Hi,

When watching only 1 symbol (AMZN), I observe that ticks are bursting. For instance, I will get 20x '15:44:09' ticks at 15:44:09, then 10x '15:44:09' ticks at 15:44:10, then 30x '15:44:09' ticks at 15:44:11, then 15x '15:44:09' ticks at 15:44:12, etc. The delay can go up to 10 seconds. The delay I am referring to here is the delta between the 'Last Time' field of the quote and the time I receive it on my end.

When watching 1300 symbols, the bursts are spread on a even larger time frame. Delta can be up to a minute (tested at the end of the day. I still have to test at the open...).

Is this normal? (I am not sure what to expect in terms of speed of receiving ticks)

Thanks,
Frédéric

I had delayed quotes yesterday as well. Coincidence?

I'm not aware of any delays but I will investigate.
