Exit position 1 second after buy/sell

[diorfo]

Hello,

I would like to know if it's possible exit a position 1 second after enter it.

I tried something like below but seems to work only in minute frame:


private double enterPrice
private int startTime

protected override void OnMarketData(MarketDataEventArgs marketDataUpdate)
{
EnterLongLimit(1, enterPrice, "Buy");
startTime = ToTime(Time[0]);

if (ToTime(Time[0]) >= startTime + 000001 && Position.MarketPosition == MarketPosition.Long)
{
ExitLong(@"exit_TPM_Buy", @"Buy");
}
}

Could anyone help me with correct code for second frame?

Hello diorfo,

You have the right idea but you need a condition for the long limit entry and the setting of startTime . You need to stop setting startTime once the limit entry fills so it has a specific fixed time. Once you do that the condition you have would be the way to do that type of action after 1 second however there is a easier way to add 1 second. You also need to consider the time that you used.

To check 1 second from a given time you can do something like the following. I added a Flat condition so that the setting of startTime stops once the entry has filled.

private DateTime startTime;
​
protected override void OnMarketData(MarketDataEventArgs marketDataUpdate)
{
    if(Position.MarketPosition == MarketPosition.Flat) // or some condition for your entry that remains true while the limit order is unfilled so it does not expire
    {
        EnterLongLimit(1, enterPrice, "Buy");
        startTime = Time[0].AddSeconds(1);
    }
    else if(Position.MarketPosition == MarketPosition.Long)
    {
         if (Time[0] >= startTime)
         {
              ExitLong(@"exit_TPM_Buy", @"Buy");
          }  
    }​
}

There are a few considerations to make here.

Time[0] is your bar series time. If you used a 1 minute bar then adding 1 second would be the last bar close time plus 1 second. The times you are checking are in 1 minute intervals. If you want the latest time you can use the incoming market data time in OnMarketData:

startTime = marketDataUpdate.Time.AddSeconds(1);

 if (marketDataUpdate.Time >= startTime)

When using OnMarketData that is realtime only, to be able to backtest this script you would need to use TickReplay.

If you wanted to use times from a secondary series you can use the Times series.

 startTime = Times[1][0].AddSeconds(1);

if (Times[1][0] >= startTime)
