I certainly wasn't being condescending, or didn't mean to be at least so if it came across that way I'm sorry. And nothing I say is so I can sell a service. I'm a poster on a forum just like you are, just chatting. If people want to make money trading volatility products I'm sure they will stumble on to a few of the subscription websites that are out there (and I think they will choose the one with the best and most consistent returns available

)
As to what you're saying about how institutions use TA to trade volatility, again that has nothing to do with XIV. The XIV or VXX are not volatility, they are only a part of what that word means.
If you feel the need to draw lines on an SPX chart, or a chart of the UVXY, you've missed the entire point of how these products work. And by you, of course I mean the guy that posted TA charts doing exactly that. Not you you, I mean anybody who does that. Waste of time, totally worthless.
I agree 100% that TA is useful in trading volatility in several forms. In stock trading, option trading, day trading, futures trading, what have you. I'm simply saying, in the form of the XIV and VXX,
in those specific examples, TA is worthless.
Now I'm not saying this to be condescending so don't be sensitive. I'm simply saying, if you think TA is useful in trading the XIV or VXX, you are simply mistaken. That is all. The correlation is far too coincidental and weak to be of any use.
There are several far more reliable places to be getting trade signals. Why anybody would go to the 10th in line when you can just go to the front of the line is beyond me.
I'm am in no way against TA in many types of trading, including volatility trading. But specifically the XIV? No, TA has nothing to do with the formula for how it's price is derived or what
CAUSES it's movement.
Correlation does not imply causation
