Trade 40-100 days from expiration.Quote from asap:
no. do not use back month for swing trading. back month have huge vega risks which is far riskier than theta.
in addition front month trade with thinner b/a spreads which make them far better trading vehicles, expectancy wise.
if theta is a concern then an itm front month might be used, which basically provides close to 100 deltas without any gamma or vega exposure.
dont trade back month options unless you want to trade vega (option implied volatility). there is even more, especially if looking at leaps, but i wont go there, at least for now.
Yes, as asap pointed out, LEAPS have huge vega risk.
