EVE Online Market Window Guide: Reading Spread, Depth, Volume & Trend

The first thing you face when you start trading is the market window. In that wall of numbers you only need to read four things — the spread (margin), order-book depth, volume, and the price trend. Those four decide whether an item is worth trading.

This guide covers how to read EVE's market window — the order book and the price-history graph — at a beginner's level, and how to judge an item from those numbers.

What does the market window show?

The market window has two main parts:

• The order list (order book) — the sell orders (Sellers) and buy orders (Buyers) currently posted, sorted by price.
• The price-history graph — daily price and volume over time.

By default it shows the whole region, so to focus on one hub you check the station/system in the order list. Remember that only orders within a single station matter for station trading.

Reading the order book — sell and buy lists

Each row in the order list is one order. The columns that matter:

Column	Meaning	Why it matters
Price	Per-unit price	The basis for the spread
Qty	Units remaining	Order-book depth
Location	Station/system	Check it's the same station
Range	A buy order's reach	Station trading needs "Station"
Min Volume	The minimum a buy order accepts per fill	Your small lot may not sell
Expires	Time left on the order	Spot stale "ghost" orders

Sell orders sort cheapest at the top; buy orders highest at the top. The top two rows — lowest sell and highest buy — set the market's "current price."

Beginner trap: it's easy to miss a buy order's Min Volume. A buy order with a min volume of 100 won't take your single unit. If something you expected to sell isn't selling, suspect this.

Spread and depth — the real margin lives here

Two numbers are the heart of trading.

Spread = lowest sell − highest buy. That's the space for your station-trading margin. The spread has to clear your fees (~5.4% at max skills) to profit.

Depth = the quantity stacked at each price level. This is the trap. Even if the lowest sell is 1.0M, if there are only 5 units there and the next is 1.1M, buying 50 units means your average cost isn't 1.0M. The top order almost always distorts your real buy/sell price — you have to read the book down as far as the volume you'll actually consume to see the true margin.

So don't just read the top two rows — read how many units sit at what prices below them.

Reading the price-history graph

Open the "Price History" tab and you get the item's price over time.

• Horizontal axis = time. From 5 days to 1 year, adjusted with the sliding focus box below.
• Left axis = price (ISK). The lines, dots, and vertical bars above show daily price movement (a moving-average trend, plus each day's median and high–low range).
• Right axis / bottom bars = volume (units). The green bars are daily volume traded.

What to read here:

1. Trend — is the price stable, rising, or collapsing? Place a buy order into a crash and you're underwater the moment it fills.
2. Volatility — a wide daily high–low range means a jumpy price. More risk, but more opportunity.
3. Volume trend — is recent volume holding, or drying up? An item whose volume has died won't fill your orders.

Judge liquidity by volume

The daily volume in the price history tells you how many units actually trade per day. That's the measure of turnover, which matters as much as margin in station trading.

• High volume = deep liquidity. Your orders fill fast and capital keeps turning. Thin margins still pay through turnover.
• Low volume = shallow liquidity. The margin may look wide, but orders sit for days and lock your capital.

If your quantity is huge relative to daily volume, the price may move before you clear it, or your capital stays frozen for a long time.

Reading competition — how many orders are stacked

A tightly packed stack of orders on your side signals fierce competition. An item with dozens of sell orders bunched together has an intense 0.01 ISK war — you'll reprice often to hold the front, and relist fees add up. An item with sparse orders has less competition, but often less volume too.

Is this item worth trading? A 3-second read

Open the market window and scan in this order:

1. Does the spread comfortably clear fees (~5.4%)? If not, skip.
2. Is daily volume enough to absorb your quantity? Check turnover.
3. Is there depth in the book? If the top is big but the book below is empty, the margin is an illusion.
4. Are competing orders too tightly packed? Gauge the 0.01 war.
5. Is the price trend crashing? Check the history graph.

Recap — market window checklist

• Order book: lowest sell / highest buy = current price. Check Min Volume and Range.
• Read spread (margin) and depth (realizability) together. Don't trust the top order alone.
• Use price history to read trend, volatility, and volume trend to dodge crashes.
• Volume = turnover. As important as margin.
• Before trading, do the 5-step read (spread, volume, depth, competition, trend).

The in-game market window only shows the basics. ISK Scout's market analysis layers technical indicators — moving averages, Bollinger Bands, RSI — on top and computes buy/sell timing signals, automating the order-book reading you'd otherwise do by eye.
