Stop Limit Order
Stop Limit Order
A two-stage order combining stop and limit order characteristics. When the stop price is reached, the order becomes a limit order (not a market order) at the specified limit price. Provides price protection but risks non-execution if the market price moves through the limit price before the order fills. Requires two prices: the stop price (trigger) and the limit price (execution boundary).
An investor owns shares of XYZ stock trading at $50 and wants downside protection but also wants control over the sale price. She enters a sell stop-limit order with a stop price of $45 and a limit price of $44. If XYZ falls to $45, the order is triggered and becomes a limit order to sell at $44 or better. If the price quickly drops from $45 to $42, the order will NOT execute (since $42 is below the $44 limit), protecting the investor from selling at the worst prices but leaving her still holding shares that have fallen below $44.
Students often confuse stop-limit orders with regular stop orders. A stop order becomes a market order when triggered (guarantees execution but not price), while a stop-limit becomes a limit order (guarantees price or better but not execution). Another common mistake is not understanding that stop-limit orders can fail to execute entirely in fast-moving markets. Many also confuse which price is the trigger (stop price) versus which is the execution boundary (limit price), or fail to recognize that for sell orders, the limit price is typically below the stop price.
How This Is Tested
- Distinguishing between stop orders (market execution) and stop-limit orders (limit execution)
- Determining appropriate stop and limit price placement based on client objectives
- Identifying scenarios where stop-limit orders fail to execute due to price gaps
- Comparing execution certainty (stop order) versus price certainty (stop-limit order)
- Evaluating suitability of stop-limit orders for clients needing guaranteed execution versus price protection
Regulatory Limits
| Description | Limit | Notes |
|---|---|---|
| Stop price relationship to current market | Below current price for sell orders, above for buy orders | Stop price acts as trigger point when market reaches it |
| Limit price relationship to stop price | Sell: limit typically at or below stop; Buy: limit typically at or above stop | Defines acceptable execution price range after trigger |
Example Exam Questions
Test your understanding with these practice questions. Select an answer to see the explanation.
Maria owns 1,000 shares of ABC stock currently trading at $62 per share. She wants to protect against significant downside but is concerned about selling at an unacceptably low price during a sudden market drop. She prefers not to sell below $58 under any circumstances, even if it means potentially not selling at all. Which order type is most appropriate for Maria?
C is correct. A sell stop-limit order with a stop at $60 and limit at $58 best meets Maria's needs. When ABC falls to $60, the order triggers and becomes a limit order to sell at $58 or better, ensuring she won't sell below her $58 floor. This provides the downside protection she wants while respecting her price requirement. However, Maria should understand that if the price gaps down from $60 to below $58 (e.g., drops to $55 suddenly), the order will not execute and she'll still hold shares that have fallen below her acceptable price.
A (sell stop order at $60) would trigger at $60 but become a market order, potentially executing at any price below $60, including well below her $58 minimum (perhaps at $55 or lower in a fast market). This doesn't provide the price protection she requires. B (sell limit order at $58) would only execute at $58 or better, but provides no downside protection if the stock never reaches $58. If ABC falls from $62 to $50 without touching $58, the limit order never executes. D (market order) would sell immediately at the current market price (~$62) with no downside protection, not meeting her objective of protecting against future declines.
The Series 65 exam tests your ability to match order types to specific client needs. Stop-limit orders are appropriate when clients want both downside protection (stop feature) and price control (limit feature), but you must explain the tradeoff: potential non-execution in volatile markets. Understanding this balance between execution certainty and price certainty is critical for suitability.
What happens when a stop-limit order is triggered (reaches the stop price)?
B is correct. When a stop-limit order reaches the stop price (trigger point), it becomes a limit order at the specified limit price. This means the order will only execute at the limit price or better, providing price protection but no guarantee of execution. The order remains active as a limit order until it executes, expires, or is canceled.
A describes what happens with a regular stop order (not stop-limit), which becomes a market order upon trigger and executes at the best available price. This is the key difference between stop orders and stop-limit orders. C is incorrect because stop-limit orders do not automatically cancel when triggered; they become active limit orders awaiting execution at the limit price or better. D incorrectly describes a stop order with day duration, not a stop-limit order. Stop-limit orders become limit orders (not market orders) and can have various time-in-force instructions (day, GTC, etc.).
The Series 65 exam frequently tests the mechanical difference between stop orders and stop-limit orders. You must understand that stop-limit orders provide a two-stage process: first the stop price triggers the order, then the limit price controls execution. This two-stage mechanism is the defining characteristic that distinguishes stop-limit orders from regular stop orders.

Access Free BetaAn investor places a sell stop-limit order for DEF stock with a stop price of $72 and a limit price of $70. DEF is currently trading at $75. The stock subsequently trades at the following prices in sequence: $74, $73, $71.50, $69, $70.50. At what price, if any, does the investor's order execute?
C is correct. The order executes at $71.50. Here's the sequence: DEF falls from $75 to $74, then $73. When it reaches $72 (the stop price), the stop-limit order is triggered and becomes a limit order to sell at $70 or better. The next trade in the sequence is $71.50. Since this is a SELL limit order at $70, "or better" means $70 or HIGHER (better for the seller). $71.50 is above $70, so the order executes at $71.50, achieving a better price than the $70 minimum the investor specified.
A is incorrect because the order does not execute immediately at $72. At $72, the order only triggers and becomes a limit order; execution depends on finding a buyer at $70 or better. B is incorrect because the order would have already executed at $71.50 before the price fell to $69 and rebounded to $70.50. Once executed, the order is filled and no longer active. D is incorrect because $71.50 is an acceptable execution price (at or above the $70 limit for a sell order), so the order does execute.
The Series 65 exam tests your ability to trace order execution through price movements. You must understand that stop-limit orders have two distinct stages: trigger (when stop price is reached) and execution (when limit price or better is available). For sell orders, "better" means higher prices. Understanding this two-stage process and the meaning of "or better" for different order sides is critical for analyzing whether and when orders execute.
All of the following statements about stop-limit orders are accurate EXCEPT
B is correct (the EXCEPT answer). This statement is FALSE. Once triggered, a stop-limit order becomes a LIMIT order (not a market order), which does NOT guarantee execution. The order will only execute at the limit price or better, and if the market moves past the limit price, the order may never fill. This execution uncertainty is the key tradeoff of using stop-limit orders instead of regular stop orders.
A is accurate: stop-limit orders require both a stop price (trigger point) and a limit price (execution boundary), distinguishing them from regular stop orders that only need a stop price. C is accurate: this describes the primary risk of stop-limit orders. In fast-moving or gapping markets, the price can move from above the stop price to below the limit price (for sell orders) without any execution occurring, leaving the investor unprotected. D is accurate: this correctly describes the fundamental tradeoff. Stop-limit orders give you control over execution price (won't sell below your limit) but sacrifice execution certainty (might not sell at all). Regular stop orders guarantee execution (become market orders) but sacrifice price control (might execute at any price).
The Series 65 exam tests your understanding of order type tradeoffs and risk characteristics. The most critical concept for stop-limit orders is that they do NOT guarantee execution, unlike stop orders. This execution risk must be disclosed to clients who choose stop-limit orders for downside protection, as they may end up with no protection if the order never fills during a sharp market decline.
A client places a sell stop-limit order for GHI stock with a stop price of $48 and a limit price of $46. GHI is currently at $52. Which of the following statements are accurate?
1. The order will trigger if GHI trades at or below $48
2. Once triggered, the order will only execute at $46 or higher
3. This order provides guaranteed downside protection at $46
4. This order is more likely to execute than a sell stop order at $48 in a rapidly declining market
A is correct. Only statements 1 and 2 are accurate.
Statement 1 is TRUE: The order triggers when GHI trades at or below the stop price of $48. Once the stock hits $48, the stop-limit order activates and becomes a limit order.
Statement 2 is TRUE: After triggering, the order becomes a limit order to sell at $46 or better (higher). For a sell limit order, "or better" means at the limit price or any price above it. The order will only execute at $46 or higher, providing price protection against selling below $46.
Statement 3 is FALSE: The order does NOT provide guaranteed downside protection. While it prevents selling below $46, it does not guarantee execution. If GHI gaps down from $48 to $44 (below the $46 limit), the order will never execute and the client still holds shares that have fallen below $46. Guaranteed protection would require a regular stop order, which guarantees execution but not price.
Statement 4 is FALSE: A stop-limit order is LESS likely to execute than a regular stop order in rapidly declining markets. A sell stop order at $48 becomes a market order upon trigger, guaranteeing execution (though possibly at prices below $48). The stop-limit order will only execute at $46 or better, which may not be available if the market is falling rapidly. This is the key tradeoff: stop-limit orders sacrifice execution certainty for price control.
The Series 65 exam tests your comprehensive understanding of stop-limit order mechanics, including trigger conditions, execution requirements, and the critical distinction between price protection (what the order provides) and downside protection (what it does NOT guarantee). You must understand that stop-limit orders can fail to execute entirely, leaving clients unprotected despite having placed the order. This execution risk is the primary suitability consideration when recommending stop-limit orders versus regular stop orders.
💡 Memory Aid
Stop-Limit = Two-Stage Safety: First, the stop price TRIGGERS the order (like an alarm going off). Then, the limit price CONTROLS execution (sets your acceptable price range). Think of it as "trigger then bargain": the stop says WHEN to start trying to sell, the limit says "only at this price or better." Risk: In a crash, you might trigger but never execute (price gaps through your limit), leaving you unprotected. Stop-Limit = price control but no execution guarantee.
