Note: Due to high number of requests I am in the process of writing some mathemagical notes which seek to explain what is going on here and what kind of models the solvers are supposed to represent. Sit tight!

HFT

This repository contains semi random collection of "High Frequency Market Making" algorithms created using stochastic optimal control. Resulting Dynamic Programming Equations are solved using simple Euler finite difference scheme.
