Thanks for sharing the link.

Now it is more clear that everything and anything is semi art.
My point is applying math on an art will down grade the art.
Trading chart is an art. Applying math model on the chart means burning the sandal wood and selling the coal.
I prefer to sell the sandal wood instead of coal. I wont degrade the art.
Chart reading is an art. Math model dilutes the art. Math model can never ever match the art of manual chart reading.
You people sell coal and trying to convince the sandal wood sellers that earning 2% per month is the normal. Sandal wood sellers earn lot more than that.
In democratic world majority wins. 99.99% of traders sell coal. You win.
