please help explain this

I dont know what to think.. Is it market manipulation by a trader? Is it market movers who made a mistake? Is it a default trade by the system? Its kinda of confusing to me but I have a feeling the price will shoot right back up again...

Yet another .... Mommy why is the sky blue topic.

Fractional shares done on most venues are rounded to 1. That is why critical data may be in the prints around. Glad to see nobody read the Finra link. Conspiracy theorists just prove that even paranoid schizophrenics actually have real enemies - or lack a Google connection.
Tell me about the prints around it.

Would a brokerage like Schwab be a FINRA TRF?

Venues report to the TRFs - not brokers. Mostly dark pools as they don't have their own reporting systems.

I often see a stock in after hours dropped tremendously but when I look at the time and sales it says only 1 share was sold .. What does that mean ? Im shorting a stock called MAMA at 4.24 and it has dropped to 4.04. But when I checked on time and sales it was only 1 share sold at that price.. So what does that mean and why does this happen so often? Thank you for any help and no im not looking for insider information...

It means that watching level 2 or time and sales is a wot because not all orders will appear. This is what the chart is for...why look a a row of numbers when the visual is done for you?

It's the equivalent of reading an earnings report...they can manipulate the numbers to a degree that its useless information. TA and price action is the only thing you can trust imo.
