All customers initially receive 100 concurrent lines of real-time market data (which can be displayed in TWS or via the API) and always have a minimum of 100 lines of data. After the first month of trading, the quantity of market data is allocated using the greater value of:
The number of symbols that can be viewed simultaneously via the TWS deep book windows (including BookTrader, Market Depth and ISW) is determined as follows: one unique symbol for every 100 allowed lines of market data, with a minimum of three and a maximum of 60. For example, a customer with the default allowance of 100 tickers will be able to simultaneously view three deep book windows. A customer who, based on commissions, equity or other criteria, is allowed 500 tickers will be able to simultaneously view five deep book windows. Note that this number may change month to month if the number of allowed tickers for your account changes.
- USD monthly commissions divided by 8
- USD equity multiplied by 100 divided by $1,000,000
(rounded down to the nearest integer)- 100
- Example 1:
In month two, your account shows the following values: USD Monthly Commissions: $16, USD Equity: $950,000
Using the calculations above, you would still receive the minimum 100 lines of data, since: $16/8 = 2
$950,000 x 100 / $1,000,000 = 95- Example 2:
In month three, your account shows the following values: USD Monthly Commissions: $500, USD Equity: $1,245,000
Using the calculations above, you would receive 124 lines of data, since: $500/8 = 62.5
$1,245,000 x 100 / $1,000,000 = 124.5, rounded down to 124.
