Have you try using split screen, half Schwab.com the other half StreetSmart Edge?They only show same day's P/L and not prior days. You then have to go to Schwab.com to see your total P/L. I am thinking of moving my account. Looking at my prior P/L is the only way to trade for me.
I also tried Fidelity's Pro platform and it was really bad.
Any suggestions?
