@tak3sh8 i assume he means Pr(s_t | s_{t-1}, a_{t-1}) is "causal" in some sense. think this is true of any RL environment tho?

Wow Yuji Nakatsukasa is really a legend of rational approximations he already solved basically all the problems I was looking for in ML

You (trades a PA): - retail scum - backtesting technical indicators😂🫵 - total punter - part of the 99% that fails Me (trades a PA but I made a single-member LLC and landing page to call it a "firm"): - highly sophisticated - real professional - "leave it to the big boys kid"

The reason why this is a strong signal for LARPers is because unless you've worked in the industry then you don't realize that the bulk of complexity in quant trading mainly shows up in the portfolio construction/tcost opt stage and not signals
Jessica Nutt@JessicaNutt96

@SouadH9 @GfI_Himmelreich @ordinaryepsilon @macrocephalopod probably no stronger signal of larp than a strong bias towards complex methods. if you've worked at any of the big successful hedge funds you've seen how much money can be made with careful arithmetic and the occasional OLS.

Thursday morning quant interview question. A junior comes to you with a ML model trained using walk-forward validation, and shows the following backtest, created by stitching the out of sample periods. What are your comments? What might they have done wrong, if anything?

@cmuratori i think he tried really hard to help them debug their software platform and they wouldnt even talk to him. i'd be pretty annoyed too (maybe not this annoyed)

Aight aight, I will make myself more clear. Let’s assume that passive orders of some other participant can be perfectly identified in the book and I have measured markouts of trades against these orders either in previous prod or at least in backtest. Now…

@HFTBread @elricmann I mean the fence in the post, which is "0 instructions and "dirty memory" is insufficient. maybe other more experienced expensive ones work, but they will be more expensive than using acquire/release or (rarely) cas
