Of course, this takes us back to the original post.
And the observation that no platform vendor is implementing this.

Yes.
SQ is workable if I can have access to the Time&Sales pipe from the vendor.

(I am under the impression that...)
ESignal sends complete time and sales ticks down the pipe.

Some data vendors only deliver their data in seconds packets.
Often the data vendor drops >inconvenient< ticks.

Most platforms then bundle the piped data into minimum size packets.
The SQ data engine seems to support seconds sized packets. (Great!)
But does not seem to show all ticks.

TS Global Server drops intra-second ticks and volume, recording only the
last price.
(TSGS does not support sub-minute packets. SQ wins!)

As concerns the creation of my own bars, I am not sufficiently familiar with
SQ to know how.
Do you have a code example suitable to daytrading?
