First, control risks. Although the risk of foreign exchange investment is relatively small, there are still some risks in investment. If investors do not control their investment risks well, they may still suffer heavy losses. How to control investment risk? The way is to learn to stop loss. Stop loss is to set an affordable loss point after each opening, so that when the foreign exchange market fluctuates beyond your own judgment, you will automatically close your position and reduce your own financial losses. Second, short-term trading. The advantage of short-term trading is that you can see the investment results quickly, you can get the investment income quickly if you invest successfully, and you can take out the funds immediately if you have something temporary. Third, make small orders. It is the best policy for investors to invest in foreign exchange transactions, because making small orders is less risky. Although the investment income earned is limited, it can ensure that the income is relatively stable, so investors will be more comfortable psychologically, and at the same time, earning less can also bring benign investment. Fourth, look at the picture and analyze it. If you can't read the chart, you can't make foreign exchange investment. Many technical drawings actually don't look as difficult as you think. As long as you understand the meaning of each part of the chart, you can analyze it together, find out the support points and pressure points, and determine the appropriate trading signals.
