Correct. Opening 1 _Trade_ with a stop loss requires 2 _Orders_.

For a stop loss trade in the IB API, you first open a market order in the desired direction. Then you open a stop order in the opposite direction. IB also requires some "bracket" mechanism for preventing that the second order is opened when the first was not. The result is an open stop loss trade in NFA compliant way. Even though you used to click a single button for this in Multicharts or Sierracharts.
