General query

Hello First of all thank you so very much for your kind and timely responses .it's making study understanding easier ..so thanks alot I just have one general understanding question that for the sake of simplicity can we say that if we have decided for future contracts to buy now sell later ...so in the same question if they ask option also w Can we directly write buy now sell later ...as bcoz we decide same strategy in futures !! Can it ever be other way round ..
