The order type you choose determines the price you pay, execution speed, and how much control you have.
A says: "Buy/sell right now at whatever price is available."
Use when speed matters more than price: urgent exits or liquid stocks with tight spreads. On AAPL.US with a 1-cent spread, is negligible. On a thinly traded stock with a 10-cent spread, you could pay much more than expected.
Slippage Alert
Never use market orders on stocks with spreads wider than 0.1% of share price. Also avoid them during the first 5 minutes after the open.
A says: "Buy/sell only at this price or better." If the stock never reaches your price, nothing happens.
This is the swing trader's best friend. Plan trades after hours, set your exact entry price, walk away. The market does the work.
A sits dormant until the trigger price is hit.
Gap risk: If a stock gaps past your stop overnight ($44 instead of $47), your stop triggers at $44. This is a trade-off swing traders accept.
A places your profit target and stop-loss simultaneously. When one fills, the other cancels.
Example: Buy 100 shares at $50. Set sell limit at $58 (target) and sell stop at $47 (stop-loss). Whichever hits first executes, the other cancels. True "set and forget."
Stop-Loss Placement
Do not place stops too tight. If your stop is within the stock's normal daily range (ATR), you will get stopped out by noise, not a genuine reversal. Place stops at least 1.5x ATR away or below a clear technical level.
Key Takeaways
Try This
In your paper trading account, place a bracket order: pick a watchlist stock, set a limit entry at nearby support, add a stop-loss below the next support, and a target near resistance. Watch how it behaves over the next few days.
