I would love to hear from Paras and see what he thinks. When I first made the post I had only seen them on AMZN, but since then I see them on just about every ticker I trade (blue chips) and on nearly every day. I agree all data is important, but the effect these orders have on the tape is really terrible.
They will run in a constant stream like that for minutes at a time and all at the exact same price, and so if price is trading near to this price you get the effect Martin is talking about, and the tape will flash back and forth from above ask to below bid and it makes it impossible to tell what is actually happening. If I pause my recorded
I would love to find a solution that doesn't eliminate data, but the removal of single shares has a minimal effect relative to the negatives that these orders bring.
Also, these orders do show up in sim as well, so if anyone wants to see them these day's for sure have them: 8/22 -AMZN, 8/24 and 8/25 -NVDA, 10/25 -TSLA.
Just watch the first 2-3 minutes on any day and you'll see them. +Here is a clip of TSLA on 10/25, the orders don't stop until 9:32:16. (Please excuse the video quality)
