Off the top of my head, probably close to 30 instruments charted simultaneously, plus a heat map, plus a watchlist window with many dozens of instruments, though only a couple dozen at most in one watchlist. Truth be told, some of those charts were just checked in the morning and then not checked again until the close. So I'll have to deal with opening those charts manually when I want to look at them, then close them. And for others, I can just monitor prices in a watchlist, and click on instrument to chart as needed.How many chart windows did you initially have? And at what maximum number of chart windows does TOS work fine, without lag?
I reduced to ~12 instruments charted simultaneously plus the watchlist window. Lag reduced to acceptable levels. I noticed that if I reduce charts further, I can get to no noticeable lag.
Again, the lag is only in TOS, and I was plotting similar # of charts in TWS without any noticeable lag. Though TWS was terrible for chart drawings, so I did those in Ninjatrader. But I do those drawings in TOS, so I am asking TOS to do more than I was asking TWS to do.
