Maybe if you move the lines with mql, an example from my practice:
Pure mql, no dll or anything
The code is exactly the same in the two examples
I have this problem, all functions to access time sessions and indicators(CopyLow, CopyBufer, etc.), always return -1, deleted history, updated quotes did not help, what can it be?
In-house or in-house DND and redraw on MouseMove event while pulling.
I can't get rid of lag 100% of course, but I can get rid of it 99%.
Thank you, through MouseMove, it really is smooth.
And in what way does MouseMove essentially differ from a millisecond timer? At that, the parameters MouseMove (x, y) are not used.
Myself I do not understand a basic difference in comparison with timers. Probably, developers will explain.

Yuri, this must be in MT4? In MT5 it won't work so smoothly - there seem to be many new entities/streams introduced there, which the terminal synchronizes including when drawing.

Through mouse events it is smooth exactly in MT5.

I have mouse event video on two platforms. Smooth as long as there are no calculations in the code, if there are calculations like mine, then smoothness is lost

Yes, noticed the MT5 slowness on the video. Most likely the calculations on MT5 are heavier.

No, most likely a slightly different graphics processing algorithm. No work lags on mt4, but there are problems with five. It is especially noticeable when working with multi-window graphics.
And how is MouseMove fundamentally different from millisecond timer in this case? I don't use parameters of MouseMove (x, y). I assume that smoothness is due to a small number of graphical objects. For example, in MetaTrader 4, I looped a script and it somehow worked even faster
MouseMove(x, y, key) parameters are used. The cursor position and mouse click are determined, the main line is moved by mql, not by the capabilities of the terminal interface, i.e. the program monitors the position of the cursor relative to the line, not the line movement. Simultaneous movement of lines is provided by the fact that the coordinates of the main and dependent lines change synchronously.
Yuri, this is probably in MT4? In MT5 it will not be so smooth - there seems to be a lot of new entities/streams introduced, which are synchronized by the terminal during drawing as well.
No difference, it works the same in MT4 and MT5.
