what is a simulation? on E-MINI?

Simulation is like paper trading. For e-mini, you're basically watching/virtually trading the E-mini which is the S&P 500 mini--contract.It's a futures instrument as opposed to equity or index like the actual S&P 500 or an ETF (Exchange traded fund).Net/net. Simulation on E-mini allows you to virtually trade the Emini futures contract and is available from many futures/commodity brokerages.If you have other questions, please let me know.Hope that helps!
