my experience using "Return all to primary currency" is selling my coin at my last sell order, not at currently running price, so it takes 5-6 hour to complete all market

at first I thought it is going to cancel all my buy and sell order, then after all order canceled and return to available balance, it going to sell all available balance at currently running price, which in my experience the coin sold faster

I know selling at currently running price can be loss in gain, but I want my all btc back after 24 hours trading
