Time Limit Help

[26psicivic]

Hello I'm hoping someone can tell me how to put a time limit on something. For example, if I have an int variable that counts something. I want to reset it back to 0 every 60 seconds.
Thanks in advance.

Hello 26psicivic,

You can use an integer as a counter that is incremented on every event (like OnBarUpdate() updating).

Below is a link to a forum post that discusses and has sample code.

If you add a 1 minute (or 60 second) series with AddDataSeries you can reset this back to 0 in the BarsInProgress index of that series every 60 seconds.

I was wanting to know how to use time to reset the integer. I want to only allow a certain amount of time for something to happen.
Let's try another example. If I have a 2 step entry process where 2 conditions have to be met. When the first condition is met I want to allow 60 seconds for the second condition to be met. If the second condition is met then that will be my entry. If the second condition is not met then it will start over with the first condition.

Hello 26psicivic,

By adding a 60 second series, this would cause OnBarUpdate() to update every 60 seconds (in both historical and realtime).

private bool checkingSecondCondition;

AddDataSeries(BarsPeriodType.Second, 60);

if (BarsInProgress == 0)
{
if (/*first conditions*/)
{
checkingSecondCondition = true;
}

if (checkingSecondCondition == true && /* second conditions /*)
{
// second condition was true within 60 seconds
}
}
else if (BarsInProgress == 1)
{
checkingSecondCondition = false; // reset back to false after 60 seconds
}

You could also add a 1 second series and check that the Time[0].Minute is 0.

If you not interested in this working in historical and having this work in real-time only, you could use a timer.

Oh ok, I see what you're saying. Will this still work if I already have other data series?

Hello 26psicivic,

Yes, multiple data series can be added with AddDataSeries().
