How to Set Your Default Lot Size in MetaTrader 5 (MT5)

Setting a default lot size in MetaTrader 5 saves time and ensures consistency when placing trades—especially if you frequently use the same position size. Here’s how to configure it on both desktop and mobile.

Step 1: Open MetaTrader 5

Launch the MT5 platform on your desktop or mobile device.

Step 2: Enable One-Click Trading (Required)

Before setting a default lot size, ensure One-Click Trading is enabled.

• Go to Tools → Options → Trade tab.

• Check One-Click Trading and click OK.

Step 3: Set Default Lot Size on Desktop

• Open a chart and locate the One-Click Trading panel in the top-left corner.

• Enter your desired lot size in the field next to the Buy and Sell buttons.

• MT5 will remember this amount for future trades on that instrument.

Step 4: Set Default Lot Size on Mobile

• Tap the Quotes or Chart screen.

• When you open the trade window, input your preferred lot size before placing an order.

• MT5 will store your last used lot size for your next trade.

Tips for Setting Lot Size

• Always choose a size based on your risk management plan.

• Adjust for volatility—larger positions increase exposure.
