The green highlights usually give you the indication that these stocks pass the Technical Analysis test

If the stocks are not highlighted green then they don't pass the Technical Analysis test

For the Currently Ready to buy tab, the stocks are highlighted green when they are near to getting filled. All the stocks in the "Currently Ready to buy" tab are less than 10% of getting filled. 

The more dark green the stock are in the "Currently Ready to buy" list the nearer they are (base on the current closing price) to the buy price

For the Channel Breakout trades and Trend Analysis trades tab the green highlight means that they have a good technical analysis. 

Usually you will want to buy the stocks that are in the "Currently Ready to buy" tab because they are closer to being filled. But we show the other tab because some users will like to place trade on stock even if they have more than 10% off high.
