Speaking of stop loss, human greed instinct makes every investor unwilling to lose a few points, let alone win a few more points. Some investors missed the opportunity when they reached the stop loss point, some investors regretted temporarily and increased their positions in full, and some continued to take risks after the losses increased. Investors who cannot use stop loss correctly can avoid these phenomena by using programmed stop loss.

There are certain risks in the foreign exchange market. You must take strict precautions and don't regret it when you can't make up for it. Remember to have a peaceful mind, use real profit and loss stops, and use your solid basic skills and technical analysis capabilities to travel in the "Huihai" in a planned way. And if your basic skills do not meet the requirements, please improve yourself first. We know that the formula for return (over time) is very simple, R = return over time/principal. As long as each transaction is carefully recorded, "period income" is not difficult to calculate. If you only use medium-term returns to measure trading levels, you'll stop there and the problem won't exist. If it's positive, you make money; if it's negative, you lose money.

This is a problem because the principal needs to match the income, and there is a prerequisite: frequent withdrawals. In the case where the principal keeps changing, calculating the principal as the denominator becomes a bit more complicated, which is problematic. I think this is the core issue of the nut case. But this is not actually a problem. The banking industry has had such a method for a long time. It is called an accumulator, and it solves the problem of how to calculate interest. The problem is similar: for a current account, money flows in and out, and the balance keeps changing. How do you calculate interest at each closing? That is, how much principal is used to calculate interest?
