Order Book Trainer: Level 2

About this app

Can you read the order book like a pro? Order Book Trainer: Level 2 is a training simulator that teaches the classic day-trading skill of reading the DOM (depth of market) and the time & sales tape — the same Level 2 information short-term traders watch every day. Watch bids stack up, feel the sell walls crumble, then make your call: is the next move UP or DOWN? Get scored on every read, build streaks, and watch your accuracy climb session after session. HOW IT WORKS • Watch the ladder — live bid/ask depth updating in real time • Read the tape — every print, size and aggressor side as it happens • Make the call — predict the next move before the timer runs out • Get graded — points, streak bonuses, accuracy and an S-to-D grade per session TWO MARKET STYLES • Tokyo style — banded tick tables, special quotes and daily price limits, just like the Japanese equity board • Global style — penny ticks and continuous trading in a classic DOM layout THREE DIFFICULTIES • Beginner — slower tape, shallow book, and live hints that teach you what the pressure means • Intermediate — real-time speed, full depth, no help • Pro — fast tape, strict scoring, and spoof walls designed to fake you out. Can you spot the fake orders? TRAIN ANYWHERE, SAFELY Every price, order and trade is synthetically generated on your device. There is no real market data, no account, no deposits — nothing to lose but your bad habits. This is a training tool, not investment advice. MADE FOR FOCUS • 11 themes — light, dark and pink/blue/yellow/green variants • 70+ languages • Session history with grades so you can track your progress GO AD-FREE (OPTIONAL) Want a distraction-free tape? The optional subscription removes every ad in the app. Subscriptions auto-renew unless cancelled; manage them anytime in your store account. The book is moving. Can you keep up?

• Rounds now move on by themselves after five seconds — tap "Next round" to go sooner, or pause to hold the countdown. • Lost an answer streak? You can now bring it back once per session.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
