Depth of Market

The Depth of Market (DOM) displays bids and asks for a particular instrument at the currently best prices (closest to the market).

The Dept of Market is different on the exchange and over-the-counter markets:

  • If an instrument is traded in the exchange mode, in which related trading operations are sent to an external trading system (an exchange), the DOM features real prices and order volumes from market participants.
  • If an instrument is traded in the over-the-counter (OTC) market, the Depth of Market can be formed based on the quotes of the broker, who may provide different prices depending on the buy or sell volume. If the broker does not provide volumes, the DOM window functions as a scalping tool, which allows placing of market and pending orders with a single click. In this case, the Depth of Market displays price levels calculated based on the Bid and Ask prices using the price change step.

For more information about prices in the Depth of Market, please see the Price Data section.

The depth of market displays information on buy and sell orders

To open the depth of market of a financial instrument, click "Depth of Market Depth of Market" in the context menu of the Market Watch.

  • The number of bids and offers displayed in the DOM is determined by the symbol parameters set by the broker.
  • The availability of the Depth of Market feature for exchange instruments is not guaranteed and depends on your broker.

Operations of two types are performed from the depth of market:

  • Market Operations — buying/selling a financial instrument at the current market price;
  • Trade Requests — placing various trade requests (pending orders) to buy/sell a financial instrument at a specified price (which is currently unavailable on the market).

Market Operations #

A market operation is buying/selling a financial instrument at the best price currently offered in the market.

Execute a market operation from the depth of market. Click on the appropriate trade command in the depth of market of the appropriate symbol specifying the required amount. If "One Click Trading" is enabled, this request is immediately sent to the server without specifying any extra conditions (trading dialog is not displayed).

Suppose we have executed a 20-lot buy operation, while the following offers are currently available in the market:

Market offers in the depth of market

Since we have requested 20 lots with the Fill or Kill condition at the market price, the required volume will be made up of the nearest market bids. If the order contained a certain price, then it would be executed only at this specified price and only in the specified volume.

You can view the history of order execution in the "History" tab of the "Toolbox" window:

The order is filled by several offers closest to the market

You see here that the final volume of 20 lots was received from a few offers closest to the market. The corresponding offers disappear from the depth of market.

Trade Requests #

Placing a trade requests means creating a pending order to buy/sell a financial instrument at a specified price, which is currently not available on the market. Depending on how requests are processed on the server, they can be displayed directly in depth of market (mostly limit requests) or wait for execution on the broker's side (mostly stop or stop limit requests) and then be converted into a market order.

Here is an example of placing a limit request to buy 3 lots of the futures contract RTS-6.13. Specify the required volume in the "vol" field and click on Set Buy Limit (in the Bid price area for the Buy Limit order) or Set Sell Limit (in the Ask price area for the Sell Limit order) in the "Trade" column in the line of the price, at which you wish to place an order. If "One Click Trading" is enabled, this request is immediately sent to the server without specifying any extra conditions (trading dialog is not displayed).

Examine "Quick trading" section to learn how to quickly manage orders in the depth of market.

When placed successfully, the request appears in the depth of market:

The placed request is displayed in DOM

The newly placed order is displayed in the "Trade" column — BLIM 3 (Buy Limit order of 3 lots). As soon as there is a market participant ready to sell the financial instrument at the specified price, the order will be filled and will turn into a position.

Stop and Stop Limit Orders

Usually, Stop and Stop Limit Orders (Buy Stop, Sell Stop, Buy Stop Limit and Sell Stop Limit) are not sent to an external trading system (exchange) directly as opposed to limit orders. Until reaching the stop price, these orders are processed within the MetaTrader 5 platform.

  • Upon reaching the stop price specified in a Buy Stop or Sell Stop order, an appropriate market operation is executed.
  • Upon reaching the stop price specified in a Buy Stop Limit or Sell Stop Limit order, an appropriate limit request is executed, which will be visible to other market participants.

Time & Sales and Tick Chart #

Time and sales and a tick chart of exchange instruments with real transaction prices is displayed in the Depth of Market.

Time & Sales

The Time & Sales feature provides the price and time of every trade executed on the exchange. Information on every trade includes the time when the trade was executed, its direction (buying or selling), as well as the price and volume of the trade. For easy visual analysis, different colors are used to indicate different trade directions: blue is used for Buy trades, pink for Sell trades, green means undefined direction. Trade volumes are additionally displayed in a histogram.

Time & Sales

How Time & Sales can help you understand the market

The Time & Sales feature provides tools for a more detailed market analysis. The trade direction suggests who has initiated the trade: the buyer or the seller. The volume of trades allows traders to understand the behavior of market participants: whether the trades are performed by large or small market players, as well as estimate the activity of the players. The trade execution speed and the volume of trades on various price levels help traders to estimate the importance of the levels.

How to use Time & Sales data

In addition to the visual analysis of the table, you can save the details of trades to a CSV file. Further, they can be analyzed using any other software, such as MS Excel. The file contains comma-separated data:

Time,Bid,Ask,Last,Volume,Type
2016.07.06 16:05:04.305,89360,89370,89370,4,Buy
2016.07.06 16:05:04.422,89360,89370,89370,2,Buy

2016.07.06 16:05:05.968,89360,89370,89360,7,Sell

If you want to save data to a file, open the context menu and select "Export Ticks to CSV".

Filter by Volume

Deals with the volume less than the specified value can be hidden from the Time & Sales table. This filter allows to show only large deals in the Time & Sales window.

Double click on the first line in the Time & Sales window, specify the minimum volume in lots, and then click on any other area of ​​the Market Depth. Trades will be filtered, and the current filter value will appear in the volume column header.

Filtering trades by volume

You can also specify the minimum volume using the Time & Sales context menu.

Tick Chart

All transactions conducted on the Exchange are plotted on this chart:

  • Red circles show Sell transactions.
  • Blue circles show Buy transactions
  • Green circles appear when the direction of the transaction is undefined. It is used when the exchange does not transmit the direction of a transaction. In this case, the direction is determined based on the price of the transaction as compared to prices bid and ask. A Buy transaction is that executed at the ask price or above, a Sell transaction is executed at the bid price or lower. The direction is undefined if the price of the transaction is between the bid and the ask.

A tick chart with Time & Sales

The larger the circle, the greater the volume of the transaction. Transaction volumes are also shown as a histogram below the tick chart.

Using the "Synchronize" command in the context menu, you can control the display of deals charts (circles and histogram):

  • In the synchronous mode, the deals chart is tied to the tick chart and they both have the same time scale.
  • In the independent mode, the deals chart is not tied to the tick chart, and the deals are drawn one by one.

At the top and bottom of the histogram, the total volumes of the current Buy and Sell offers are shown.

The vertical scale of the tick chart is the Market Depth (i.e. its levels). Price change ranges which are not available in market depth are displayed as straight lines on the tick chart. To view the most accurate tick chart, enable the extended mode and the display of spread values for the Market Depth.
