Hi everyone, today I came across an email regarding the Vertex indicator. A gentleman wrote to me saying it’s impossible to make this indicator non-repainting (NRP)—that he had tried many times without success. And he’s right; the indicator is poorly designed, so it won't work without rewriting the entire startup sequence. However, you can always get as close as possible to the maximum—roughly 99.7% to 99.9%. We have to realize that it is an oscillator, and a 100% non-repainting version simply doesn't exist! Why? Because if the broker can't keep up, data overwriting occurs, and every indicator reacts to that—which is why 100% isn't possible. Regarding the index—using index 1 instead of the current 0 yields 97% NRP (provided the logic is sound, though in the standard Vertex, it isn't). A robust snapshot method can achieve 99.7%–99.9%; I use my own locking code, but I had to rewrite the entire startup routine. Image 1 shows the Vertex with 97% NRP, while the second shows the locked version with 99.7% NRP.
EDIT: You can see it better here.
