The order book as a battle of bulls and bears

This is not a game — it is a live exchange indicator. A crypto exchange order book in real time: every price is a squad, the order size is its strength, and the front line is the current price.

**Spear phalanx**A strong support / resistance level.

How to read the battle

Bears at the top are sell orders (asks). Bulls at the bottom are buy orders (bids).
The glowing line between the armies is the current price — the front line.
A squad is a price level, a warrior is a lot of volume. Thicker levels bring heavier troops: soldiers, shield-bearers and champions.
A spear phalanx marks a large order wall — strong support or resistance.
Arrows and shurikens are market trades hitting the book.
A fallen warrior is a filled order. A ghost is a cancelled order — the way to spot walls that vanish before price reaches them.
When price breaks a level, a horn sounds and a volley of shurikens flies.

Why visualize the order book?

A classic order book is two columns of numbers that change many times per second. It is hard to see which side is stronger, where the large walls stand and which orders disappear before price gets there.

Order Book War shows the same public market data as two armies. The size of an army is liquidity, and every trade and cancellation becomes an event you can see. New to order books? Read the guide: How to read a crypto order book.

FAQ

Is Order Book War a game?

No. It is a live market indicator that shows the real Binance order book in a game-like style. Only the “Who pushes further?” mode is a small guessing game, and it involves no money.

Where does the data come from?

From the public Binance API in real time: order book depth, trades and 24h statistics. Other exchanges are planned.

Can I trade in the app?

No. The app does not connect to exchange accounts, does not need API keys and does not place orders. It only visualizes public market data.

Is it free?

Yes. No ads, no in-app purchases and no registration.

Which devices are supported?

Android through Google Play, and any modern browser on a computer or phone. iOS is planned.

What is an order wall?

A large limit order, or a cluster of orders, at one price. In Order Book War it appears as a spear phalanx. Walls often act as support or resistance, but they can be cancelled — then a ghost appears.
