is there an easy way to obtain by code the price variation percentual  [SOLVED]

Hello everyone,

is there an easy way to obtain by code the price variation percentual ( typically displayed a the top of the chart automatically) ? (I didn't find any keyword for that)
It's not so easy to manually calculate it as sometimes it doesn't take the close of the previous day session.. but it use the close of the cash session.... for example with the vstoxx futures quoted at eurex

I need the value in the circle ..

Hello dvdkite,

You can use this code:
100 - ((prevclose * 100)/close)

Please check the attached screenshot.
