Gap Fill Indicator

You need to store gap prices in an array, then check, each bar, if any of them has been filled or not and, when they have, set them to 0 (and maybe shift all array elements one place, but it’s not mandatory) to skip checking them again.

It will take some time to code it. I will make it as soon as possible 🙂

Adding an indicator to the price window works for me both on v11 and on v12. The indicator has to exist in the list first. So when you create it first time around and it isn’t in the list yet, it appears below, you save it, then it’s in the list, and then once it is in the list you can do as the video.
Did you mean you get a panel below each time, having tried several times, or did you mean you only did it once for creation when it is not in the list yet and can’t do as the video? If even when trying again picking it from the list, it doesn’t work, then there might be a problem specific to your platform, and you would need to send a technical report from your platform to PRT (CTRL+M). It works for me on v12, so can’t reproduce the problem and help further as fellow user.

Ok, there might be a problem here indeed, I started from scratch again, imported it rather than create and copy-paste, but it didn’t change. The only real difference I could think of, is that I had added it as “favorite” (the yellow star next to it) to avoid scrolling down the indicators list to find it. So just in case, I tried without adding it as favorite, and indeed it made a difference, I am now having the same issue too, when not favorite it doesn’t get added to price, but when added as favorite first, it does.
Good enough for me to highlight it as a v12 bug to Nicolas. In the meantime, you can try adding it as a favorite in case it helps temporarily in your platform too, until they see if they can replicate the issue, and fix it.
