I have an educational video on Double Calendar Spreads that starts the position with a PUT spread below the money and a CALL spread above the money. 1. Is it true that the PUT calendar spread and CALL calendar spread has the same risk/reward cruve. Even if they are above the money or below the money? 2. Would it be better to just use CALL spreads since they would be less likely to be exercised early than PUT spreads? I plan to trade these on the QQQ and IWM.
