Is there a platform out there that does not have massive lag in a demo account? I'm currently trying out Think or Swim but the demo is lagged so far behind current prices its not funny. I have also heard it is slightly laggy with a live account too but I don't got any solid confirmation on that. The orders are incredibly annoying in the ToS demo account because it tries to place your order at the price the stock was at 10 - 15 minutes ago while displaying the current price under the "monitor" tab. Any recommendations?
