One Large Order or Several Small Ones? Comparing Trading Approaches

When choosing between one large order or several small orders in trading, it is important to consider various factors, as each approach has its own advantages and disadvantages.

One large order

Advantages:

• Ease of execution: It is easier to manage one order than several.

• Lower commissions (potentially): Some brokers may charge a fixed commission per order, so one large order might be cheaper than several small ones.

• Speed of execution: If there is sufficient liquidity, a large order can be executed faster as there is no need to wait for the execution of several parts.

Disadvantages:

• Market impact: A large order can significantly affect the price of an asset, especially in low-liquidity markets. This can lead to unfavorable execution (slippage).

• Risk: If the order is executed at an unfavorable price, the losses can be substantial.

• Less flexibility: It is more difficult to adapt to changing market conditions after placing a large order.

Several small orders

Advantages:

• Reduced market impact: Breaking down a large order into smaller parts helps avoid significant price impact, especially when using limit orders.

• Flexibility: Allows adaptation to market conditions. If the price moves unfavorably, subsequent parts of the order can be paused or modified.

• Price averaging: Enables averaging the entry or exit price, reducing the risk associated with a single entry/exit point. This is especially useful for gradual position building strategies (DCA - Dollar-Cost Averaging).

• Reduced slippage risk: Smaller orders are generally easier to execute at the desired price.

Disadvantages:

• Higher commissions (potentially): If the broker charges a commission for each order, several small orders may be more expensive.

• Management complexity: Managing multiple orders can be more complex and require more time and attention.

• Execution time: Executing the entire position may take longer, as each part needs to be waited for.

When to use what?

• A single large order may be advisable for:

  • Highly liquid markets with large trading volumes.

  • Quick trades where time is critical.

  • Traders who are confident in their entry/exit points and do not expect significant slippage.

• Several small orders are better suited for:

  • Markets with low liquidity or exotic assets.

  • Strategies involving gradual entry or exit from a position (e.g., averaging).

  • Reducing slippage risk and market impact.

  • Traders seeking greater flexibility and control over their trade execution.

Conclusion

The choice between one large order and several small ones depends on your trading strategy, asset liquidity, position size, risk tolerance, and broker commissions. For most traders, especially those dealing with large sums or in less liquid markets, breaking down an order into several smaller parts is often a safer and more effective approach, allowing for better execution control and risk minimization.
