If you’re still interested in all this shit but don’t know how to actually get started after brainstorming, try doing it manually to start. Most people seem surprised to hear anyone’s tried it manually, but after reading this article it should be clear that marketmaking does not require you to be at the top of the book. “Pure” marketmaking is all about mean reversion, and although doing it at very rapid pace for small spreads is usually the most profitable, the concepts are broadly applicable at any distance from mid. David is not only a gifted medium he has an amazing gift for writing. I have read many books about the spirit world but I struggle to believe alot of what other mediums have written.. It feels exaggerated, or just too bizarre to be true. What an amazing gifted man David Holt is. To let us see and understand his gift (which he does so well in the book) is fantastic. Born and raised in Bolton myself it was like reading about someone I know although I have never met him - currently looking for dates to see him! There are infinite other ways you could try and calculate or derive fair price, but remember that you always have to be able to unload your inventory. If your fair price model has your quotes skewed too much higher or lower than everyone else, you’re unlikely to get filled equally on both sides and your model will end up costing you money no matter how superior you believe it is.

Deciding how wide to quote is one of the most challenging and multilayered questions I’ve encountered in my life, probably because I’m bad at math and staying focused. Let’s give it a shot.The upside is that if you can ad-hoc decent solutions, there’s a good chance you can make good money even if you’re miles off from the undiscovered textbook solution, because everyone else probably is too. If you’re wondering, my first model was a gridbot with periodically updated logic for application that ended up behaving a little like the example model. My latest is less different than you might think, but the small changes add up to massive differences. So keep trying new shit! There are academic papers on this topic, formulas to follow and all sorts of highly technical and mathematical models for the ideal marketmaking models, but I never learned any of them because I am relatively dumb. So here is where we part ways with the academically correct solutions and gigabrain quant models so we can instead talk about rough estimations and subpar heuristic solutions because that is what I’m familiar with. Ironically, this next part is gonna be the one that gives you a headache. Tone shift.
