Performance ??

[nedibe]

First Nice to see Robi onboard.

I would like to know what are the limitations on the active x?

how many stx can I subscribe to for quotes at the same time and how many stx can I subscibe to in time and sales without slowing down data recovery?

I guess you guys did some testing on it.

Thanks,
Nick.

Performance

nedibe,

Thanks for welcoming me. I would say that performance is adequate, but not great. I would say that currently the upper limit is a 1 minute tick for around 250 stocks, but you can definitely track quotes for 1000 symbols at a slightly broader interval (5 minutes). Keep in mind that this control was designed to improve on very limited DDE functions and is great tool for the price. As it evolves and is used in more situations, performance will improve. I am looking into using more XML-based features that should help.

I would suggest creating a second instance of the API object to handle data for time and sales since it is a different server. They may or may not improve efficiency, but worth a try.

Please keep me informed on the limitations you experience so I have a frame of reference to improve upon.
