Whatever you trade don't trade margins
May I do not get your point. Do you mean: Do not trade on margins, means I use all my money in the trading account on margins to take the highest risk and as many future contract or short options I can.
Or do you mean not to use margins in trading attoll?
If you meant the second point then I highly must disagree with you. Depending on the broker and in what place you trade, margins in option and specific hedge trading is most common and absolute normal. Most simple example: Put or Call credit spreads which reduce the margin needs in the trading account. Of course, not all broker offer this, so you have to talk with your broker about this specific point as you talk with your broker when you want lower turn around cost when you trade higher volumes.
