# WeightedMovingAverage (interface)

The Weighted Moving Average is a moving average that gives more weith to the latest values.

Environments: Desktop supported · CLI supported · Cloud supported.

## Definition

```csharp
public interface WeightedMovingAverage
```

## Examples

C#:

```csharp
private WeightedMovingAverage _weightedMovingAverage;

protected override void OnStart()
{
    _weightedMovingAverage = Indicators.WeightedMovingAverage(Bars.ClosePrices, 14);
}

protected override void OnTick()
{
    if (Symbol.Bid > _weightedMovingAverage.Result.LastValue)
        Print("Bid {0} is above the Weighted Moving Average {1}", Symbol.Bid, _weightedMovingAverage.Result.LastValue);
}
```

Python:

```python
def on_start(self):
    self.weightedMovingAverage = api.Indicators.WeightedMovingAverage(api.Bars.ClosePrices, 14)

def on_tick(self):
    if api.Symbol.Bid > self.weightedMovingAverage.Result.LastValue:
        api.Print(f"Bid {api.Symbol.Bid} is above the Weighted Moving Average {self.weightedMovingAverage.Result.LastValue}")
```

C#:

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

namespace cAlgo.Robots
{
    // This sample cBot shows how to use the Weighted Moving Average indicator
    public partial class WeightedMovingAverageSample : Robot
    {
        private double _volumeInUnits;

        private WeightedMovingAverage _fastWeightedMovingAverage;

        private WeightedMovingAverage _slowWeightedMovingAverage;

        public Position[] BotPositions
        {

            _slowWeightedMovingAverage = Indicators.WeightedMovingAverage(SlowMaSource, SlowMaPeriod);
        }

        protected override void OnBar()
        {
            if (_fastWeightedMovingAverage.Result.HasCrossedAbove(_slowWeightedMovingAverage.Result, 0))
            {

            }
            else if (_fastWeightedMovingAverage.Result.HasCrossedBelow(_slowWeightedMovingAverage.Result, 0))
            {
                ClosePositions(TradeType.Buy);
