Oleg Bondarev:

The tick indicator.

What does the other one show? Why are they diverging?

How often do they need to be aligned?

What does the second one show? Why do they diverge?

There isn't a second one yet. The principle is the same, ticking, only with a filter. Alignment will be as soon as the pattern appears on the one I posted. Something like wave work (bottom appeared, we align to it, peak appeared, we align to it).

if you combine them into one, you can add a deviation

   x[0]=b+"отклонение";

and depending on where you want to align, the deflection will be (+) or (-).

The deviation will not be constant. I thought about moving the line with the mouse, but apparently it's not possible. Sad(.

No way with a mouse...although freelancers can do a mouse deflection adjustment, but for a fee(

If I was sure that the system would work, I would have ordered it right away.

I did not do it, or rather I did not search for it in the subwindow. In the KB I have laid out an example of clicking on the main window bars and displaying information about the bar - you can look it up

I have made an indicator for experimenting with buttons - I checked if the buttons move the indicator line

to see that the indicator is moving drop a horizontal line into the indicator subwindow ... Pretty cool thing to do ))))

Igor Makanu:

you need mouse click coordinates

There is an easier way, you move the Trendline to the right place and behind it the

something like

        // получаем точки
        string name; double b;
        int i, j=0, n = ObjectsTotal();
        for (i = 0; i<=n; i++)
        {
                name = ObjectName(i);
                if ((ObjectType(name)==OBJ_TREND)&&name==ID)
                {
                        tX[0]=ObjectGet(name, OBJPROP_TIME1); pY[0]=ObjectGet(name, OBJPROP_PRICE1);
                        tX[1]=ObjectGet(name, OBJPROP_TIME2); pY[1]=ObjectGet(name, OBJPROP_PRICE2);
                        break;
                }
        }
