Floor Trader Numbers and their usage in trading is very well known. They are primarily used to predict future support and resistance levels, both in pull backs and trend extensions.
The primary value calculated is the pivot, along with 3 support and 3 resistance values.
Knowing the pivot, support and resistance points can help the trader to identify potential entry points and stop loss levels for your trade if your other criteria have determined the direction in which you should be trading.
Part of your daily trading ritual should be to calculate the pivot point and the areas of support and resistance after the close each day for the markets you are interested in. Study the next day's price action in the context of those pivot points so that you get familiar with the dynamics of the market.
