When you first open TWS, a sample Quote Monitor displays
several sample lines of data. Before you
trade an asset, you’ll want to be able to see streaming data for the asset.
A market data line represents an individual ticker, and displays the product
type, order destination, ask and bid prices, and any other defining attributes.
You can add a market data line by typing a symbol directly into the Contract column of
the Quote Monitor.

on the trading screen.
If you choose Smart as the exchange (rather than selecting
Directed and then picking a destination) the market data is aggregated
and the default order routing is Smart. From a display perspective,
ticker lines that use aggregated Smart data do not display Smart in
the data line. TWSwill only show the exchange if you elect to direct
route. When you create an order, regardless of the market data selection
you can modify the order routing destination on a per-order basis
using the Destination field.
In the Contract
Selection box, select a contract(s) and click OK. For assets requiring right, expiry and strike price, use the Selector box. In-the-money contracts are highlighted. Use the Smart dropdown to choose a single exchange.
Note: Notes about
Market Data use
A market data line is considered “active” when
Each alarm that you set always uses one line of market data
whether or not you are viewing the asset that contains the alarm.
Market data requested through an API has top
priority, followed by data requested by alarms, and finally basic
market data display. This means that if you are viewing a trading
page that includes 100 lines of market data, and you also have price-activated
alarms set for 6 other contracts, those 6 contracts will receive market
data, and your trading page will only show data for 94 contracts.
The option chains in the OptionTrader do not
count against available market data lines.
