技術指標背離 ?
Deviation ?
今天有位同學問我,
技術指標背離代表什麼意思 ?
Today, a student asked me what "deviation" means.
技術指標設定下限為 0 ,
股價再怎麼跌,指標最低跌到 0 ,
不會變負的 ,
所以跌到後來指標就鈍化,
即所謂的技術指標背離。
Technical indicators are typically set with a lower limit of 0. This means that even if the stock price drops significantly, the indicator will not become negative as long as the lowest point is still above 0. However, as the stock price falls, the indicator may become less sensitive and less useful, which is referred to as deviation from the technical indicator.
這是公式設定必然的道理,
而非隱含了什麼不為人知的市場轉變。
只要把下限拿掉,
讓下跌可以跌到負的或無限,
就不會出現指標背離。
數學不太差的人都能理解這個道理。
This is the result produced by the formula, and does not imply any unknown market changes.
By removing the lower limit and allowing for negative and infinite values as the stock price declines, there will be no deviation in the indicator. This is a fact that can be understood even by those who are not very proficient in math.
