ml4t-live-trading skillA
ml4t-live-trading is agent-read markdown (skill) from ml4t/skills: Transition from backtest to live trading with zero code changes. Use when deploying a validated strategy to paper or live trading via broker APIs..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260901.85fc79bmdr add ml4t/skills/ml4t-live-trading@sha256:3002c9e293b9f028Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
