The order book, readable at a glance
Depth is only useful if a trader can interpret it quickly. TradeX aggregates the book at a price step the trader chooses, shows cumulative volume as a bar, and highlights their own resting orders in place.

Reading the ladder
Everything in the panel answers one question
What will happen if I send this order now.
Adjustable price steps
The book can be aggregated into wider price buckets, which turns a noisy tick-level ladder into a readable picture of where size actually sits.
Cumulative volume
Each level shows both the size at that price and the running total up to it, so a trader can see how far an order would walk.
Your orders in place
The trader's own resting orders are marked at their price level with the remaining quantity, never confused with third-party liquidity.
Click to trade
Clicking a level pre-fills the ticket at that price, which removes the transcription errors that come from typing a price by hand.
Streaming updates
Depth arrives over a streaming connection rather than a polling interval, so the ladder reflects the book rather than a snapshot of it.

The same order book, at full market depth
A spot order book shows the same bid and ask ladder this page describes, at the aggregation level a trader chooses.
What visible depth changes
Better order sizing
Cumulative volume tells a trader where their order stops being absorbed and starts moving the price.
Fewer mistyped prices
Clicking a level is more reliable than typing it, particularly on instruments with many decimals.
Credibility with professionals
Experienced traders judge a platform by its book. A readable one is a retention argument.
FAQ
Market depth: common questions
5 short answers to what teams ask before a demo.
The visible depth is configurable per instrument and per client group. Most desks show a substantial ladder to professional tiers and a shallower one to retail, where more depth tends to confuse rather than help.
No. Aggregation is applied in the panel for display only. The engine continues to maintain the book at full precision, and changing the price step does not affect how orders match.
Yes. Their resting orders are highlighted at the relevant price level with the remaining quantity, distinguished from the rest of the size sitting at that price.
Yes, over a streaming connection. The ladder reflects the current state of the book rather than a snapshot taken at a polling interval.
No. A click pre-fills the order ticket at that price and leaves submission to the trader, so a stray click cannot open a position by itself.
