Sometime it shop up but mostly I have to refresh page several times before it show up correctly. I tray several browser and computers and I have the similar problem..
Do you mean the upper graphs on the market data page? So far as I know, nobody else has reported this, but if other's are having trouble we'd like to know.
@CybeRoky: Do you mean the right table with the last trades on market data?
However it's about a 30% chance to see "No trades currently available" there. Then I have to refresh, till I see the trades. In about ~5% cases I also can't see the Orderbook.
