# Percentage change from open

Can I ask, does (Close > Open * .50) mean that price is up one half a percent from it's open?

• I would like to add a % change on the same day requirement to my scans.

One per cent is .01. So a half per cent would be .005.

But, a half per cent of the open would be just a small fraction of the open. So, suppose the open is 100.

100 * .005 would be .5

So, your statement would be close > .5, which is bound to be true.

What you want is

and [close > open + [open*.005]]

So if open is 100, it would be "close > 100 + (100*.005)", same as "close > 100 + .5", same as "close > 100.5".
• Thanks Mark. I am envious of your brain power. I am trading SPX only now and I am working on another filter the help reduce or eliminate a few of the losers. I will use a half percent filter on some and about one percent of some others. Thank you. I'll go experiment with what you gave me.
• It does exactly what I want. Thanks

Another way to express it is:

and [close > open*1.005]

... a little easier to write - just make sure you use 2 zeroes and not one zero by mistake.
• Thanks appreciate it
