Help with Trading?

I've looked at multiple guides, and I know how to set up a trade chest... but - do you put the item(s) you're selling inside the chest, and if you're buying, do you put the requested item(s) in, and then take out the item being sold?

Thanks.

When you are selling an item you put the item you are selling in the chest and if you are buying for example you are buying 64 cobble for 1 grass then you put the grass in.

 

Commander, I can always show you.

You are selling 64 cobblestone for 1 grass.

You must:

Have 64 cobblestone in the chest, and that will be replaced with 1 grass once the user has bought the item.
Have an empty space in chest​

 

Right click the sign as will do the trade for you if you have the correct items. You don’t have to open the chest to buy, but you do to stock it again.
