but don't you think that over an ER trading TA is risky? Anything can happen right?
If we lived in a perfect world, numbers would be known by everyone
at the same time.
Insiders would follow the rules, and anything could happen.
Reality is that insiders and friends, hackers, HFT firms got numbers days, minutes or even seconds before everyone and what are they doing ? They abuse the majority and buy / sell before ER. So you better be with them rather than with the majority.
TA and price action show what insiders / big hands are doing or trying to do secretly: accumulation ? distribution ? Fake movements and manipulations? Real intentions?
Remember,
the tape tells all. Price and volume don't cheat and just reflect confidence / fear about a company, a sector at any moment.
That is why I like to follow small / micro caps. Less cheaters, manipulators to try to abuse you.
Generally I don't know what these companies are doing / producing and I don't care. Price action tells you to enter / exit without guessing about business / prospect / future.
On the other hand, if you trade companies you know, you may not stay neutral, you got tons of "feelings", "rumors", "news" and this is not the good way to make money.
Again, I recommend to everyone who wants to make money to read, reread and analyze "Secrets for profiting in bull and bear markets". Still true after 30 years.
