The order book, and the games played in it

The futures track read the central book's honest microstructure. Crypto's books are the same machinery with less policing - so the reading skill adds a scepticism about displayed orders the regulated venues did not require.

What the book shows, honestly and not

• Filled trades are real: the tape of executed trades happened - the honest core, as everywhere; volume-at-price and where large size actually crossed are trustworthy on reputable venues.
• Displayed depth is an intention, weakly enforced: orders can be posted and pulled - spoofing - to paint a book that does not reflect willingness to trade; lighter surveillance than regulated markets means the behaviour persists more openly.
• Thin books amplify the games: on shallow pairs a single participant's posted-and-pulled orders move the visible book noticeably, and the tape shows the signature to a reader who knows to look.

Reading through the games

The discipline is the futures track's, hardened: trust fills over displays, weight the tape of executed trades above the resting book, and treat a wall of displayed depth as a claim to be tested rather than a fact to lean on - especially on thinner pairs and lesser venues. None of this makes the retail reader a microstructure trader, as the futures track said; it makes the book legible, with the added crypto caveat that the intentions layer is dressed up more freely here than anywhere else the platform teaches.

The venue-quality dimension

Book integrity tracks venue integrity: the reputable, higher-surveillance exchanges restrain the games toward the futures-market norm; the fringe venues are where the tape is least trustworthy and the books most theatrical - lesson 4's volume-honesty problem, in the order book. The composite habit from this module compounds: reputable venue, real base, genuine volume, and now filled-over-displayed reading - the crypto reader's standing filters, applied before any level or pattern is believed.
