Do Banks & Hedge Funds Use Technical Analysis?

Also what kind of TA do they use if so? Do they use indicators, trendlines, etc.

The fund I'm at has a trader that specializes in it, but not sure how much weight they put on it

Hasn't technical analysis been proven to not work? A Random Walk Down Wall Street says so, but maybe someone else has contradicting evidence

Some traders use TA but it's probably more product dependent. TA is a scam in my view, and given the amount of data you have at a bank regarding flows of capital and research etc Im not sure why youd use TA like some retail FX day trader.
Particularly hilarious when I see people using TA to explain past moves and predict future moves when they clearly have no idea what they are talking about.

Technical Analysis is a very broad category. There are certain chart patterns that work well for predictive pattern recognition, on a statistical basis. If coin flipping gets you 50% odd of being right over 100 trades...Technical Analysis, performed by a user with some skill and experience, can maybe get you to 60-70%. However, "technical analysis" is a very broad term....there are some patterns that work very well for certain markets...and other technical patterns that don't work at all...and it takes experience to know which is which...so...does that mean it doesn't "work"
