Trading is a pattern recognition game. With TA you don't need to know maths but if you understand how the indicator is created, you might be able to use it better.
Hey,
I slightly disagree.
You may not "need" to know mathematics to create a candlestick, but you will struggle to compute a Kaufman Adaptive MA or Sine Weighted MA if you have no understand of maths whatsoever.
Of course, most software packages can compute and plot data for us, but it's like saying one need not to study maths at school so long as he will have a calculator as an adult.
Besides, TA as a "pattern recognition" discipline is a bit oversimplified. I am sure those who build artificial neural networks would agree.
But, if the underlying idea was that one need not to know maths to do some TA and make money in the markets, that I agree with.
To a large extent it depends on your personality. If you are good at math and have a curiosity on how the presentation of information you will attempt to recognize patterns on, you will likely dig in deeply and do your own custom tweaks.
However, you don't "need to know" how the stuff is derived to learn the art of pattern recognition as your trading tool.
