ml4t-kill-switch skillA
ml4t-kill-switch is agent-read markdown (skill) from ml4t/skills: Automated risk limits that halt trading when thresholds are breached. Use when deploying live strategies that need drawdown or loss-limit protection..
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
# Kill Switch
A human monitoring a dashboard will not react fast enough to a flash crash. By the time you see the loss and decide to act, the drawdown has compounded. Automated kill switches are the last line of defense - they must be hard-coded, not ML-based, and not overridable without explicit manual intervention.
## The Problem
Live trading systems face risks that backtests never encounter: data feed failures, exchange outages, runaway algorithms, and flash crashes. A strategy producing 100 orders per second during a data glitch can lose more in minutes than it earned in months. Manual monitoring fails because: (1) humans are slow, (2) losses compound nonlinearly, and (3) the worst events happen when attention is lowest. Kill switches must trigger automatically, flatten positions immediately, and require human approval to resume.
## The Pattern
### WRONG
```python
# "I'll watch the dashboard and close positions if things go wrong"
import time
while True:
pnl = get_daily_pnl()
if pnl < -10000:
send_email("Loss alert") # arrives 5 min later, read at 9am
time.sleep(60)
# Meanwhile, the algo keeps trading during the 60s sleep
```
### CORRECT
```python

How to install
mdr add ml4t/skills/ml4t-kill-switch@git:20260901.830d7a8mdr add ml4t/skills/ml4t-kill-switch@sha256:c32c27240f5e2d21Pin 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.
