So if I'm understanding this correctly, it selects (up to) MaxDatapoints results, and then filters. Is there a way to query a specific number of C trades?
In testing out some of the tick queries, I get far fewer than the MaxDatapoints I specify. For a random day of Google:
HTD,GOOG,1,1 !ENDMSG!,
HTD,GOOG,1,10 !ENDMSG!,
HTD,GOOG,1,20 2018-02-28 17:30:44,1105.81,100,1874094,1105.04,1109.35,15821,0,0,E, 2018-02-28 17:30:23,1106.19,200,1873993,1105.04,1106.19,15819,0,0,E, !ENDMSG!,
(same two results for 50 and 100)

I get this same behavior when using HTT, querying from 000000 to 235959 within a prior day.
Our assumption was that a MaxDatapoints setting of 1 would be an easy way to indicate if any trades happened during that time period, but it seems to be very unreliable and often returns 0 results even when many ticks occurred during the queried time period.
Any suggestions?
