Choosing the Right Order

Quick trade, no concern for price: Market order.

Control over price, willing to wait: Limit order.

Protect against loss: Stop order or stop-limit order.

Protect profits as price moves in your favor: Trailing stop.

Don’t want partial fills: Fill-or5. Trailing Stop Order

What it is: A trailing stop is a type of stop order that moves with the market price. It’s set at a percentage or dollar amount away from the highest price reached after the order is placed.

When to use it: Use it when you want to lock in profits as the market moves in your favor, while still protecting against downside risk.

Pros:

Automatically adjusts as the market price moves in your favor.

It may get triggered too early in volatile conditions.

6. Fill or Kill (FOK)

When to use it: When you want to get in or out of a position in one go, without partial fills.

Pros:

Guarantees either a full fill or no fill at all.

Cons:

The order might not be filled at all if the market conditions don’t meet the requirements.

7. Good ‘Til Canceled (GTC)

What it is: A GTC order remains active until it is either executed or canceled by the trader, which could be days, weeks, or even longer.

When to use it: Use this if you want to set a price and forget about it until the order is filled or canceled.

Pros:

Convenience—doesn’t need to be renewed everyday
