everything about objects, charts, windows(mt4) and sub windows, buttons, skins, colors, sizes, tables, lines, animations build, mouse use, keyboard use....... everything you can see on the screen, I can automate it, change it, build it for you. If you want a simple 5-6 buttons panel = around 100$, but if you want an interface for a big operational system bot with 1000+ buttons and menus and mouse dragging scrolling, keyboard using shortcuts, graphics building.. full project job = 10 000$+ and it needs long term building. My code is very light and it works as fast as possible. I use my simulators to test and simplify everything I write. A friendly person :)
