This morning when I opened TWS the last price on ES and YM were stuck on 1129.5 and 10475 respectively and they have remained there all day. NQ last price is ok. Bid and ask on all are ok. I use Sierra charts and Buttontrader and both have worked fine up till today. Sierra charts are not updating as they apparently update off of last price. I closed Sierra and Buttontrader, uninstalled TWS and reinstalled it. No help. I opened TWS on my other computer and it was the same. I went to my mother's computer and pulled up the TWS browser platform and the last price was still stuck. This tells me that something is wrong at IB's end but they say they cannot find anything wrong. Any ideas?
