Introduction / Features
This plugin is part of a Suikoden features plugins series and works similarly to the Trade Shops (although there's still room for some improvements).
For those not familiar with it, it's an alternative kind of shops (doesn't replace the standard shops) that works like financial markets.

So what does this plugins do exactly ?
It allows you to create special shops that buy and sell only specific items.
Every shop have limited items stocks, and the value of those items changes according to those stocks.
Every shop can also refill ("produce") at least one item on its own, while the other items will eventually "vanish" from the stocks.

How to use
While I tried to make it easy, this plugin is pretty advanced and I strongly advise to have a look at the demo to understand better how to use it properly.
Be sure to carefully choose what variable you want the plugin to use and never overwrite that variable in your events.
You will need to use the plugin commands to create your shops and define their stocks of items. After this step your shops will be useable, but to activate the auto-update property of the shops (stocks and prices variations), you will need to use the "updateTShops" command in a parallel common event (don't forget to turn ON the switch of this event).

Demo
There's a demo project available to download on my itch.io page showing a possible use of this plugin.
