When you trade with HighLow we do not aggregate or net the positions you take. Each position remains isolated. This allows you to employ multiple trading strategies at the same time. When you have an open position and you want to close it, you need to actively close this specific position either through a Stop Loss, Take Profit or by executing at close fully or partially by clicking the Close tab for that particular order on the Trade Ledger. If you take an opposite position in the market on HighLow, you will have hedged your position but not actually closed it.
