# 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

See [*KeyReversalUp*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#keyreversalup), [*KeyReversalDown*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#keyreversaldown), [*KeyReversalUpAtSMA*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#keyreversalupatsma), [*KeyReversalDownAtSMA*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#keyreversaldownatsma), [*KeyReversalUpAtEMA*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#keyreversalupatema).

#### 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

#### Usage <a href="#usage_48" id="usage_48"></a>

```csharp
KeyReversalDownAtEMA(int period, int EMAperiod)
KeyReversalDownAtEMA(IDataSeries inSeries, int period, int EMAperiod)
KeyReversalDownAtEMA(int period, int EMAperiod)[int barsAgo]
KeyReversalDownAtEMA(IDataSeries inSeries, int period, int EMAperiod)[int barsAgo]
```

#### Example <a href="#example_46" id="example_46"></a>

```csharp
// Search for a short entry
if (KeyReversalDownAtEMA(10)[0] == 1)
Print("A short reversal formation has occurred.");
