Correlation, in financial terms, is the numerical measure or relationship between two variables. (In this case, these variables are Forex pairs). The range for the correlation coefficient is -1 to +1. A correlation coefficient of +1 signifies that two currency pairs will flow in a similar direction. A correlation of -1 signifies that two currency pairs will move in opposite directions 100% of time. A correlation of -1 indicates that two currencies will move in the opposite direction 100% of the time. Finally, a correlation zero signifies that the relationship is completely random.
What is the current trend of each currency? Is it bullish, or bearish? Which is the current trend strength? If the currency is plotted to the right, it will be bullish in its trend direction. Its bullish trend strength will be stronger if it is closer to the upper right corner. If the currency's trend direction is bearish, it will be plotted on the left. Its bearish trend strength will be stronger if it is closer to the lower left corner.
Some products could even produce data which is not consistent with the original concept about currency strength. Some applications use smoothing filters, such moving averages, and some others apply filters (e.g. RSI or MACD. Forex traders could be misled by false signals or lose streaks if they add filters to demonstrate currency strength.

Our meter takes more pairs into account and calculates an average gain or decrease over a few time periods to determine the overall strength. It does not calculate a price as an index, but rather gauges strength on a numerical scale.
