Realizing the AI-human hybrid and Centaur in financial modeling.




Time to back off. Been pushing this notion that the signed order book (SPX large lot options transactions) is where edge resides ... and everything else we're accustomed to talking about ... is a mere shadow of edge ... measures of market activity that fail to withstand quantitative validation. It's a "Which came first question: the chicken or the egg?" Two points and then I'm going to shut up on this: 1) no desire to offend anyone who embraces and is attached to what works for them. Respect. The whole FinTwit space ... at its best ... is essentially about idea discovery. Discourse. 2) pushing the order book as the sine qua non might appear to be promoting a perspective that is single factor ... too narrow. Not so. Trading the order book is actually multi-factor - e.g. imbalance, flow (signed volume, aggression), book convexity, order distribution, bid-ask spread dynamics, distance from VWAP. That's it. Stood up ... said it ... now sitting down. Do your thing. ________ Reminder: I'm a surgeon ... not a credentialed financial guy ... so take everything in this account as a muse ... just thoughts ... nothing more ... with little value exceeding an occasional, "Hmm, now there's a thought."



@TailThatWagsDog But that's just plain wrong. If you have Gamma you can calculate Charm heatmap and that beats LOB any day. Charm flips (for ES/SPY/SPX) and Charm gradient are far better trading tool. For Gamma it's almost useless if you use naive GEx
