I think leaving the trade is not the solution. After experiencing a loss in trading, as a trader should make it an experience. Losses are always a major problem in trading, so as a trader you have to practice your skills and implement better strategies.
Leaving trading to get more skills in trading is a better option better than quiting trading entirely. Trading can always be tempting and discouraging when loses always occur. You a trader that had incurred multiple loses can look at his mistakes and get a better skill about trading, coming to trade again will have little loses if he had acquired better skill that can initiate good profits to them.
