Quote Values not updating in pre-market

September 28th, 2023, 09:35 AM

I have a simple daily RVOL indicator in radarscreen that uses the DailyVolume quote field.
I am using DailyVolume so that I can reference pre-market volume in my calculation.
In pre-market, DailyVolume does not update per tick when I reference Volume or Volume[n] in the same code, but updates
as expected in the regular session.

This code would produce non-updating DailyVolume values in pre-market:

plot1(DailyVolume);
plot2(volume);

If I comment out plot2, DailyVolume will update per tick.
If I include plot2, DailyVolume will not update per tick, but rather freezes in time until I re-verify the code.
DailyVolume can be replaced with the Last quote field, and produce the same non-updating results.

Is it something inherent within quote fields that doesn't allow the value to update?

Try adding:

value99 = ticks; // Required for all RadarScreen code to update very tick

to your code and see if that helps.

I currently do not have any VALUE=TICKS in my code, but the value still updates per tick in the regular session, just not in pre-market.
I will give this a try come monday morning.

Thanks for the suggestion!

nfgrufio,
Try to change the default session to premarket.
Go to File > Preferences > TradeStation Desktop > Session > Stocks�Custom Session�your Premarket Session.
This is also important if you want to perform a Premarket Scan.
Need a restart for Tradestation
Hope it helps
