Resetting a variable at a designated time

August 26th, 2013, 08:00 PM

I have an On Balance Volume indicator that keeps a running tally of volume. I want to reset the total to 0 at a designated time, say 1:00am. Can someone give me some advice on how to code this?

Here is the current code:

Code

protected override void OnBarUpdate()
        {
            // Set the initial plot value to 0 on the first bar
	if (CurrentBar == 0)
	    Value.Set(0);
			
	else
	    Value.Set(Value[1] + (UpDownTradeVolumeNV().UpVolume[0] - 
                    UpDownTradeVolumeNV().DownVolume[0]));
         }

Thanks,
Ron

You could try something like this:

Code

protected override void OnBarUpdate()
{
    // Set the initial plot value for the first bar of each session
    if (Bars.FirstBarOfSession)
       Value.Set( (UpDownTradeVolumeNV().UpVolume[0] - 
             UpDownTradeVolumeNV().DownVolume[0]));
			
   else
       Value.Set(Value[1] + (UpDownTradeVolumeNV().UpVolume[0] - 
             UpDownTradeVolumeNV().DownVolume[0]));
}

Not sure that it will work, as you have only shared a fraction of your code.

if ((Time[0].Hour == 1) && (Time[0].Minute== 0) && (Time[0].Second == 0))
Print("Do something");

Make sure your bar series actually breaks at 1:00am or it will skip over.

use "<" or ">" against the time mark then.

use "<" or ">" against the time mark then.

Or to be more accurate:

-> for charts built from ticks (tick, volume, range, renko) use ">=" or "<="
-> for minute or second charts use ">" or "<"

The reason here is that a minute bar with a time stamp 1:00:00 AM covers the minute prior to 1:00:00 AM, while a tick bar - or volume, range or renko bar - with a time stamp 1:00:00 AM covers a period after 1:00:00 AM.
