"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

Data and Content Support » identifying weekly options vs others Jan 19, 2023 11:30 PM (Total replies: 0)

Hi, is there a way to identify options that are weekly vs the regular monthly-type or LEAP options by their symbol name? Thank you


I was looking for clarifications on the rate limiting for historical data requests. In the post describing this, it said whenever you make a new history request, your number of active requests is increased by 1. Every 1/25th of a second (40 milliseconds) this number decreases by one. As long as you don't exceed a rolling average of 50 history requests per second, you will avoid the "too many requests" error. In other words: time your requests such that you do not exceed 50 per second."

Does this mean I can make 50 new historical requests per second, even if the previous ones have not finished? Or do existing historical requests count in this 50 count as well? For example, if I have currently 15 historical data request ongoing, assuming they don't finish soon, am I limited to 50 new historical requests or 35 (50-15) requests in the next second?
