Currently, Blocks has a code block "Correlation" which I could use to develop a correlation indicator to compare the plots for two different stocks. Has Worden or anyone already created an indicator that does this?

If not, could you create one. I am sure a lot of users would find it useful and it would save each of us having to develop a unique version of it.

Thanks

What kind of correlation are you trying to measure? Is it something that a ratio cannot do?

I am trying to measure the statistical correlation between two stocks (prices).

Correlation is a statistical measurement of the relationship between two variables. Possible correlations range from +1 to –1. A zero correlation indicates that there is no relationship between the variables. A correlation of –1 indicates a perfect negative correlation, meaning that as one variable goes up, the other goes down. A correlation of +1 indicates a perfect positive correlation, meaning that both variables move in the same direction together.

I don't think a ratio would accomplish the same thing. My assumption is that the code block in Blocks for "correlation" is statistical correlation.

Hope this helps.

This will be very helpful.
