"Dark side of technical analysis"

http://adamhgrimes.com/blog/dark-side-technical-analysis/

What he writes rings 100% true to my experience as well, for me, technical analysis was a phase I went through about 10 years ago, with very little to show for it except robust skepticism and the demand for quantitative proof of edges!

Hello Simon,
very interesting! Strange that you have so few replies (actually there was a second one from Market Meat).
May I ask, with which general strategy you try to get the edges nowadays?
Best Regards

I am focusing on providing liquidity during predictable (or at least recognizable) situations where someone, for whatever reason, must trade at any price.

Hello Simon,
as I am still a beginner, could you give some examples of these reasons.
Thanks in advance!
Best Regards

Examples might be when they receive a margin call, or when they must rebalance their exposure to some fixed ratio or leverage, or simply when they must get a certain number of shares executed.

Simon,

So how do you find/detect desperate people/institutions? I'm guessing folks don't exactly want to broadcast that they are between a rock and a hard place.

This is an example of a predictable situation. There are others, like options expiry strike pinning, options' dynamic hedging, leveraged statistical arbitrage unwinds.

Also, referring to Market Meat's post (which he may or may not be reposting?), yes, these effects are also great tell-tales, and there's some literature on HFT "momentum ignition" referring to price movement on short timescales.

Thank you!
