STOP ORDER
Back to GlossaryDefinition
An order activated when a stop price is reached, used to limit losses or enter positions on breakouts.
Summary
A stop order is a conditional trading instruction that becomes a market order once a specified price (the stop price) is reached. Think of it as a safety mechanism that automatically triggers action when the stock price moves to a predetermined level. There are two main types: stop-loss orders (used to limit losses on existing positions) and stop orders for entry (used to enter positions when price breaks through resistance or support levels). The key feature is that the order 'sleeps' until the trigger price is hit, then it 'wakes up' and executes as a regular market order.
Usage Context
Essential when learning about risk management strategies, order types, trading mechanics, and portfolio protection techniques. Critical for understanding how traders and investors protect themselves from significant losses and automate entry/exit decisions.
Common Confusions
- Thinking stop orders guarantee execution at the exact stop price (they don't - they become market orders)
- Confusing stop orders with stop-limit orders (different execution methods)
- Not understanding that stop orders can trigger on temporary price spikes
- Believing stop orders provide complete protection against all losses
- Mixing up buy stop orders (placed above current price) with sell stop orders (placed below current price)
