Sorry if the question sounds rough. It's not my intention to devaluate something I've not yet understood like Quantitative Finance.
So to keep it simple:
- is Quantitative Finance a science, like Math or Physics?
- Or is it something more similar to Technical Analysis, but with much more math into it?
I know Technical Analysis is not a science, but an attempt to apply math to past financial data in order to find a way to predict the future movement of the same financial data.
Obviously things can mix up and create confusion.
Formulas like a simple Moving Average are real math and they are still in the field of science. It's when people attempt to apply a moving average to predict the future that they trespass the border of science to enter the field of empirism (that unfortunately in worst cases might even lead to charlatanism).
It confuses me even more when I read on Wikipedia about "Algorithmic trading quant"
Often the highest paid form of Quant, ATQs make use of methods taken from signal processing
Well A T3 (the so called Tillson's moving average) comes from signal processing (low pass filter/differentiators digital filter) and it's used in Technical Analysis.
So if someone uses a simple Moving Average is a Technical Analyst, but when he uses a T3 moving average is a Quant, because the latter one is more complicated to be calculated?
