The multiple 100s are partial fills against a larger buy order at .0020. When they appear in red after a green that means it was a fractionally lower price than .0020 in a paint down attempt.
Often when I'm slapping the ask I'm getting partial fills at a fractionally lower price from those paint down attempts.
You can see the price to 5 decimal place on E*Trade by altering settings but I don't like to do it as it is too confusing for quick trading action.
After 15 minutes, you can check on iHub at Tools / Trades where prices like .00199 would be shown if applicable.
