optimal way to track 200 symbols

[nedibe]

I want to keep track of 200 symbol.

It seems that the active x is not retreiving the values fast enough.

I subscribe to the 200 symbols and then I retreive my bid or ask them directly.

Should I:

1 stop subsribing and retreive the values directly. I would then lose the ability to react on changes...

or

2 only subcribe and update each time the update event is fired a global data structure. Maybe getting the data directly has a lot of overhead...?

thanks,
Nick.
