Switch Mode exists because markets move and strategies evolve inside a single trading session. A trader running a directional long in One-Way Mode can flip to Hedge Mode to overlay a tactical short against the same contract without closing the runner. A trader who has finished hedging can flip back to One-Way Mode to simplify position tracking and net exposure.
Switch Mode also helps traders who want to test Hedge Mode without committing to closing a profitable position first. The position mode no longer dictates when a trader can adjust strategy, which removes a friction point that previously forced close-and-reopen decisions.
