I'm trading the 10y note march contract (symbol TYH09 on tradestation) and I just need a little clarification on when traders rollover to the June contract. I've read elsewhere on elitetrader that it is 1 or 2 days before first notice day, which for the march contract is 2/27 or this Friday. So what day should I start trading the June contract? Wednesday or Thursday? I'm curious as to why the old post I read on elitetrader used "1 or 2 days" Which is it, one or two days? Thanks in advance.
