The 4-hour chart is mainly short-term, with a stop loss of about 40 points and a take profit of 60 -80 points.

In the medium and long term, the stop price is the high or low point of the last wave. Take profit is not set. When the trend reversal is confirmed, manually stop profit and close the position.

Why stop loss? Stop loss is to protect your own list, how much loss your list can bear, and resist the sudden situation of exchange rate fluctuations. For example, some transactions on the exchange have oolong fingers and wrong orders, which leads to rapid market fluctuations. For example, the Swiss franc incident in the previous two years led to the bankruptcy of many traders. Not to mention individual traders.
