What is ur datasource. I find DTNIQ to be causing heavy cpu cycles.
the same scans that i was running last week is now slowing my system.
if i shut down the connector and run it connected to a different
datasource like IB, it is normal.
If anyother are having same issues with DTNIQ, i would appreciate
response because i am going to complain to them now.
For the last 2 days, it is so bad that i cannot use the DTN data
source at all. Maybe the 75 dollar savings compared to esignal is not
worth it.
In terms AB optimizations,
1. i run 2 scans, i run a EOD scan to filter out potential candidates
adn put them in a watchlist. then i run a realtime scan on the
watchlist to get me my results. obviously, loops would add to the
execution times.
2. i have noticed that repeat scans on the same formula returns data
quicker. i guess, the first time, it has to backfill lot more. so i
start running my realtime scans before 9:15 am so that by the time
the market opens, the scans are runnign faster.
Finally, this week DTNIQ is a resource hog. really big time.
