[amibroker] Re: how to compare slope

In your post you say you want to COMPARE slopes.  If you are really comparing, you need to calculate the percent change over time.  That is you need to normalize the price of the stock to some constant number - say 100 - as in percent.

The reason for this is that a one point change in a security priced at 10 is 10%.  The same one point change in a 100 is only a 1% change.  Yet in the calculation below they would have the SAME SLOPE.  Not good.
