the problem with this option is that i find that sometimes i buy an option that reaches the value but it doesn't make any money such as i buy a call expiring in sep 29 at 2890 and th market is 2895 so if i was holding a future i would make 250$ but holding the option can result with -500$ did i explain it well?I suggested you trade just the ES options without the Future. There is no SPY future, it is an ETF (Equity). The point is that if you just trade the option, your risk/P/L will be similar with a smaller margin requirement and you can reduce the per point risk with lower delta options,
500 Share of SPY=1 ES Future so the risk size is much less on SPY.
