Maple Trading System
| This article contains information no longer in-game, and are thus historical records of MapleStory. |

The Maple Trading System (also known as the MTS) was a feature that allowed players to buy and sell items for NX Cash (GMS, JMS), Cash Points (CMS), Gash (TMS) or A-Cash (MSEA), accessible via a button next to the Cash Shop. There were several tabs that players could navigate through:
- For Sale: a list of items currently being sold
- Wanted: a personal wishlist for players that are interested in buying specific items
- Auction: players could place items up for auction, with a set duration between 24 hours and 168 hours (1 day - 7 days)
- My Page: players could view their Cart, Offers, Transaction History, and Auction details
Players listing items for sale would enter a Listing Price (before taxes), and will be shown a Total Price (after taxes), with the tax costing additional NX Cash / A-Cash. A buyer would have to pay the Total Price, while the seller would only receive the amount they entered on the Listing Price. Any unsold items would be placed in the Transfer Inventory, which was also used as an alternative Storage by many players.
The Maple Trading System was available in JapanMS, GlobalMS, ChinaMS, TaiwanMS and MapleSEA. It was removed by GlobalMS, TaiwanMS and MapleSEA due to exploitation, while JapanMS removed it in favor of the Meso Market, and ChinaMS removed it in favor of the Auction House.
