Market Depth.

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.
