All clients initially receive 100 concurrent lines of real-time market data and always have a minimum of 100 lines of data. This applies to any account type and it is the initial configuration for any new account. Market data lines can be increased based on monthly commission amounts, Equity Level, and Quote Booster subscriptions.
After the first month of trading, the quantity of market data is allocated using the greater value of:
- USD monthly commissions divided by 8
- USD equity multiplied by 100 divided by $1,000,000
(rounded down to the nearest integer)
- 100
To view the current number of market data lines that you are requesting, press CTRL + ALT + = or CTRL + ALT + C for non-English keyboards or Command + Option + + for Mac users simultaneously on your keyboard. A message will populate with the total number of market data lines allowed and currently subscribed.
Clients can increase their allowance of simultaneous quotes windows by purchasing monthly Quote Booster packs. Please note, in order to receive real-time market data customers must subscribe to market data.
