Hi gang,
I started running a new intra-day system realtime via
Tradestation 2000i + Dynastore + quote.com. After a
several days of running it, I am getting a disturbing
result. Yesterday, for instance, my realtime strategy
and corresponding indicator was flat the whole day.
Today, after rebooting, I loaded the same exact system
using the same data (except now historical). It
claims to have given me a nice sell signal midday,
just before the nasdaq tanked. In fact, the realtime
signal/indicator are totally different!
Have others noticed anything like this? At first I
thought it might be due to precision errors. But I am
not sure that make sense since I thought the chart is
recalculated each bar from scratch.
Note that Tradestation had been running for 3 days
straight and, moreover, I was doing overnight
optimizations in other workspaces during this time.
Generate orders for next bars is checked. Becktesting
resolution is unchecked.
I am very perplexed as to what I should do. I suppose
I could re-start Tradestation 2000i every 15 minutes
or so. Is anyone else doing this as a workaround to
this problem? Does anyone have any suggestions?
Would this same problem occur in Tradestation Pro?
Confused,
Jack
