I have a basic question, sorry I am new and it might seem like a silly question to few people here.

I have a UI where I can enter parameters lets say TSLA (TESLA), buy price and quanity for June 7th 2018.

Now These UI parameters are passed to a webservice. In this web service, how can I take these parameters and run a specific algorithm on quantconnect platform

I have seen quantconnect UI, where you can write algorithm and run it there and send to live broker. But that is not practical, I want the user entered parameters in my application to be passed to this algorithm that can be run on quantconnect platform -> live trading broker.

Please advise. Thanks a lot.
