where do you park your cash at IB?

I am new to IB, and would like to park some of my cash that is not currently used. Where do you park your cash?

 

I will soon start to use the TRXT ETF. Hurts buying power though

 

expense ratio of 0.55% little high

 

Agreed. A little high for a bond etf.

 

Gross has beat the market by 100bps or more over the last 2-3 decades
