Overview

Market Depth in Short.

A price on a screen is a summary. Market Depth is the detail behind it, and having it inside a trading mobile app for operations in the Forex and exchange markets changes how orders get placed. Instead of a single best bid and offer, you see the orders resting at each level around the current price, and with them a sense of how much size the market can absorb before the price has to move.

For a trader working small size, that information mostly explains things after the event: why a fill came through a fraction away from the expected price, or why a level held for twenty minutes and then gave way in seconds. For anyone working larger orders it becomes part of the decision itself. Join the queue at a level, sit behind it, or cross the spread and take what is there — three different choices that look identical on a plain chart and completely different in the book.

Market Depth pairs naturally with the netting system used on exchange markets, and Trade Master 9 supports the advanced version of it. Because the platform accounts for orders and trades separately, an order placed from the depth window stays legible afterwards: you can see the instruction, then the trade that resulted from it, rather than one merged entry.

What you see depends on what your broker's feed supplies, since depth data comes from the venue rather than from the terminal. Where it is available, it sits alongside the four execution modes and the full order set described elsewhere in this section. For the wider picture of the app — the charts, alerts, copy trading and automation built around all of this — see the TM9 home page.

Reading The Book.

The advanced Market Depth in Trade Master 9 shows resting orders and supports exchange-style trading.

What Market Depth shows

Market Depth displays the orders resting around the current price, so you can see the liquidity available on each side rather than a single best bid and ask.

Trading from the book

Because the platform accounts for orders and trades separately, orders placed from the depth window stay readable in your order list and history.

Where it applies

Market Depth is most associated with exchange markets and the netting system, both of which the platform supports directly.

At the book

What Depth Tells You.

Three notes on what resting orders do and do not reveal.

In practice

Traders who scalp or work large orders use the book to decide not just direction but placement — whether to join a level, sit behind it, or cross the spread. The same information also explains slippage after the fact.

Worth knowing

Depth data comes from the venue through your broker, so the amount of the book you see depends on their feed. The platform displays what is supplied rather than generating it.

Who it is for

This page is for exchange traders and anyone working larger orders, where placement inside the spread matters as much as the entry itself.

Context

Where Depth Applies.

Which markets publish a book, and which do not.

Depth is an exchange feature

Market Depth shows the orders currently resting at each price, which is a picture only a centralised venue can publish. That makes it an exchange-market tool first: the Forex market has no single book, so what you see there depends on what your broker aggregates rather than on the whole market.

Good to know

TM9 is a software development company and does not provide investment or brokerage services. The platform supplies the trading terminals, analysis tools and automation; your broker holds the funds, sets spreads and leverage, and executes the orders the platform sends. Trading carries a real risk of loss, and signals or robots are tools rather than financial advice.
