FastMM

FastMM is a low-latency market-making engine for crypto exchanges. You write the quoting logic in Python or C++; FastMM runs it in backtests and live, quotes on one exchange and hedges on another, and recovers from crashes without losing track of a trade.

Quickstart

pip install "fastmm-engine[hot]"
fastmm init my-mm && cd my-mm
python backtest.py

This runs a strategy on a simulated market, with no account and no API keys (Linux x86-64, Python 3.10+).

A strategy

import fastmm
from fastmm import Param


class TouchMM(fastmm.Strategy):
    half_spread_bps = Param(0.01, min=0.0, doc="half spread, bps")
    quote_qty = Param(0.002, min=0.0, doc="size per side")

    @fastmm.hot  # compiled to machine code with Numba
    def on_book(self, ctx, book):
        if not book.valid:
            ctx.pull()
            return
        half = book.mid * self.half_spread_bps * 1e-4
        ctx.clear()
        ctx.bid(book.mid - half, self.quote_qty)
        ctx.ask(book.mid + half, self.quote_qty)
        ctx.keep_passive()
