B9 BarsRequest returns far more data than requested

[RanchoDinero]

There are some scenarios where I want to grab just a specific slice of data.

You can use the example code from the help and ask for just a 60 minute set of minute bars from any given day. I'm getting about a day's worth of bars even though I'm only asking for an hour. Which is pretty computationally wasteful for both the API and my code because I have to wade through and find just he data I need and you create a lot more objects than I asked for.

Same problem for me.

The bar request returns an entire day. And because I need 1 tick data bars, the loading time can be up to 10 seconds on ES for example.

However, it was already the case (for tick bars) with Beta 8.

If you specify Days (e.g., Time) in your parameters, it will return at minimum one trading day for caching reasons. This is the same as a Chart.

If you only need a subset of bars, use the "bars" parameter in your bar request.
