# Trader WorkStation (Interactive Brokers)

**Interactive Brokers** customers can setup connection of the Tiger.com platform to **Trader Workstation terminal**.

{% hint style="warning" %}
When connected to TWS, there are limits on the number of tick data connections that the terminal can be subscribed to at a time. More information is available in the [documentation on the Interactive Brokers website](https://interactivebrokers.github.io/tws-api/market_depth.html#limitations), as well as in the technical support of the broker. 

If the limit on the number of instruments is exceeded, a pop-up window will be shown in the Tiger.com terminal with the corresponding notification: `Max number of tick-by-tick requests has been reached.`

{% hint style="info" %}
When using a connection to Trader WorkStation and viewing the trade feed, you may periodically see differences in the form of additional ticks that may appear in the [terminal windows](https://support.tiger.com/english/windows), but not in the feed of Trader WorkStation. Tiger.com Windows displays only the information that is broadcast by the Trader WorkStation terminal via the API, therefore, there is no error in the Tiger.com Windows terminal itself.
