# AcceleratorOscillator (interface)

Identifies possible trend reversals

Environments: Desktop supported · CLI supported · Cloud supported.

## Definition

```csharp
public interface AcceleratorOscillator
```

## Examples

C#:

```csharp
var acceleratorOscillator = Indicators.AcceleratorOscillator();
Print("Accelerator Oscillator: {0}", acceleratorOscillator.Result.LastValue);
```

Python:

```python
acceleratorOscillator = api.Indicators.AcceleratorOscillator()
api.Print(f"Accelerator Oscillator: {acceleratorOscillator.Result.LastValue}")
```

C#:

```csharp
using cAlgo.API;
using cAlgo.API.Indicators;

namespace cAlgo.Robots
{
    // This sample cBot shows how to use an Accelerator Oscillator indicator
    public partial class AcceleratorOscillatorSample : Robot
    {
        private double _volumeInUnits;

        private AcceleratorOscillator _acceleratorOscillator;

        public Position[] BotPositions
        {
            get
            {
                return Positions.FindAll(Label);
            }
        }

        protected override void OnStart()
        {
            _volumeInUnits = Symbol.QuantityToVolumeInUnits(VolumeInLots);

            _acceleratorOscillator = Indicators.AcceleratorOscillator();
        }

        protected override void OnBar()
        {
            foreach (var position in BotPositions)
            {
                if ((position.TradeType == TradeType.Buy && _acceleratorOscillator.Result.Last(1) < _acceleratorOscillator.Result.Last(2))
                    || (position.TradeType == TradeType.Sell && _acceleratorOscillator.Result.Last(1) > _acceleratorOscillator.Result.Last(2)))
                {
                    ClosePosition(position);
                }
            }

            if (_acceleratorOscillator.Result.Last(1) > 0 && _acceleratorOscillator.Result.Last(2) <= 0)
            {
                ExecuteMarketOrder(TradeType.Buy, SymbolName, _volumeInUnits, Label, StopLossInPips, TakeProfitInPips);
            }
            else if (_acceleratorOscillator.Result.Last(1) < 0 && _acceleratorOscillator.Result.Last(2) >= 0)
            {
                ExecuteMarketOrder(TradeType.Sell, SymbolName, _volumeInUnits, Label, StopLossInPips, TakeProfitInPips);
            }
        }
    }
}
```

```python
import clr

clr.AddReference("cAlgo.API")

# Import cAlgo API types
