- `periods` (`int`, Python `int`): Number of periods used for calculation.

### Returns

`TimeSeriesMovingAverage` — Time Series Moving Average indicator instance

### Examples

C#:

```csharp
var tsmaFast = Indicators.TimeSeriesMovingAverage(Bars.ClosePrices, 14);
var tsmaSlow = Indicators.TimeSeriesMovingAverage(Bars.ClosePrices, 24);
if (tsmaFast.Result.LastValue > tsmaSlow.Result.LastValue)
    Print("Fast TSMA is above slow TSMA");
```

Python:

```python
tsmaFast = api.Indicators.TimeSeriesMovingAverage(api.Bars.ClosePrices, 14)
tsmaSlow = api.Indicators.TimeSeriesMovingAverage(api.Bars.ClosePrices, 24)
if tsmaFast.Result.LastValue > tsmaSlow.Result.LastValue:
    api.Print("Fast TSMA is above slow TSMA")
```
