I would like to improve my performance and it seems understanding and using greeks is necessary. I currently trade iron condors and vertical spreads for credits. How I would like greeks to help me : When to make adjustments? Improve return on my capital. At the moment I keep my return between 1-2% per month. I go far out of the money so as to have minimum adjustments. I dont mind making more adjustments and taking some losses as well if I can improve my overall performance Plese explain how to use greeks and post some links as well which are easy to understand and gradually educate myself for higher levels of understanding. Thanks and all help much appreciated.
