炒股，指倒买倒卖股票。炒股的核心内容就是通过证券市场的买入与卖出之间的股价差额，获取利润。
Stock speculation refers to the buying and selling of stocks. The core content of stock speculation is to make profits through the difference between the buying and selling prices in the securities market.
股价的涨跌根据市场行情的波动而变化，之所以股价的波动经常出现差异化特征，源于资金的关注情况，他们之间的关系，好比水与船的关系。水溢满则船高，（资金大量涌入则股价涨），水枯竭而船浅（资金大量流出则股价跌）。
The rise and fall of stock prices change according to the fluctuations of market conditions. The reason why stock price fluctuations often show differentiated characteristics is due to the attention of funds. The relationship between them is like the relationship between water and boats. When the water is full, the boat is high (when a large amount of funds flow in, the stock price rises), and when the water is dry, the boat is shallow (when a large amount of funds flow out, the stock price falls).
中国股市交易规则
买卖股票的数量也有一定的规定：即委托买入股票的数量必须是一手（每手100股）的整倍数，但委托卖出股票的数量则可以不是100的整倍。买入或者卖出的价格必须是收盘价上下浮动10%的范围才有效。
股票交易实行价格优先、时间优先：股票连续竞价时段，因为有许多投资者可能同时买卖同一只股票，所以交易所制定了“价格优先、时间优先”的原则。如某只股票现价5.66元，如果甲投资者此时输入5.66元的买入价，而乙投资者同时输入5.67元的买入价，则乙投资者的申报优先于甲投资者的申报成交。如果大家申报的买入价格相同，则谁先输入买单谁先成交。卖出股票亦如此。某只股票如果现价是5.66元，甲输入5.66元的卖出价，而乙同时输入5.65元的卖出价，则乙的申报优先于甲的申报成交。如甲、乙输入的卖出价相同，则谁先申报谁先成交。这种情况在某只股票股价突然飚升或突然急速下探时更加突出。
股票市场技术分析
技术分析，是通过股票分析技术对股市行情进行研判，如k线形态分析，技术指标分析（均线系统、kdj、布林线、macd、移动指数平均数等），有道氏理论、k线理论、各种指标理论、波浪理论等著名股票分析理论。是从证券市场研究的角度进行分析研判的。基本面分析。就是通过上市企业的经营状况，财务报表、主营业务的市场前景发展情况等分析的。常关注企业的行业成长性、企业的资产负债报告情况，企业的当前盈利状况，经营状况等。另外，还有消息面分析。通过得到的消息信息来判断未来企业的发展。这里的消息，一方面是来自政府的政策，一般叫政策面。例如，国家出台政策鼓励新能源技术。那就一定会对新能源技术企业的股票形成利好，从而推动股价的上涨。还有来自市场内部的，也包括内幕信息。如，企业重组消息。企业盈利消息。企业重大亏损消息。
China Trading Rules
There are also certain regulations on the number of stocks to be bought and sold: that is, the number of stocks to be bought must be an integer multiple of one lot (100 shares per lot), but the number of stocks to be sold may not be an integer multiple of 100. The buying or selling price must be within the range of 10% above and below the closing price to be valid.
Stock trading implements price priority and time priority: during the continuous bidding period of stocks, because many investors may buy and sell the same stock at the same time, the exchange has formulated the principle of “price priority and time priority”. For example, if the current price of a certain stock is 5.66 yuan, if investor A enters a buy price of 5.66 yuan at this time, and investor B enters a buy price of 5.67 yuan at the same time, then investor B’s declaration takes precedence over investor A’s declaration. If the purchase prices declared by everyone are the same, whoever enters the buy order first will be executed first. The same is true for selling stocks. If the current price of a certain stock is 5.66 yuan, investor A enters a sell price of 5.66 yuan, and investor B enters a sell price of 5.65 yuan at the same time, then investor B’s declaration takes precedence over investor A’s declaration. If investor A and investor B enter the same sell price, whoever declares first will be executed first. This situation is more prominent when the stock price of a certain stock suddenly soars or suddenly drops sharply.
