March is officially top-step on Wednesday of this week, but you can easily roll your position before that, if you are long, can probably even wait a little for the spread to come off and get in cheaper into March. Interesting note on Friday there were a ton of spreads trading in the pit between Goldman and Barclays, which is essentially Pimco and Citadel rolling their ten year positions, so at this point seems highly doubtful any squeezes may occur.
