## Syntax

`\<sessioniterator\>.GetTradingDayBeginLocal(DateTime tradingDayExchange)`

## Parameters

| Parameter          | Description                                           |

| tradingDayExchange | The DateTime value used to calculate the trading day. |

## Examples

```csharp
private SessionIterator sessionIterator;

protected override void OnStateChange()
{
    if (State == State.DataLoaded)
    {
        //stores the sessions once bars are ready, but before OnBarUpdate is called
        sessionIterator = new SessionIterator(Bars);
    }
}

protected override void OnBarUpdate()
{
    // Only process strategy logic starting three hours after trading begins at the exchange
    if (Core.Globals.Now >= sessionIterator.GetTradingDayBeginLocal(sessionIterator.ActualTradingDayExchange).AddHours(3))
    {
        // Strategy logic here
    }
}
