How to limit strategy to one trade per day?

[Billy Valentine]

I have a strategy that works well--sort of--except that I only want it to take only one trade per day. Any ideas?

Billy, you'll have to use some sort of a true/false (boolean) flag to check whether or not a trade has been placed already in the day combined with a date/time checker to reset the flag every new day.

Something like this:

// in variables
bool alreadyTradedToday = false;

OnBarUpdate()
{
   if (CurrentBar < 2) return;
   if (Time[0].DayOfWeek != Time[1].DayOfWeek) // new day, reset bool flag
   {   alreadyTradedToday = false; }

   if ([Long Entry Conditions are true] && alreadyTradedToday == false)
   {
      alreadyTradedToday = true;
      EnterLong();
   }
   
    // same, but opposite for shorts
}

Thanks, Austin. I'll give it a try.

This is really useful thanks!

How would you change it if you only wanted 1 trade per month?

Thanks!

Hello freddy250,

Thank you for your inquiry.

All you would need to do is change Time[0].DayOfWeek and Time[1].DayOfWeek to Time[0].Month and Time[1].Month.

I would suggest looking at this link to learn more about the DateTime structure, which is what a Time[index] returns: https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx

Please, let us know if we may be of further assistance.
