Its very easy in this game.

Click menu, then click trading.

Click the plus sign in bottom right, then click on world trade.

Put up to 10 items in the slots from your inventory.

In the top right is the X out button. Click it as fast as you can and your items will duplicate how ever many times you was able to click.

Use an auto clicker and get more.
