It would be great - as most people on QuantConnect are retail investors - to be able to trade the recently introduced micro emini. Is there any plan to introduce them? 

One can obviously use the standard e-mini for backtesting (longer data) and then switch to the micro emini for trading live in Interactive Brokers: notional accounts can be 1/10th of what needed for standard emini.
