数学期望是概率学的一个基本概念,简单来说,数学期望就是同一行为大量、大范围重复后得到的平均值。不是正期望的行为就每次一定赚钱,也没有人能够知道某一次能不能赚钱,但是当这种行为重复到足够的数量,整体的结果就是正的。随着交易数量的增加,交易的概率接近50%It's the same as flipping a coin.
Simply put, the trading system tells you when to open and close positions. For example, the Golden Fork Dead Fork operating system and the Golden Fork do long; Short selling during a dead cross; Wait until there is no trading signal. This is a complete trading system. The trading system should include: screening of entry points, setting of stop loss and take profit levels, and fund management.
如果是按照交易系统的要求来分析市场,而不是去预测市场,要用趋势逻辑来指导交易,任何妄图准确预测市场的行为都如水中捞月。我们需要知道的,对我们来说最为重要的则是--The mathematical expectations of our various operations are the foundation of trading.
