I think I understand why you hate TA so much surf. Its because its not a sure thing. You are absolutely right that something that you see in charts over and over again might never, ever work again. But when you see it happen over and over again, does it not make sense to try it a few times to see if it can work again in the future?It all goes back to what u use it for. Ta is descriptive, ta is not predictive.
Using TA to describe is the correct use , using TA to predict either the next moves or a winning percentage of a series of trades/moves is fatally flawed thinking.
DOM and bid ask occur BEFORE price is created therefore it makes sense to use. This action is the cause of the effect called price.
Studying the Effect to determine future Effect is lacking even the most basic proper logic.

I mean when you go start your car in the morning, there is no guarantee that it will start again as it did the day before. Maybe the battery is dead, maybe there is no gas. But when you choose to go to the mall, you are using the descriptive power of your car getting you to places you wanted to go before, so now you're using it to predict that it can do so again this time. You don't think twice... you don't call your mechanic in anticipation of it not working, you simply get inside and start it.
Most men marry so that they have access to regular sex. (maybe they like meals more.. I'm not sure... LOL) Is there every a guarantee that your wife will have sex with you tomorrow? Maybe today is the last day and this pattern will never repeat. But when you get married, you are using the pattern of married women having sex with their husbands as a way to predict that she will have sex with you in the future. If you wanted a guarantee to have sex tonight, then perhaps you need to have a few lined up just in case your wife says no, but having a wife is a pretty good guarantee to sex.
Likewise, patterns from the past are a pretty good guarantee for the future when it comes to trading. It might not happen with even 80% reliability, but when you figure out a risk:reward ratio that is positive, you've got an edge!
