$SPX High Price

[Rla1js]

I use high(0,inv"D") to get the day's high price for $SPX on an intraday chart after the regular session starts. While the chart shows the correct high price, it seems the efs does not get this price until about 9:50EST or so each day. The close seems to work fine. I'm using real-time data.

Tech support said it was probably an efs problem since the chart appeared correct.

Thanks.

Today, using the same statement for the opening price, the efs value was wrong until about 10:20am EST. After that, it had the correct value. Thanks.
