[Y^^]E: Check the past (先察已然)
If you want to know the future, check the past first.
慾知未來 先察已然
- 明心寶鑑 省心篇上
Who controls the past controls the future. Who controls the present controls the past.
- George Orwell (1903-1950)
These sayings are not about the financial market. Nevertheless they also come to mind when I think of the financial market.
A lot of participants use the historical data to price financial products or to forecast the future.
Of course, the past does not repeat in the future. However, it does not mean the past is useless. The important thing is how to use the historical data and the record of past events.
