Someone asked on that 12 million trade was it a sell? Actually the trade was in black not red or green heres the explanation on a level2 on colors

The changing colors on the Bid/Ask prices on Level 2 indicates Market Maker tick movements.

• If the market maker upticked from their last order/quote, it's green.

• If the market maker downticked from their last quote/order, it's red.

If they haven't moved, it's black
