Hello support,
why methods subscribe to data feed has Ask and Bid separately? Most of us need both values. If system send it separately is problem to join it together.
Tick includes Ask and Bid values in one object. To onBar are coming Ask and Bid bars together.
But data feeds (include history.getBar..) separate Ask and Bid. It often complicate data processing.
Thanks for improve.

Hello lifon!
Because it's flexible way that allows you to get only the data that you need, thus minimizing amount of downloaded data and improving performance of your algorithms. We currently don't have any plans to change that approach.

Hello support,
I prefer only one bar - Ask High and Bid Low. Time bars is easy to "sum".
Range bars are problem. I make my own range bars from ticks.
Have a nice day
