Matters needing attention in futures trading:
First, fully understand the trading system of trading varieties.
The futures market's margin system, compulsory liquidation system, position limit system and daily debt-free settlement system are all different from the securities market. A full understanding of the trading system of the futures market is of great help to understand the sources of risks in the futures market and how to control them.
Second, strict fund management.
Generally speaking, unprofitable overnight positions should be controlled below 30% of funds. For newcomers to the market, judging the ups and downs of the market should be placed in the second place, and fund management is the first level. It tests the rigor of investors' thinking and operation, and the randomness of operation is an important reason for the failure of futures.
In reality, futures experts are not more accurate than novices, but they are more experienced in fund management and operation skills. Other investors even use the stock operation method to do futures and Man Cang trading. In the futures market, the result of this operation is that as long as one mistake, it may be wiped out. Therefore, investment in the futures market should adhere to the principle of fund management and not put all your eggs in one basket.
Third, stop loss in time when the direction is wrong.
It is common for investors to speculate in stocks as "shareholders |", mainly because they think that the risk of the stock market is small and they will not lose money if they fall again. There is no such luck in the futures market, but some investors feel that their positions are light, or some are profitable, so they can't strictly follow their own instructions or simply don't think about stop loss. This is a big taboo for futures.
Fourth, we are afraid of delay if we are not afraid of mistakes.
Some investors are always afraid that a stop loss is the highest or lowest point and hold the idea of keeping another one, but the changes in the futures market may change rapidly. If it is an extreme market, it may be doomed not to stop loss, but stop loss can at least give them a chance to continue trading. In short, it is part of the stop-loss concept to make futures.
Fifth, seize the opportunity to short.
Futures trading is a "two-way street", which can be long or short. Limited by the traditional thinking of stock and real estate investment, ordinary traders tend to accept buying before selling when they first come into contact with futures trading, but it is difficult to understand selling before buying. Therefore, they are more interested in doing more and are always a little uneasy about shorting, thus missing many opportunities to make money.
6. Beware of being afraid of winning money and dare to lose money.
This is the most common mistake made by newcomers in the market. When people make a profit, they are often afraid of being spit back, so they are eager to make a profit and leave. As a result, they didn't make much money later. When you lose money, there is always an illusion that you can earn it. I may have earned it back several times before, but once I didn't, I would leave the futures market.
Seven, don't become a gambler.
Psychological investment in futures market with gambling size is easy to fall into blindness, thus ignoring the basic factors behind the market ups and downs, such as capital supply and demand, market psychology, macro changes, chart signals, large-scale methods and so on. Market analysis depends on random speculation, and investment direction depends on inspiration. This is the so-called blind riding a blind horse.
