IB TWS vs IB Gateway?

[Murphy67]

What is the key differences TWS vs Gateway? Should i disconnect TWS everyday?

Hello Murphy67,

It is recommended to restart NinjaTrader on a daily basis (which would disconnect you from TWS in NinjaTrader).

Please see the information below from the Interactive Brokers connection guide.

IB Trader’s Workstation (TWS) – Fully featured Trading Application provided by Interactive Brokers (allows you to view and manage API orders which were submitted through NinjaTrader)

IB Gateway – Lightweight Interactive Brokers interface (provides status updates on the API connection but does not provide interface to manage API orders)

If you like more information on these interfaces, I suggest to contact Interactive Brokers.

i will automated trade to IB. If i restart NT everyday what will happen to my open position in NT and IB. strategy will start from the begining every day or open position will continue as it is

Restarting NinjaTrader does not close any open positions.

It depends on the Start Behavior settings you have selected. Please see the link below for more information.
