About The Order Book
The Order Book explains market microstructure — the mechanics of how an order becomes a trade on a crypto venue.
The premise
Almost everything written about crypto trading is about direction: what to buy, when, and why. That writing is abundant, and it is mostly not falsifiable.
Underneath it sits a layer that is entirely mechanical. Orders arrive at a venue, they rest in a book or consume it, they match under defined priority rules, they generate fees according to a published model, and derivatives positions exchange periodic payments according to a formula. None of that depends on anyone’s view. It is the same machinery for everybody, and it explains a large share of the results people find inexplicable.
That layer is what this site covers, and it’s the only layer where a page can be straightforwardly right or wrong.
What you’ll find
The limit order book — bids, asks, depth, and price-time priority. The spread, and what it actually represents. Order types, and the central trade-off that a guarantee of price and a guarantee of execution are mutually exclusive: market, limit, stop, stop-limit, post-only, immediate-or-cancel, fill-or-kill, reduce-only, and what each one actually promises. Slippage, and why it is a different thing from market impact. How a large order walks a book and what that costs. The maker-taker fee model, rebates and tiers, and the full cost of a round trip. Perpetual futures and the funding rate: who pays whom, why, and how a contract with no expiry stays tethered to a spot index. Mark price against index price against last traded price, and why liquidation references one and not the others. Partial fills, queue position and latency, as concepts.
What you won’t find
Advice. Nothing here recommends an action, a setting, an instrument or a venue. The site describes what mechanisms do. What anyone does with that is entirely theirs.
Predictions. No forecasts, no targets, no directional commentary about any asset or about the market, not even as an aside. Microstructure has no direction, and neither does this site.
Named venues, tokens or products. No endorsements and no comparisons. Venue conventions differ in ways that go stale quickly, so posts describe models rather than interfaces, and every signature block carries a row flagging what varies.
Current numbers. No fee rates, tier thresholds or funding intervals presented as fact — they change constantly and differ everywhere. Where arithmetic needs a number, the number is round, synthetic, and labelled illustrative.
Strategy or code. Signals, indicators, position sizing, risk management and backtesting are a different subject, and so is anything involving a library or an API.
Risk-free framing. No mechanism here is described as protection. Every one has a failure mode and it appears in the same passage as the mechanism, because a stop-loss explained without gaps and non-fills is a sales pitch rather than an explanation.
Why microstructure is worth understanding
Not because it produces returns — it doesn’t, and this site makes no claim that it does.
Because it’s the part of trading where surprise is entirely eliminable. A fill worse than the quote, a fee larger than expected, a payment appearing overnight, a stop that triggered and filled somewhere else, an order that never executed because it was set to post-only into a moving market — every one of those is a mechanism behaving exactly as designed, and every one is predictable in advance by someone who knows the design.
Removing that category of surprise is a small, achievable thing. It’s what the site is for.
