The greeks are chinese to me! If anyone can help shed some light on the greeks and their affects on options prices and different strategies, it would be greatly appreciated. Generally I trade OTM Credit Spreads and Iron Condors. I'd like to trade verticals, but based on what some of you have been saying about understanding the greeks first, I thought I post this question before experimenting. If you do respond, if you could provide an example, it would be greatly appreciated.
