I have. However, as I spend well over 50 hours a week starting at charts, I need to use black backgrounds as to not melt my retinas. Black charts are much easier on the eyes when stared at for extended periods of time, especially in the evening.

Unfortunately, you can’t simply switch from a black background to a white BG on TC2000 as most of the trend lines & annotations (the colors that standout on black charts; white, yellow, light blue, etc..) do not change accordingly & as such, become lost against the white BG. I also have the vol at price bars as well as my moving averages, volume, & some other indicators intentionally muted down in intensity as that provides for a cleaner chart image. As such, I can increase the brightness when needed, such as during video recordings (solely for the benefit of others with monitors that aren’t very clear or bright) although I can see them fine on the high-resolution monitors that I use.

I have to say that I’m impressed, not happy but impressed, with the resiliency of the FAAMG stocks but also watching the rest of the market (or more accurately, THE stock market as QQQ is not a very diversified index), rolling over on the intraday time frames after breaking trendline support, then price support & then failing on the backtest of those support levels (10-minute charts).
I recall a similar disparity in the performance between a handful of the market leading stocks & the rest of the stock market back in late 2007 & at a few other points in time & it didn’t end very well (if you were long, that is).
