Limit Order

A limit order is the most basic type of order, where a user places a buy or sell instruction at a specified price.

• A buy limit order requires purchasing the asset at a price no higher than the set level.

• A sell limit order requires selling the asset at a price no lower than the set level. The main purpose is to give traders precise control over the execution price. However, such orders are not executed immediately—they will only be filled once the market price reaches the specified condition. Limit orders are useful when the target entry or exit price is clear, and the trader is willing to wait until the market meets that condition.

Take Profit & Stop Loss

Building on this, take profit (TP) and stop loss (SL) are extensions of the limit order function, designed to help traders lock in profits or limit losses when they cannot monitor the market in real time. A TP/SL order is executed by presetting a trigger price, order price, and quantity. When the market reaches the trigger price, the system automatically places a limit order at the predefined price and amount.

• Take Profit (TP): used to secure gains when the price rises to a target level.

• Stop Loss (SL): used to minimize losses when the price falls to a preset threshold. This is especially useful to avoid emotional trading and reduce risk. Example: When Bitcoin is priced at 19,000 USDT, a trader may set a TP trigger at 20,000 USDT and an SL trigger at 18,000 USDT. Once the market hits 20,000 or 18,000, the system automatically places a limit order at the preset order price. The order price can be slightly higher or lower than the trigger price to improve execution probability. For instance, if 1 BTC is bought at 20,000 USDT, and the trader wants to take profit at +10%, the TP trigger can be set at 21,000 USDT with an order price of 22,000 USDT. Once 21,000 is reached, the order activates; if the price continues upward to 22,000 or beyond, the system automatically sells. Stop loss works in a similar way.

Trigger Price Types

When setting TP/SL, traders must choose the reference for the trigger price:

• Last Price: the most recent traded price. It reacts quickly and is suitable for short-term trading but is vulnerable to volatility and slippage in illiquid markets.

• Mark Price: derived from the index price and funding rates. It is more stable and prevents abnormal triggers caused by manipulation or low liquidity, making it better for mid- to long-term positions, though slower to react in volatile conditions. From an execution perspective, a limit order has only one condition (the order price), and executes once the market reaches or betters that price. A TP/SL limit order adds a trigger price—the order only enters the market after being triggered. Thus, limit orders mainly control price, while TP/SL limit orders add automated risk management and profit protection.

Trailing Stop

In addition to regular TP/SL, there is also the trailing stop order. A trailing stop dynamically adjusts the trigger price as the market moves in a favorable direction, thereby locking in more profit while still exiting automatically if the price retraces by a set percentage. Example: If the trailing distance is set at 5%, and the buy price is 200 USDT, when the market rises to 210 USDT, the trigger price shifts upward to 199.5 USDT. If the price then falls back to this level, the system executes a market sell, securing part of the gain while limiting potential loss.

Advantages of TP/SL Limit Orders

• Provide traders with autonomy and planning flexibility.

• For 24/7 crypto markets, they allow automatic execution without constant monitoring, preventing missed opportunities.

• Enable traders to predefine profit targets and risk ranges, ensuring execution at planned levels rather than arbitrary market prices.

• Particularly suitable for long-term holders who want to protect profitability without compromising on execution price.

Disadvantages of TP/SL Limit Orders

• Same limitation as limit orders: execution is not guaranteed. The order only fills if the market reaches the order price, which may never occur.

• Even with a gap between trigger and order price, the difference might be too small, causing missed trades.

• In volatile markets, prices may jump past the preset range.

• Liquidity can also be an issue—orders may only be partially filled if counterparties are lacking. Traders may consider using Fill or Kill (FOK) orders to ensure full execution, though the more conditions added, the lower the probability of execution.

Strategies for Using TP/SL

Limit Orders To maximize effectiveness, strategies should be adapted to the asset and market environment:

1. Assess volatility: For highly volatile assets, allow more distance between trigger and order prices to increase execution chances.

2. Consider liquidity: In illiquid markets with wide spreads, these orders help avoid unfavorable fills due to slippage.

3. Apply technical analysis: Place TP/SL levels around support and resistance.
