Was there a single transaction we can point to that marked the beginning of the 1929 stock market crash?

I understand there were a lot of factors contributing to the crash, including cheap credit, higher interest rates, and agricultural industry struggles. My question is specifically if there was a hallmark significant transaction that caused the panic - like the failure of the most expensive tulip in Holland to sell in 1637 (this is received wisdom so even it may be dubious).

I am not qualified to answer your question, but could you specify which stock market crash you are referring to?

There were three crashes in late October 1929, referred to as Black Thursday, Black Monday, and the final Black Tuesday (source). These would all presumably have different initial sales.
