I am new to QuantConnect and am trying to build some basic back testing.  What I would like to do is test an algorithm that I have built outside of QuantConnect.  Basically, I am sending Candle sticks into my system and getting out a probability / trade outcome.  

This becomes a buy or a sell order. 

Is it possible to pass into the backtesting tool (in python) a specific trade?  i.e. 11/1/2017 - buy EURUSD at 1.3244? 

Ultimately, I would like to iterate over an array of buys and sells to see my accuracy of predictions, but if I can figure out how to make a specific trade (either long or short), that would be great.
