Two instances of TWS

[guillembm]

There is any help guide on the setting for IB TWS and NT to open 2 different TWS instances on the same computer? One for testing and the other for real trading

thanks

Hi guillembm,

There is not official documentation for this but it should be possible, by providing a unique port # and starting instances of TWS manually. Of course IB would have to permit your account to be logged in twice concurrently.


1) Manually start TWS from the desktop, if you have two accounts start it up twice with each account logged in.

2) When platform has started, Click Configure > API Settings > Socket Port > Provide a unique value. Default is 7496, leave this as is for the first username. Add 1 to this value to be 7497 on the second account (or instance) so each account has a unique port value.

3) In your NinjaTrader connection for this account (Tools > Account Connections), match the port with what you specify in TWS for each account connection.

4) Connect in NT using File > Connect, you will do this twice for both account connections.
