Basically, what you expect TA to do may not happen. It is definitely true because the reality is that markets do wild moves that we have no idea that it would do. I hope that it would do what we expect it to do but the reality is that we should end up with something that would be a lot more realistic and predicted so that we could make some profit and that would be great but we are not seeing that at all and that is the reason why we are losing money most of the time as well.
Yes, it is not something great to lose money but if it was predictable then we would all make a profit and that is not going to happen, if we all make money then who are going to lose money to us while trading?
The situation with TA is that when people do not use it, they make more losses, and when they use it they still make a loss. Which means that it is not guaranteed that you will profit when you use it, but it is also nearly guaranteed that you will lose when you do not use it. This is why people suggest TA, not because you will profit with TA 100% guaranteed, but it is nearly 100% guaranteed to lose without it, like at least 90%+ guaranteed. This is why TA is not a method of profiting, it is a method of avoiding a loss.
This is not something people understand very well, many people think they can make a profit using TA and shocked when they do not. And that is a big deal because there are too many people who are here to keep making a ton of profit, which we all know you can't constantly do that. So people should realize it is a method of avoiding a loss, not making a profit.
Like most of the time the biggest problem people have when it comes to TA are their own expectations, as you say the majority of the people that use TA still lose their money, but then this brings the question of why to use it? Because all of those that do not still lose their money, TA is not a magical formula to make money instead it is a way to protect your capital so when the market finally begins to go up you happen to still have most of your capital intact so you can get all the benefits from such movement.
