Near the bottom of the page, you will find table of the Top Movers. This shows what currency pairs have moved the most in the last day, the last week and the last month. Here is the latest example:
Traders use this information to get a quick gauge of which markets are moving the most. A look at this current table shows that the biggest moving pairs today have all included the GBP. Since all pairs were moving up, this means that the GBP has been getting stronger. However, if you check the Weekly and Monthly numbers, you will see that the GBP has been weak. Some traders will interpret this as a move up in a downtrend and look to take advantage of this information by looking for selling opportunities on the GBP. Naturally, they will want to confirm this bias on the charts, but trading with the momentum allows one the possibility of being in on some of the big moves that the FX markets are known for. The Top Movers table is an easy way to identify that momentum.
