Error: Pacing Violation

[TAJTrades]

I got an Error Message in the Log tab:
Pacing violation: more than 10 API calls of type "Heartbeat" in 150 seconds

What does this refer to? And how can i fix it?

Thanks.

I was working on an EOD Stock Screener utilizing Market Analyzer. Only connection open at the time was KineTick End of Day (Free). There were about 3500 Symbols in the MA. The computer started out with about 85% CPU Utilization. Then something happened ( I don't know what) and the Utilization dropped to 10%. Mystery. Hardware Bottleneck? Market Analyzer code flow? Aliens?

BTW: Zero complaints running all the ES Charts.

Hello TAJTrades,

Thank you for your post.

"3500 Symbols in the MA"
This is guaranteed to slow any computer to a crawl. Please try reducing the number of symbols in the Market Analyzer until the performance improves. You would likely only be able to load a hundred or a few hundred symbols if you want to see a drastic improvement in performance.

Are you saying that I am overly ambitious or you guys can't keep up. lol

Would the Market Analyzer be the best option for an EOD Stock Screener? Or have I over looked something?

You would have to test to find that limit for your PC. After testing on my end, 80-100 symbols will start to slow down my installation significantly. This may be different for your PC, however, 3500 symbols would be too many.

This would be the best option.
