BrokerHistory2: Increase Ticks to 17,000 or higher

Hello,

I decided to start a new thread before I derail the other one further.

Executive summary:
* I would like the maximum allowable ticks per BrokerHistory2 call to be increased from 300 ticks to 17,000 ticks or higher.

Rationale:
* The Ally Invest API allows my plugin to download up to two months of historical data for a single asset with a single request, whether I use XML or JSON. (JSON is faster, but I did not implement it yet.)
* NYSE hours are 9:30 am to 4:00 pm, 6.5 hours per day.
* 2 months of data is about 16,900 or so ticks. We can round up to 17,000.
* Ally limits requests to 60 per minute. With this approach, I cannot run out of requests if I am too busy getting data.
* Finally, if I use the below test script, the 1 month and 2 month data grabs work, and the 3-month fails.

Attached is the script and its outputs.

We will probably implement a brokerCommand call for setting the size. You can then set a million ticks if you wanted.

This would be good. I look forward to it.

Thank you, This would be great for long term strategies.

Strategies should not be afftected by this feature. But it may or may not improve how quickly a given plugin can download historical data. It’ll certainly help with both of my plugins!
