In the past several weeks, I have put on several SPY iron condors and/or credit spreads in the March 18th expiry, giving me quite a selection of short put credit spreads and short call credit spreads to mix and match to improve probability of profit. I think I can fit one more in here before the remaining time to the March 18th expiration just gets too short to play with (I generally don't like to go shorter than 25 days for these layered on setups; the "expected move" zone constricts such that sides are more subject to being tested in light of ).

SPY March 18th 175/179/200/204 iron condor
Probability of Profit: 64%
Max Profit: $101/contract
