implementing multithreading

My suggestion is to implement multithreading and let the API be thread safe, particularly when it comes to MarketData.GetSeries() it can take a very long time to load the MarketSeries, and it would be really nice to be able to use asynchronous downloads.

Dashboards and screening software in general can suffer a lot from loading times, thus limiting and slowing the development process.

cTrader is nowadays the best platform in terms of flexibility , it's a pity.

Thank you for your kind attention

Sincerely
