Hello All,

I am attempting to backtest a strategy that trades Futures contracts for the Indices. However, when I run my backtest I receive the error that the symbols I am attempting to trade are marked as non-tradable. I would like to be trading the front month contract and only focus on the M, U, Z, H contracts. I have run this exact algorithm with forex and equities and the backtests run fine so it must be some issue with how I am selecting the specific futures contracts. Any help would be greatly appreciated! Also I am not a coder so if there is any mistakes or bad practice you notice feel free to point it out. Thanks again!
