Does Any Technical Analysis Work? (Part 5)
Posted by Mark on December 3, 2019 at 07:16 | Last modified: April 22, 2020 10:27Today I continue with a sample of internet opinions on whether algorithmic trading with TA can actually work.

I’ve heard this many times and find it to be a compelling, but not ironclad argument. If I had a large chunk of money then I could certainly turn it into millions. If I had little money, then I might still benefit from selling to others for point-of-sale profit while I execute it myself and make a high return percentage on a small amount. Alternatively, for the sake of diversification I might never want to trade it in large size. Since I could not count on making too much money from this one system, I might as well sell it to others to get some guaranteed money while I continue work on developing others.

I’ve written much in this blog about optionScam.com. Like me, this person has also observed the financial industry to have some nefarious (see third paragraph here) contributors.

I’m not a conspiracy theorist (see third paragraph here), but given that a decent amount of misconduct exists in certain segments of the financial industry, I think we need to acknowledge the possibility described. I think the only way to know with more certainty would be to work in the industry proper—maybe for multiple firms to gain perspective on tactics used by a large sample size of institutions.
I will wrap up these comments next time.
