# KeyReversalUpAtEMA

#### Description <a href="#description_46" id="description_46"></a>

KeyReversalUpAtEMA searches within a predefined number of periods to find a reversal formation 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 lowest low within the last n bars 3 The current low 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), [*KeyReversalDownAtEMA*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#keyreversaldownatema).

#### Parameters <a href="#parameters_41" id="parameters_41"></a>

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

#### Return value <a href="#return-value_46" id="return-value_46"></a>

**double**

0 – No reversal information found 1 – Reversal information found

#### Usage <a href="#usage_47" id="usage_47"></a>

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

#### Example <a href="#example_45" id="example_45"></a>

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