Mercator — a trading and manufacturing terminal for EVE

A tool for players who earn ISK on the market rather than in combat: spreads, inter-hub arbitrage and manufacturing. We take EVE’s raw market data and turn it into clear decisions — what to buy, where, when, and what it costs to build.

The in-game market shows prices, not decisions

Thousands of items, each with a spread, volume, volatility and history. You can’t eyeball that, and “buy cheap” without risk context often means getting stuck in illiquid stock.

Raw data is free; the ready numbers live in the picks and the calculator

Net margin after fees, fair value, persistence, turnover in ISK/day. For trading — “Market”, “What to buy”, “Walls” and “Arbitrage” (with a frontier lane to Orvolle); for the factory — “Industry”: build cost down to raw materials, a build-or-buy tree and a batch plan.

How it works

Connect EVE

Log in via the official EVE SSO. We read market data and, optionally, your orders, wallet and skills — read-only.

Trade or build

For trading — liquid items with margin, turnover and risk, plus curated picks. For the factory — a build-cost calculator: ME-adjusted materials, install fee from the system index, what’s cheaper to buy and what to build.

Act on the data

Open an item card, an arbitrage route or a build tree, see market depth and the numbers, decide and trade or build in-game.

Data

  • Source — ESI — EVE Online’s official API by Fenris Creations
  • 5 trade hubs — Jita, Amarr, Dodixie, Rens, Hek
  • Up to 90 days history — price, volume, spread by day
  • Time — EVE/UTC — same as in-game

Honest about the basics

  • We don’t give financial advice — only data and metrics.
  • Profit isn’t guaranteed: EVE’s market is moved by players and patches.
  • Margin without login is computed on bare fees with no trade skills — a lower bound. Log in via EVE SSO and we recompute it from your real skills and standings.
  • Events are compiled from sources (zKillboard, Dotlan, media) and can contain errors.
  • This is a fan project, not affiliated with Fenris Creations Games.
