A 'hundred' years ago the guys who thought up typical TA concepts as we know it would have made a killing due to the fact the vast majority of traders being ignorant of TA concepts, they were just dumber or ignorant on how to trade technically, prolly the vast majority carried a rabbit's foot in their pocket.
As time progressed and word leaked out of TA it may have even worked better due to it being self fulfilling, that is until smarter traders began to capitilize on trading against it.
Then authors would have found it more profitable to sell the books than it was to trade.
Now every Tom Dick & Harry is aware of TA and when TA works and when it doesnt work is 50/50, per chance and coincidences. Conventional TA has no edge.
Thinking outside the square is required these days.
To be fair, it depends on how you use it.
Peter Brandt, he of classical charting principles, openly says chart patterns do not provide an edge, trade and risk management do. His long term win rate is below 50%, low to mid 40s I believe. He reckons 85% of his profits come from 15% of his trades, which tells me he is pretty good at trade management.
I have no idea if any of these metrics apply to day trading, I suspect they probably do for some styles. Successful scalpers, and I know one personally, have win rates around 90% but crap R:R that I have difficulty living with.
I used to swing trade successfully using MACD, truth be told I spent upwards of 1000 hours that first year working purely on trade management. Moved on, now I’m back to day trading, not yet successful, but it is one of those things I want to accomplish before I die.
If anyone trades successfully with chart patterns, or indicators, those are not the edge. They give a clear structure on which to build discipline, and trade and risk management.
I’ve been trading long enough to recognize that unless you are exploiting a short term market imbalance, it really is a coin toss. You put the odds in your favor if you can spot a trend, there are research papers attesting to this, and that trend can be on anything from a 1 minute chart to a daily, weekly or monthly chart. I trade the 1 minute chart, Alexander Elder wrote of a chap who traded the monthly charts and spent his time going around the pro ice skating circuit with his granddaughter.
When I was trading FX, I recognised the mean reverting tendency and used a simple oscillator and data analysis to provide structure. That doesn’t apply to what I trade now, the DAX, which is why I follow this journal. I use a different method now, and the pig I’m wrestling with in day trading is my mind; you don’t have the distance swing trading gives you, so you wrestle with demons all day long. That aside, I have a pretty solid method.
Don’t discourage the man, if he has a structure he believes in, which is more than most people here have, then all he needs is risk and trade management to be successful. If he has those, there is nothing to stop him from making a living trading.
Only idiots lose money in bull markets. It’s ranging markets that separate traders from the rest.
