Hey Jerry,

Good to hear from you and glad to hear your trading is going well.

Not sure that I have heard the term strength meter but I can see how the US Dollar Index could be referred to as a sort of strength meter which shows how strong the Dollar is in relation to all currencies.

So basically if you were looking at the EUR/USD for example then this would obviously tell you how strong or weak the US Dollar was in relation to the Euro.

What the dollar index is designed to tell you is how strong or weak the US Dollar is overall against all of the major currencies. With this in mind many traders will start any trade involving the dollar by analyzing a chart of the US Dollar Index. This gives them a feel for the direction of the US Dollar overall. If they feel that the overall direction of the Dollar from this analysis is weaker for example, they can then take this information and find the individual currency where they feel the US Dollar looks the weakest and sell the dollar and buy that currency.

Let me know if that is not what you were looking for.

Best Regards,
Dave
