How to do this calculation: we have a Price1 which is a permanently changing price, a Price2 and a percentage PER. If Price1 goes down, Price2 also goes down in the proportion of the percentage PER, but if Price1 goes up, Price2 doesn't change.

There are two methods for doing this at a recent thread. Please take a look. The difference is that in those examples any changed price is recorded whereas you want to record it only if it's higher than the previous. That's a minor change in the code.
Please select the method best suitable to your needs and install it in your workbook. Then, if you need help with the customisation, post a copy of the code you will then have and ask for it to be modified.
