Hi,

I read that we can't change symbols in order to work around the 500 symbols limitation for the live feed (which totally makes sense). Anyone happens to know how it works exactly? After unwatching a symbol, is there a delay before we can start watching another?

Also, is there a delay before Historical data is made available? Or is it available right away?

Thanks!

Frederic

Sorry for the chopped title... I submitted the post a little too fast.

Good morning,

I would just say that in regards to the symbol limit, we don't actively police this behavior, but just be sensible about it, obviously if we see a million requests in a minute that is something that might raise some eyebrows, but even then I would contact you first before to discuss before taking any action on our end, unless your usage began impacted other users. There are times where accidents happen and loops go crazy, but for the most part you should be fine.

As to history, tick data is available immediately, as is minute, but daily or greater data is written upon market close, so you may have to wait on daily/weekly/monthly depending upon your needs.

Just one more note on this, you can upgrade your service to be able to receive up to 2500 symbols. It really just depends on what you need out of our data as to what would be best in your case. Feel free to email the developer support group though with any details of what you are trying to do and I would be happy to help advise on what approaches might work.

Hi Tim,

Thank you for the answer.

I really like your policy and the way you enforce it. (My goal was only to learn about the constraints.)

Have a nice day.

Frederic
