Transition from backtest to live trading with zero code changes. Use when deploying a validated strategy to paper or live trading via broker APIs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Backtest-to-Live Deployment
Rewriting strategy logic for live trading introduces bugs and invalidates your backtest. The correct pattern is to reuse the exact Strategy class from backtesting - zero code changes between simulation and production.
## The Problem
Teams often validate a strategy in backtest, then rewrite it for live trading.
That rewrite changes rounding, timing, or position tracking and silently breaks
the link to the validated backtest.
## The Pattern
### WRONG
```python
# Separate live strategy - rewrites logic, diverges from backtest
class LiveMomentumTrader:
def __init__(self, api_key):
self.api = BrokerAPI(api_key)
def run(self):
while True:
prices = self.api.get_latest_bars(100)
signal = prices["close"].pct_change(20).iloc[-1]
if signal > 0:
self.api.market_buy("SPY", 100) # Different sizing logic
elif signal < 0:
self.api.market_sell("SPY", 100) # No cost model
time.sleep(60)
```
### CORRECT
```python
from abc import ABC, abstractmethod
class Strategy(ABC):
"""Single strategy class used for BOTH backtest and live."""

How to install
mdr add ml4t/skills/ml4t-live-trading@sha256:3002c9e293b9f028The line at the top of this page pins the label git:20260901.85fc79b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
