Can you post a screenshot of NNDM at 8:42 am on May 20. (I am trying to find out the exact timestamp it plummeted in seconds.)
You can also check the time and sales to see the seconds data, however are you sure your time is correct? Looking at my chart it looks like it traded HOD at 9:50 am ET before dropping. The time you are looking for, at least according to my times and sales is 09:50:17 am ET, the start of the drop.
Wouldn't you be more interested in a times & sales window of NNDM price action involving the duration (around 0842am) on May 20th ??? wrbtrader
