1, stop loss by the amount of funds: that is, before entering the market for crude oil trading, clearly plan how many points to lose as a stop loss. This is a good fund management method, but the premise is that traders should design their own profit-taking points and stop-loss points in combination with their own winning rates. For example, if you operate ten times, gain five times, stop loss five times, take profit 120 points, stop loss 50 points, then the result must be winning. How to get this profit model, first of all, we should use the risk-return ratio (generally 1: 3) to find the model, second, we should deeply understand the fluctuation nature of market operation, and third, we should comprehensively judge the trend direction, trend type, trend development period and other crude oil market trends.

2. Stop loss with time: This method is mainly used for intraday ultra-short crude oil trading mode. Intra-day ultra-short mode refers to the trading mode in which traders hold positions for as few as a few seconds and as many as a few minutes in order to obtain the price difference of several or dozens points in a certain period or part. For this model, the trading principle is to make use of the influence of the external market, the breakthrough of the support level and pressure level in the market, the false breakthrough and the sudden news to make a profit. Its advantage is that when the judgment is correct, it can gain profits instantly, even excess profits; When you make a mistake, you can get away with it. It requires traders to have good reaction ability, be able to quickly evaluate the general atmosphere and potential direction of the market, and always pay attention to the market, especially when holding positions.

3. Stop loss according to the breakthrough support level or resistance level: in the spot crude oil trading market, stop loss and take profit at support level or pressure level, that is, buy and open positions at support level, sell and transfer at pressure level, and stop loss below support level after buying, and vice versa. This is the most commonly used stop-loss and profit-taking method in commodity trading, which is suitable for all trading strategies such as intraday, short-term, band and medium-long term. The premise of using this method is to judge the support and pressure comprehensively and accurately.

The advantage of this method is that the stop loss setting can follow the fluctuation of crude oil market as much as possible, but the disadvantage is that there are many users, so there are often false breakthroughs. Therefore, when applying this method, we should be able to identify the trap and re-enter the market according to the new signal after exiting the crude oil trading market.

After all, spot crude oil investment is risky. Therefore, it is suggested that novices can try to invest with simulated accounts before formal investment operations, and then conduct actual operations after they have a deep understanding of the crude oil market, thus creating better conditions for profit.
