If Ninja dos not support options trading (spread). How could i calculate my backtest results correctly? i have a couple of strategies in range 4, generating 70% per month (backtest) performing in the lowest time of the market. but it is useless in the real life. and is not because "slippage". it is the spread: Two ticks lost, for each one operation, into 30 operations per day its a lot of money.
I am Wrong? Some advices?
