# KeyReversalDownAtEMA

#### Description <a href="#description_47" id="description_47"></a>

KeyReversalDownAtEMA searches within a predefined number of periods to find a reversal formation with the following characteristics:

1 The current close is lower than the previous close 2 The current high is larger than or equal to the highest high of the last n bars 3 The current high has touched or breached an EMA

#### Parameters <a href="#parameters_42" id="parameters_42"></a>

inSeries Input data series for the indicator period Number of bars included in the calculations EMAperiod Number of periods used to calculate the EMA

#### Return value <a href="#return-value_47" id="return-value_47"></a>

**double**

0 – No reversal formation found

1 – Reversal formation found
