Often, The MM's use the numbers to bait the public into trading a particular direction.
ie: you see 999 pop up on the ask and then the rest are all 50. Some sell thinking a giant order is in place. Not always the case. So pay attention, but do not try to analyze it much. The MM's play with different number sequences with buys and sells too.
And the MM's also signal to each other utilizing particular numbers. MM's shift shares back and forth too. Very unregulated and suspect at times. Especially with the OTC.
So place your bets. A few decimal places will not matter much next week, imo. We head much higher.
I am not flipping any today. Holding all for the news.
