mftik

The strategy SDK and command-line client for a MFTIK node — a self-hosted, mid-frequency algorithmic trading platform.

You run the node yourself with Docker Compose — mftik node-init writes the stack for you. This package is both that and what you install on the machine you write strategies on.

pip install mftik

Writing a strategy

A strategy is a subclass of Strategy and a directory of .py files. It reads market data through the hooks it overrides and trades through the accessors the base class binds.

from mftik.strategy import Strategy


class MyStrategy(Strategy):
    name = "my_strategy"

    async def on_best_quote(self, quote) -> None:
        await self.log(f"{quote.universal_ticker} {quote.bid}/{quote.ask}")

self.oms places and cancels orders, self.ledger reads balances, self.mds queries history the feeds do not carry, self.tape warms up on prints from before the session started, self.symbols gives you the tick and step sizes to round to, and self.timer schedules work. See Strategy's docstring for the full set of hooks.

A strategy may import the standard library, mftik, and other files in its own directory — nothing else. The node runs the source you send it rather than an environment you built, so a third-party import would be a module that is not there. mftik check tells you before you push.

The client

mftik node-init ./mynode                 # a whole node: compose, edge, .env
mftik connect https://node.example.com   # sign in once; stores an API key
mftik whoami                             # who you are to that node
mftik profiles                           # every node this machine knows
mftik disconnect <name>                  # forget one
mftik init ./hello                       # scaffold, filled in from that node
mftik check ./hello                      # import gate and on_initialized, offline
mftik run ./hello                        # push, deploy, tail; ^C stops it
mftik push ./hello                       # copy the tree into the node's private registry
mftik run ./hello                        # push, deploy, tail the session log
mftik ps                                 # what is running
mftik logs -f <session>                  # what it is saying
mftik stop <session>                     # stop it

connect signs in with your password, mints an API key through that session, stores the key and drops the session — so the password is never written down. Profiles live in ~/.config/mftik/config.toml at mode 0600. For CI, pass an existing key with --token and no prompt is reached.

init is being built — see docs/CLI.md for the shape it is landing in.
