There seems to me to be a limited but long standing chart issue with the 6E contract. It is a bit odd in that it only seems to effect the 6E chart - basically the 6E chart stops updating from time to time. I say that simply cause I've not seen it happen with any other market but then I don't follow many...... The work/round seems to be to change the chart periodicity to anything (say 5min) then change back to your preferred timeframe and it starts updating again. This fixes it until it freezes again. It happens a few times a day. This problem has been discussed before on ET under various OEC problem threads. Other than that my OEC platform is/has been fine over the last few weeks (since the last major s/w release).
