just make your trading plan and follow it, if you entered into the trade, then just follow your plan. If you put a target for the profit, just close it at that level or take a risk and take your initial investment back.
According to the stop loss, if you set up a stop loss, when it is close to that level, just be brave to analyze the situation, if the trend does not look good, just close it and try to return the loss in the next trade, better than just holding a loss in your portfolio for long term.
