I set 2 limit oblique orders on a chart. After a while they disappeared from the chart and i thought they where gone. The orders didnt even show in the pending orders list. Then the market move later in the day and I was surprised to see the limit order open a buy position and the market fell. When I then closed the platform it shows that a limit order was still active although not showing in the pending orders. Is this a common bug with the system? How does one set the stop order on an oblique order as again I had the stop loss set at 50 points but this wasnt activate by the hidden order.
