At last i will release this tool. Last time i wasnt sure that should i release it, but now i will.

1st. Coded by me.
2nd. Dont spread this over the internet ( Youtube etc. ) If you dont want people to know it.
3rd. Triggered by pressing F

There is a GIF in that WinRaR folder which will help you to use it. (Because lack of frames, it wont show all because the tool is too fast.)
It will press trade, unselect the item, and will press trade again.
