@Same Lazy Element true but garachen (someone who has a masters in mathematical finance) and owns a real trading company (not trading arcade) that does a lot of algorithmic trading laid out a process for how he teaches manual trading based off of intuition in a thread here:
https://www.elitetrader.com/et/threads/a-path-towards-profitability.236208/
He also said:
“That's right. This method of manual trading I presented purposefully has nothing to do with math. That's why I said math is not required to be successful.
That doesn't mean that modeling intensive approaches don't work. Of corse they do but from my experience the edge captured by a manual trader is quite a bit larger than what most algorithms are capable of.
Yeah. I can price a Bermudan swaption off the Mexican yield curve which was a great skill for when I was a quant but not so useful for manual trading.” -grach 2012
considering he mentions that he expects his manual traders to average 7 figures a year and he said his strategies as a whole (automated and manual) have a sharpie ratio of 7-9 that’s pretty good for just “guessing”, no? But garachen does say that a high degree of “mathematical intuition” is necessary for all trading even the method he lays out which isn’t math based.
I just wouldn’t be so quick to knock an approach that involves watching the book/charts/correlations/news and trying to sense out momentum and mean reversion. That’s how Nav Sarao traded and he did 8 figures a year for many years (and recently) and averaged around 100,000 contracts a day in the ES. I BELIEVE (maybe you know someone that actually knows) that this is how Igor oystacher traded/trades and he was one of the biggest traders in the ES (but he also owns 3red which does a lot of quant/algo stuff from what I understand)
but garachen did say
“I don't hire people to teach them to manually trade anymore because generally there's a better use of everyone's time, but I'm not opposed to them picking it up.” -in 2014
other posts show him being a bit more bearish on manual trading, that it’s gotten harder but it could still be done at a high level. I asked him some stuff about intuitive manual trading a few months ago and he didn’t say anything along the lines of “that can’t be done anymore”.
I’d bet that DRW still has people trading in the old school manner at a high level but they probably don’t hire people to trade like that anymore. From what I understand the top places don’t pay out that much (I’ve heard 25-50 percent for jump, drw, and the like) so I don’t think it would be easy to retain the best manual traders. I don’t think that’s the primary reason for so much algorithmic trading among the top prop shops just that it could be a small contributing factor. Algorithmic traders benefit from their infrastructure, tech and teamwork so it makes sense that you could still retain some of the best quants with a lower pay out. Plus if they decide to jump ship they get to keep their IP. Just think that those could be some reasons for the quant/algo revolution among prop shops (I’m an outsider but that’s what is happening from what I can gather) outside of quantitative approaches just being vastly superior to discretionary manual.
but yes it’s a bit silly when you see the quant naysayers. I like the “they’re just hired to impress potential investors” line, when top prop firms have so many PhDs (from what I’ve heard and seen on LinkedIn) or people with a masters in mathematical finance and zero investors. They’re there because they generate alpha!
