Chart Co-ordinates and Button placement in mql4

 

Hey I created a button using this library <Controls\Button.mqh>

I want it to be in the right corner of the chart so I placed it using this BuyNowButton.Create(0,"BuyButton",0,105,35,205,80); and  BuyNowButton.Move(1090,20);... but now when I open the navigator or market watch the button goes out of the chart... and it does not display in the same place in my other computers.. Please help...
