Tran Nhat Minh :

Hello everyone, can anyone help me with any method to group one object that positioning relative to a chart (Horizontal Line) with another that positioning relative to a security window (E dit) as shown in the picture?

What?

What?

I have an idea to use ea to create a countdown timer pending order. There will be an edit object to inform the countdown time, this object will be attached to the horizontal line and it will move according to the horizontal line, but I have a problem that I don't know how to get the price coordinates of the horizontal line to change the coordinates of the edit accordingly.

Yes i wrote that part wrong, the real problem is that i can't get the x,y coordinates of the horizontal line to fit the edit object but instead there is only function to get its value coordinates

Oh, thank a million, the idea seems so simple but I can't think of it :))

Your idea is to get the value of the Y_DISTANCE coordinate of Horizontal Line returned by the OnChartEvent function (in CHARTEVENT_MOUSE_MOVE), but there is a problem that when Ishrink or stretch the chart (CHARTEVENT_CHART_CHANGE), that value does not return the correct y coordinate of the price bar.

Can you have any other idea that I can get the Horizontal Line's Y coordinate, or convert the price, time coordinate to x,y coordinate for example
