I see this situation like you don't have any trading strategy and you don't use money and risk management in your trading. Losing 4% a day is really big, so you need to secure your deals really in order not to allow such situations to happen in the future. I fell that you don't have any decent and precise trading strategy. It looks like that you trade on your perceptions and feelings rather than calculations and common sense. Try to trade with bigger timeframes in order to have more time on the market analysis.
