Trading Again

Ok. So I go off to a client meeting having done one trade at a profit (200 shares of Morgan Stanley) and feeling very good that I was not at risk, and leaving one "go with" unexecuted trade on 200 shares of Morgan Stanley set above the last high of the day before, that never went off. But when I returned after 5 pm my account showed me with a loss and another 200 shares of Morgan Stanley. The Schwab trading platform "streetsmart.com" is defective. (I found this out by googling "defective Schab Trading Platform." There was a January 29th notice put out by Schwab itself. So trading under that platform doesn't work. Like the rest of Wall Street. Appearance is not reality.
