How do i calculate the difference in percentage??

Hi,

Can someone tell me how do i measure the difference in percentage between any two points on metastock price chart?
i mean if make a trendline between point x and y how can i make metastock instantly calculate the difference in percentage?

Thanks
Abe

Any % is simple ((a - b)/a )*100 but locating 2 points in a trend line is possible but difficult.For that you have to have some idea in the code language of MS.

Thanks for your reply.

But i mean suppose i'm watching a price chart and i want to see how much this stock declined since it reached it's peak till now . is there a way in metastock to point two points a and b and calculate ( (a-b)/a)*100 ? i've seen this option in other trading software and couldn't find it in metastock

Thanks
Abe
