%%Can you be more specific? What is a block trade? TWS Time and Sales displays all the sale conditions associated with each trade which can be used to identify where and how trade was executed. I know many traders have two TnS windows with one of them only filtering trades exceeding some threshold, like 100k shares. I don’t think TWS has this feature but not sure.

I haven't found SCHW block trader indicator , 2 minute search;
15 minute charts , good volume could figure something out.
Its in Time + sales also but i seldom study that......................................................................................
%%So if you set some criteria in Times & Sales like wanting to see executed orders of 20k and up ..........
If the answer is yes, can you please post a screenshot ?
