I have a similar structure, but I like this 121 fly from 50-risk. I'd suggest the iron, but the call is decent on "forward" microstructure as I suspect we'll be trading under the body-strike. Long SPX 2760/2840/2920 121C from 50.30 is marketable:
Someone sent me this morning's "Steady Options" alert from Kim Klaiman. Kim was trading a partial cover of the 117P body strike of his five-lot TST Sep21 112/117/122 put fly. He showed a fill of 0.20 on five of the Sep21 117 puts. The problem is that the five lot never hit the tape. The time and sales are shown below. I have sorted the T&S descending on time, exp, option, size, price (0.20). The 5-lot buy at 0.20 never took place. Kim Klaiman is using Interactive Brokers' TWS Paper Trader front-end for at least a portion of his trading. The TLT Sep21 117P trade never hit the tape:
So if Kim Klaiman is faking fills via a sim-account, what chance does his subscribers have of being filled on this garbage? Kim is stating that all trades are "traded" ... yeah, paper-trades.
