That's as simple as it really is if one can free oneself from old beliefs and convictions if they don't mesh with available facts, open ones mind and is able to identify what really counts while ignoring the irrelevant rest.
It ain't rocket science that's for sure.
Understanding how to trade net profitably has nothing to do with predicting.
It's about no more than skewing the odds in your favor by identifying a method with an edge that you clearly have when trading pullbacks in trends or reversals in ranges, accepting that you'll be wrong and have losing streaks, not letting that deter you from trading your plan, keeping a tight control on losses while accepting in profits what the market will give you and hey bingo you're set.
And then one can leave it to the naysayers to post idiotic threads like this about stuff they don't get and can't get to work even though there are abundant examples of people who made fortunes through some of the simplest systems you can imagine that TA has to offer.
Or isn't a billion enough that John Henry made lol through simple trend following.
Best part is people posting this negative, entirely uninformed nonsense with absolutely no connection to reality can't even offer any alternatives lol, just like nine predicted, this thread has now run almost 30 pages with absolutely nothing of any alternative substance whatsoever on offer.
Not even close.
Those who can get on with it and do, those who can't pose around posting nothing but smoke and mirrors trying to at least look clever to the entirely gullible desperate for a holy grail.
Or do you or anyone else want to bet we'll ever hear anything concrete from the OP or any of the other naysayers as an alternative to TA for trading, not long term investing where fundamentals may well have their justification for those so inclined.
