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:
