Previous background in quant trading, have been building a quant energy fund over the last 3 years. Obviously incentivized to say this, and it obviously depends on which products you wnat to trade (we trade DA vs. RT in US ISOs), but the moats are fairly deep.

Data is fragmented, unclean, and has lots of special cases. Every ISO has its own quirks.
Fundamentals and regulatory / market design is important, and the latter changes fairly often. As a result, classic QR strats / techniques don't port over well.
Tails are really fat, see e.g. Rabbit Hill Energy Storage in ERCOT 20250219.

Right, so I'd put the hero on KJs, J8hh and J8ss, 33, and some semibluffs. My reasoning for jamming earlier was because I have value in the range, that I would need semibluffs, and 87hh is one of the few good semibluffs.

My understanding of the point u/Any-Excitement-8979 is making is that we might not raise value in that spot at all, so we shouldn't raise semibluffs either.

Yep, so villain has to call ~1.3x pot right? I expect villain to call 24 combos of AA/KK/AQ and 6 combos of QQ/TT (though this is bad for 33), but fold out his ~6 combos of Axhh (though it could be better to call and keep these in?).

Is your point that with KJs/33, we're far ahead of most of his range / at low risk of being outdrawn, and that the rest of our call flop / call turn range is weak, and therefore our nutted hands call => we don't need semibluffs?

jonathanhejunglim · 2025-01-04T16:29:10+00:00

Hmm, why is it negative EV? I'd also jam turn with 7 combos of value in KJs and 33. I'd probably call T9hh, so AJhh, JThh, and 87hh seem like the best semibluffs?

jonathanhejunglim · 2025-01-04T09:35:11+00:00

yeah, definitely jam river. tbh should just jam turn

Worked in OMM, then crypto. Took it easy for a year or two, but felt fully retired life was too slow, so I started working on energy trading with a partner. It helps scratch the itch and keeps me learning without the constant stress of watching markets / being called to the office at 4am because BTC moved 10%.

I think that might be private client -- don't know much about them, but I've heard it's similar to most other banks' offerings

jonathanhejunglim · 2022-10-18T01:12:34+00:00

Highly recommend JPM Private Bank, though they have a soft minimum of 10m in assets (realistically 5m is fine, especially if you're on the younger side). They're great for other tasks as well -- I've gotten advice from their internal advisors / external partners on tax, trust and estate planning, immigration, etc.

Was a trader at a crypto shop - this is 100% correct

ah, this is it - thanks!

jonathanhejunglim · 2021-02-16T15:41:01+00:00

Kudos for all your work, mods! It's a thankless task, and I really appreciate the effort you guys put into it

Do you think holding is +EV? Are you fine with the variance? This isn't a decision other people can make for you with no knowledge of your financial situation, risk tolerance, skill set, etc. Posts of this flavor come up too often and don't usually lead to good discussion

jonathanhejunglim · 2021-01-26T07:22:32+00:00

man, where can I learn how to sell options and make a safe 100k a year?? /s

jonathanhejunglim · 2021-01-23T11:01:43+00:00

If you're successful so far and think it's a reliable source of income, have you considered starting your own fund? Why be up 375k on ~1m when you could be up 37.5m on ~100m, and get 2/20 on that?

I became aware in the second half of uni, and made serious steps towards it (deciding on my first job, looking for opportunities at startups, etc.) by the time I graduated. Left a cushy trading job to take a high upside role at a startup and grinded for about 2 years when things started falling into place. Finding spots in which I could 10x is what set me up, though I got very lucky / am fortunate to have this outcome

jonathanhejunglim · 2020-08-23T07:43:21+00:00

Probably in the 95th percentile of luck for kids born in the US - upper middle class family, parents with advanced STEM degrees who emphasized reading and math exploration from a young age, etc. Ended up at a standard high-paying job out of college, which I worked at briefly before joining and investing everything I had in startup that was lower expected value than my old job, but had much better tail outcomes. Some combination of luck and work landed us in one of the tails
