars included in the calculations

#### Return value <a href="#return-value_42" id="return-value_42"></a>

**double**

0 – No reversal information available 1 – Reversal information available

#### Usage <a href="#usage_43" id="usage_43"></a>
