Schwab. But I'll go through TreasuryDirect since I've never bought T-Bills before.Who is your broker? You can do this through most major brokerages as well with certain account authorization. I actually like the setup on TreasuryDirect better than schwab, but either is fine. You can do this in $1000 increments so don't need institutional sized accounts.
Purchasing some 13 weeks bills being auctioned tomorrow. Going to try to synchronize these purchases with upcoming rate hikes.
Markets looking sloppy right now. This is going to be in oversold territory soon so will be looking to use some speculative cash on calls in the next few days.
