Timer to remove alert after x seconds

[mlarocco]

Hi all,
I have an indicator that alerts when a calculated volume level is exceeded and displays text on the chart. What I would like is, to have the text(alert) removed from the chart after say 15 seconds from when it triggered. I have looked at the BarTimer but can't understand how to get that to work for this.

As always, your help is appreciated!

You could trigger a timerevent that would run irregardless if there is data coming through on the chart.

Easier option would be to store the time and do a check to see if 15 seconds has lapsed.

Would the second (easier) option work in market replay as well? Does it get time from NinjaTrader or the PC?

Thanks!

That uses market replay.

Great! Thank you

Having trouble getting the time variable when it triggers. Here is the code I'm using...

timer = ToTime(Time[0]);
Print ("Time is " + timer);

The output from the Print command returns the time but with 00 seconds, can't seem to store the seconds. Here's the output window text....

Time is 90100

The actual time it triggered at was 9:00:19 AM

It looks like it will be an issue.

Post #8 from NT_PatrickH explains how to get around it.

What timeframe is the chart?

I am using a 1 minute chart. Apparently, this is normal behavior. I was able to add the time period for a 1 second chart and then count the bars after the alert was triggered.....


Add(PeriodType.Second, 1);

if (timer == 0)
timer = CurrentBars[1];

if (My Condition)
{
timer = CurrentBars[1];
}

if ((timer + 15) == CurrentBars[1])
{
RemoveDrawObject("Trigger");
}


Works great
