The trader must respect his trading plan despite the losses. A good trading plan has a statistical backing and therefore should not be frightened against bad results. No strategy is free from losses but the most important thing is to achieve a final positive balance. A solid growth of capital is more important than great eventual profits. after loss in trade that will difficult for us to manage our emotion, so friend i think after some loss better we take a rest for a while and manage our emotion so we can start new trading without any revenge, but if you have no emotion in your trade you can directly trade and continnou your trading, but for me i rather to wait and take a rest before do more trade to avoid emotional trade and to avoid make more bigger loss
