Good evening. Help me find at least one (I haven't found any on the Internet) Expert Advisor based on Fibonacci extension with open source code please.

I'm trying to understand objects, there is an example in MQL4 Reference Manual where pressing a button (pressed/unpressed) changes the picture. The button has two states. So my question is how to make a button has, for example, 3 states or more? I want for each state of the button its own picture. If it is impossible to do this with this function, then what function to achieve the desired result?

//--- установим картинки для режимов On и Off
ObjectSetString(chart_ID,name,OBJPROP_BMPFILE,0,file_on)
ObjectSetString(chart_ID,name,OBJPROP_BMPFILE,1,file_off)

//--- установим, в каком сотоянии находится метка (нажатом или отжатом)
   ObjectSetInteger(chart_ID,name,OBJPROP_STATE,state);

Is it like `? Pressed, half-pressed, half-repressed?

How is it `? Pressed, half-pressed, half-repressed?

Half-pressed :)

Slider on 9 positions) I realised that when pressed it became light yellow, when double pressed it became yellow. But this is not a standard button.

Seriously? So hard to understand even if you read further about the desired result?
Every time you click on a picture, the picture changes. For example 5 pictures, each picture will change every time you click on it, and so on and so on.
Just OBJPROP_STATE was just right, if you wanted to change 2 pictures in a circle, but over more than two.

It's hard to understand what's going on here. We have to explain everything to everyone.

Possible solution: create several OBJ_BITMAP_LABEL objects one by one. Clicking on the first object deletes it and creates a second one in the same place. After the second object, a third object is created. For both OBJPROP_BMPFILE modes , you load the same image and do not track the state of the click, but track the name of the existing object. This name will tell you the current state of the button.

Thanks, I'll give it a try!
