Hi,

You want to look at how brokers are made. here are some examples https://github.com/mementum/backtrader/tree/master/backtrader/brokers

then feeds in here : https://github.com/mementum/backtrader/tree/master/backtrader/feeds

and stores : https://github.com/mementum/backtrader/tree/master/backtrader/stores

In all of these links there are examples of how to use live trading for Oanda or other providers. you can inspire your work based on the implementation of the latters.
I hope it helps.

Probably it is quite expensive and therefore rarely used platform, never heard about it during my trading journey.

Common platfroms for such US brokers as Centerpoint. Also it using for prop firms. https://www.sterlingtradingtech.com/
