I have this code here mostly from the example in the steam trade offer manager. It accepts all trade offers fine (without any exceptions). I added some code where the bot would skip the trade offer if the bot didn't receive any items (a gift offer). I'm struggling to create the part of code where I can filter items and create the prices for them for buy orders and sell orders. Could anyone tell me the syntax for that?
