fivecents
my understanding on Ameritrade streamer, When red apppears on a number in a bid, means the # is smaller than the previous #.
When green appears on th # ,on the bid, this means the # is higher than the previous bid #. Same goes for the ask.
The white I'm not sure about.very seldom do I see the white on Pink or OB, basicly it's showing you the direction of the move, in case you were to just turn on your streamer & was wondering which direction things had just moved , you would know.
Go GTEL....
