Does anyone know what the deal is with this error? (See attachment.) "Not allowed to open new positions at the moment because account valuation may be incorrect." This is a demo account (of course) and as anyone can clearly see, my open positions certainly aren't pushing the limits of the 50:1 margin. Yet, TWS is refusing to place orders. And even worse, sometimes it won't even let you exit a position reporting the same error. Why? Is this what can be expected with a live account? Or is this a demo fluke? Thanks!
