Quote from dtrader98:
Not true at all. If you flip a coin and see a common pattern, does that mean you know what to do? No.
It means if you've done your homework beyond looking at many visual Rorschach blots, and perusing the few cherry picked examples from the many books you'll encounter on your TA journey, you should have an expectation of what might happen, and you should plan on what you will do depending on what that outcome is.
How good is your expectation, well, when you are done with reading all the myriads of common subjective TA books, you can start adding backtesting, statistics, and most importantly, money management to your trading vernacular.
