Iron Condors are very safe compared to naked puts or calls. You sell an out of the money put and call then buy a put and call farther out of the money and collect the difference in premium. Example Jan 8:

Sell 3800 call and buy 3815 call collect (10.20-7.06) 3.14 on the call side.
Sell 3600 put and buy 3585 put collect ( 12.66-10.90) 1.76 on the put side
Total premium collected is 4.90 or 490.00 per contract and loss is limited to difference between strikes minus premium collected.

490.00 per contract for a one week strike. You can adjust the strikes per your risk tolerance and expectations with respect to capital used. I don't have my trading software up but I can tell you the margin on this is better than on naked trades and return on capital is very good. I usually look to make my trades at somewhere between 80 and 90% probability of success. Last year I had only one condor go bad and I took the loss early instead of letting it go to max. I usually take profit and put capital back to use at around 65% of max profit. In an uptrend like we have had for the past few months I look for a bigger down day to enter so I can get really good prices for the put side and widen the calls for the inevitable rebound.

This is not trade advice. Use paper money to experiment and get comfortable before risking real money. Seek professional investment advice before risking money. Etc, etc, etc.
