Why are moving averages so easy to use?
Because it is an average line, it has exactly the same meaning as Dow Theory.
Therefore, when you include an envelope, there are points where it becomes easy to see the shape of Dow Theory.
Also, with moving averages, when prices deviate, they are immediately reflected by the average line.
The more you think about analysis from a mechanical perspective, the more it becomes "useless."
That is because there is no such thing as absolutes in that analysis, and it cannot exist.
As if there is a Holy Grail in the market,
it is only a counterfeit Holy Grail that changes depending on who uses it.
In the end, a Holy Grail is
a logic that is extremely convenient for your positive analysis and negative analysis; nothing more than that.
That is the only logic worthy of a Holy Grail and, thus, becomes market perspective.
