Louis,

Bid/Ask Spread, IV, Theta, Beta, Gamma, life cycle of the time decay. Don't trade options until you have internalized what these mean to your profits. Otherwise, it would be like trying to play chess without knowing how the knight moves --you will get slaughtered. Profits are in the marginal areas. Do some simulations and see how sensitive the profits are to the cost of a trade.

I have strayed a bit far from the purpose of this forum at this point. You would be better off looking for more specialized places for these basics. I learned by using the option tools at thinkorswim, and living through the life cycle of many trades. Once you understand options, futures will be a piece of cake to understand --though much riskier in a significant news event environment.

Best regards,

Dennis

Hi Dennis,

What do you mean by option having a heavy « overhead »?

I had the plan to buy options in the money when I get a signal from my system. Wouldn't that be a good plan? In what futures would be better than options?

Thanks,
Louis

Louis,

I trade stock, options, and futures.

Futures are leveraged. That means that you are essentially borrowing the money to buy and sell an index with a small "down payment". Say you wanted to trade the SPX S&P 500 index ($1381.29 close today). You could trade the SPY ETF for $138.36/share. It will cost you $69,180 for 500 shares and you get $50 profit per SPX point ($34,590 on 2x margin, or $17,295 on 4x day trader margin). You could trade the ES futures contract for about $5000 down payment on 1 contract to get the same $50 profit per point. That is a lot more leverage. With a $100K account, you can do a lot more with futures than stock. However, with leverage, you can lose more than the size of your account --very quickly. Money management and working your way up to more leverage with experience is an absolute requirement. In the US, futures profits are given more favorable tax rates.

Options allow you to have leverage similar to futures and risk no more than your purchase. However, they have a heavy "overhead" per trade.

Each has its advantages and disadvantages and it is best to tailor their use to a particular situation.

Best regards,

Dennis

Would you consider there is more money to be made from futures than from stock?
