I am trying to get 10 bars of 5 minute history from a point in time forward, and I can't get it to work.

Here is my request and responses - I am specifying the begin date/time only:

I am specifying only a begin time and bar count. What I expect in return is:


#HIT1,2018-08-27 00:45:00,2883.50,2883.25,2883.50,2883.50,37031,51,0,

I can only get it to work by specifying an end date/time of 2018-08-27 00:45:00 or by specifying both the begin date/time and end date/time.

My 'begin date/time only' request returns bars with timestamps starting at 16:35:00, which is the bar current at the time of the request (16:39:00)

What am I doing wrong?

Thanks,
-Jake

I don't believe there is another way to do this.

When you don't specify an end date/time, the servers use the time of the request. The servers also always work backwards in time to service the request. As a result, the servers simply find the first X datapoints that meet the criteria of the request and then stop processing data.

You will have to calculate the end time instead.

I was afraid you would say that :(

Calculating the end time is going to be tricky.

Can you guys clarify the documentation to indicate this isn't possible?

I'll add it to my board. Maybe I will add a FAQ specific to history that would cover this kind of thing.

Sorry for the inconvenience.

Tim
