I know that comparing to being long on call, bullish credit spread gives a credit, an 'insurance' in case the underlyer goes down (at the same token limiting the profit), less sensitive to price, time and volatility. A good spread should give 63/35 profit/loss. Are there anything else I missed? When I go long call, I usually look at 3-6 month expiration (and depending of the market, I usually get out at the next resistance for not losing too much in theta). For a bullish credit spread, should I look at the same expiration, i.e. 3 to 6 month contract? TIA Cheers!!
