Can I hold buy and sell on the same symbol? Hedging vs netting

Your account runs in one of two position modes. In hedging mode (the default) you can hold multiple positions on the same symbol at once, including opposite buy and sell positions — they don't cancel, they coexist, and only the larger side's margin is charged while the covered volume is effectively free. In netting mode you hold a single net position per symbol: a new opposite order reduces, closes or reverses the existing one instead of opening a second. Most accounts are in hedging mode. If you're unsure which mode you're on or want it changed, contact support; the mode affects how used margin is calculated and whether a second order adds a position or nets against the first.
