Kill Switch
A feature that allows users to quickly stop trading or halt automated trading algorithms in the event of significant market movements or technical failures.

What Is Kill Switch (in Trading)?
Kill Switch in trading is a safety mechanism that lets traders or platforms instantly halt all trading activities, usually to prevent or minimize losses in case of high volatility or technical issues. Think of it as a big red "stop" button that, when pressed, can shut down trading to avoid further risk.
How It Works
- Manual or Automated Activation: A kill switch can be triggered manually by a trader or automatically by an algorithm if certain conditions, like extreme price drops or rapid changes, are met.
- Immediate Effect: When the kill switch is activated, it stops all trades and may also cancel pending orders, helping prevent further losses.
- Risk Management: Often used by both traders and exchanges, the kill switch helps manage risk, especially in fast-moving markets.
Example:
Imagine a trader who’s running an algorithm that buys and sells stocks. If the market suddenly crashes, the trader can activate the kill switch to stop all trades, protecting against deeper losses.
Key Takeaways
- Kill Switch is a feature to stop all trading activity instantly, often used as a safety measure during market crashes or technical glitches.
- It can be manually triggered or set to go off automatically based on certain criteria.
- It’s an important risk management tool for both individual traders and trading platforms.
In short, a kill switch is like an emergency brake for your trading account—if things get wild, you can pull it to stop everything in its tracks!
