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? EARNINGS READING — NEW Read more than the book — read the financial statements too. One switch on the Home screen takes you to a quiz on reading earnings reports. • Six areas — balance sheet, income statement, cash flow statement, segments, ratios and guidance • Seven questions a set, against the clock — the faster and more accurately you read, the higher your score • Three levels, Lv1 to Lv3 — at Lv3 more than one answer can be right • Choose the standards you are tested on — US GAAP, IFRS and Japanese GAAP • Weak-point mode and a miss note to drill what you get wrong • An explanation for every answer and a built-in glossary — look up a term on the spot • Quick drills for a spare minute Statements are from fictional companies. Earnings reading needs an internet connection; questions and explanations are available in English and Japanese. TRAIN ANYWHERE, SAFELY 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?
