The System Risk Controls dialog box enables you to configure constraints that limit your risk exposure for orders submitted by the AutoTrade agent. Pairs that breach a system risk constraint automatically have their AutoStatus changed to Suspended. The agent monitors the status of each suspended Pair to see if the constraint has been removed or is no longer breached, and if so, changes the AutoStatus to On for the Pair.
If a Pair’s AutoStatus is changed to Suspended, the reason will be displayed in the Message Log provided that the MsgLog checkbox has been selected in the Summary pane.
