Expanding a bt on what Mark wrote, suppose something spooks the market and within the first week the SPX drops 1/4 of the way to your short strike and IV expands a bit.Basically , as I understand with the SPX at 1115 , the SPX would have to move 75 points up or the DOW would have to move 800 points up in 48 days to see a loss or the SPX would have to move down 125 points or the DOW would have to drop over 1300 points for me to lose on the downside. I know I won't get filled at 2.10 , but lets say 1.95. My risk reward is roughly 4 to 1.
I hope to invest $100-150 K in IC's and Calenders in a yr or so, once I learn more. So if I lose 30% - 40% of the $7900 invested now (due to a massive move) I could deal with it. (not to sound like a smartass). I plan to put on 1 or 2 trades a month(10 contracts each) for 1 yr, learn and see how it goes.
Maybe you have $200-300 loss per condor, 2-3g per 10 IC's... and how much if your full 150 K is the pot? Now, maybe you adjust. Buy some more expensive protective legs which might make your entire position profitless? Sell more legs at different strikes, increasing your risk? Maybe these makes things better, maybe worse.
Or maybe you think that it's still a long way down to that short 1000 put and the force is with you. So you do nothing. The SPX heads a bit lower and maybe IV perks up a little more. Your loss per condor is increasing. Still confident that you have plenty of buffer? Did you save some dry powder for the expanding margin requirement? (see IV of 50+ less than a year ago).
At what point do you start to get overwhelmed by the losses? Or do you have the stones to resolutely say that it's not going to break through 1,000 and your misfortune is just temporary (as the market mugs you daily)?
So you had this really wide, seemingly almost riskless buffer. Good odds. Funny thing about odds - if they're 4:1 in your favor, they mean nothing when you're the 1.
I'm not attempting to discourage you from trading. Just suggesting that risk should be respected and feared and no matter what you're trading, AFAIK, protecting your principal is far more important than collecting that small profit. Corny as it sounds, you need to be able to live to fight another day.
Good luck!
