Viewing Coinbase market data

You can view market data for Coinbase instruments in the MD Trader, Market Grid, Time and Sales, and Charts widgets.

Note: Position fields or columns in these widgets are not shown for TT Crypto users.

Coinbase market data in MD Trader

When viewing Coinbase market data in MD Trader, consider the following:

  • Fractional working order quantities up to eight decimal places are supported in the Bids and Asks columns. LTQ is also displayed as a fractional quantity up to eight decimal places.
  • Empty price levels can be hidden to show only available prices at each price level.
  • Quantities default to three decimal places of precision, but can set to show 0-8 decimal places.
  • Market data is displayed for a continuous 24 hour cycle (not daily or per trading session) as follows:
    • Net change — Calculated as a continuous 24-hour net change based on the Open price from 24 hours ago.
    • O (Open) — Shows the opening price of the instrument 24 hours ago.
    • H (High) — Shows the highest price for the instrument in the last 24 hours.
    • L (Low) — Shows the lowest price for the instrument in the last 24 hours.
    • V (Volume) — Shows the total volume traded in the instrument over the last 24 hours.

The following example shows Coinbase market data displayed in MD Trader.

Floating price ladder

Empty price levels can be hidden to show only available prices by enabling Settings | Only show available prices in the MD Trader widget.

Note: This setting removes the static aspect of the ladder, which may result in orders being submitted at a price level different than the one you clicked on if the prices moved while clicking the mouse.

When "Only show available prices" is enabled, MD Trader briefly shows a blank cell where a price level is removed before it compresses and adjusts the price ladder. This allows you to to enter an order at the correct price before all the prices move, and helps to clearly show quick rallies or sell-offs in the market.

Tip: You can "freeze" the price ladder at any time by holding down the Shift key.

Price consolidation

You can consolidate prices at specific price increments by enabling the Settings | Price increment per row option in MD Trader. When enabled, aggregate order quantities between each price increment are displayed at each price level. For example, a price increment of "50" entered for BTC-USD results in prices ticking in .50 increments.

Quantity display

Quantities can be displayed with 0-8 decimals of precision using the Quantity display decimal places option in the Preferences | General tab. By default, this option is set to "3".

A "+" is shown after the last displayed decimal to indicate additional quantity (e.g., ).

If the actual quantity equals your display setting value, or if the remaining decimals are "0", then the decimals are displayed without the "+" (e.g., .

The following fields will adhere to the "Quantity display decimal places" setting:

  • The WrkBuys and WrkSells columns in the Market Grid
  • MD Trader working order cells and LTQ
  • Net positions in MD Trader and Market Grid

    Note: Net position fields are not shown for TT Crypto users.

  • The Qty column in Time and Sales
  • Working order cells, LTQ, and net positions in Autospreader legs with instruments that support fractional quantities.

Note: The Order Book, Audit Trail, and Fills widgets will show the full quantity regardless of this setting.

If you click a formatted quantity when "Quantity display decimal places" is enabled, the actual, full quantity will seed in the appropriate widget field. For example, if you click "1.005+"" in the Net Open Position field in the MD Trader order entry panel, then "1.00511" will be seeded in the order quantity field.

Coinbase market data in Market Grid

When viewing Coinbase market data in the Market Grid, consider the following:

  • The WkBuys and WrkSells columns display the fractional working quantity (in parentheses) and filled quantity to eight decimal places.
  • The NetChg, % Chg, and Vol columns show 24 hour net change, percent change, and volume for the instrument.
  • The Settle column shows the price in the final minute before the session rolls at 6:00 PM CST (7:00 PM DST).
  • Detailed depth only shows price levels with working order quantities by default.
  • Optionally, prices can be displayed with 0-8 decimal places. Any quantity above the displayed amount is indicated with a "+".
  • Position fields are not shown for TT Crypto users.

The following example shows Coinbase market data displayed in the Market Grid:
