Greetings, I'm new to options, have been trading Iron Condors, spread trades, etc. for a few months now, and have a question: Some people recommend managing the trades by adjusting them individually, others recommend managing "portfolio delta" to keep it as neutral as possible. I've been managing about 12 trades per month just by adjusting delta (selling Vertical Calls if needing negative delta, selling Vertical Puts if needing positive delta) and have done well that way. But is this a viable long term method? Any input you have on managing/adjusting trades would be helpful, or pointing me to a valuable resource, etc. Thank you in advance.
