I noticed while following YM today on TradeStation that the tape would show buys and sells with mixed colors, as in this picture:



Note that on this tape in the right hand column there are prints on which the price is colored green (usually a with green background and a "+") yet the number of contracts is red. I thought a green backgroud with a plus meant the sale occured above the ask. But how could a sell happen above the ask (assuming the red contract count means a sell).

The reverse happens sometimes--a red price with a "-" and a green contract count.

Can someone tell me what this means?

Also, there are many white numbers and sometimes the white numbers appear with green or red prices. What does this mean?

I never see these kinds of oddball color combinations on the ER2, NQ or ES. Red always goes with red and green always goes with green and there is no white. Since YM is CBOT and the other are CME is this an exchange thing?

Either way, I'd simply like to know what these color combination mean.

Thanks.

Never mind. I figured it out. The white on green or red quotes are a TS feature which is supposed to show a "trend." Apparently it doesn't work very well because those are some pretty weird trends. This feature can be turned off and once you do the color mixing disappears.

Color merely show if the tranaction was at the bid, ask , or between. Yes, you can change/eliminate the colors. The + or - merely shows that the transaction has changed direction.
