TA is basically a chart-reading technique that applies key levels on a chart to show possible reversals. Support vs. resistance, fibonacci, elliot waves, moving averages with crosses at certain time frames. The most popular one you will find out there is the 50MA and the 200MA and how they are implicated in price movement. Whether they are day or weeks matters not...Someone will always find a way to apply meaning to those two MAs. Keep reading articles about trading, and you will adsorb more and more about all the TA stuff.
Funny thing about this post is many people around here know their approach sucks in one way or another yet still get defensive because the post doesn't adequately represent their beliefs.
What all the funnymental critics don't get is that the funnys determine long term trends. TA short term. Especially intra-day, reversals, new high, new low. So day traders like myself could care less about auto sales (unless you trade F, G, TSLA etc) industrial production and all the other secondary eco reports. Of course FOMC/NFP and nowadays CPI have to be watched keenly on their respective report days. But once the major reports are out of the way intra-day it is all about support and resistance levels, volume, IB breakout/breakdown, etc. Fine to look at what happened yesterday, last week, last month even last year to cause us to be at current levels but TA explains currently where we might go .... before the next news event happens tomorrow, next week, next month, next year.
...and you only get rich from short term trading. If one only thinks longerm he needs deep pockets to make some money, because the returns on longterm are not huge enough to be a hero from zero. So TA is the thing to concentrate on. My opinion.
Pfft, every strategy works as long it is part of a good position sizing method that will let your runners run.
