When placing orders on MT5 for the first time, many users notice a volume input box. This field is not for entering monetary amounts; instead, it is for trading lot sizes. Values such as 0.01, 0.1 and 1.00 represent different trading scales, so you need to understand their differences before submitting orders.

1. Where to Enter Trading Volume in MT5

After opening the MT5 order window, locate the Volume field.

On MT5 mobile, you may adjust volume via the adjustment buttons beside the field or input figures directly. Volume is measured in lots.

For example, entering 0.01 means trading 0.01 lot. Entering 0.10 means 0.1 lot. Entering 1.00 means 1 lot.

2. Minimum Lot Size for Gold on Lucky Gold

For London Gold on Lucky Gold, the minimum trading volume is 0.01 lot, and the maximum per-order size is 10 lots. One standard lot equals 100 troy ounces.

The corresponding conversion is as follows: - 0.01 lot ≈ 1 troy ounce - 0.1 lot ≈ 10 troy ounces - 1 lot = 100 troy ounces

Given identical market price movements, different lot sizes will produce markedly different changes to your account balance.

3. Why You Should Not Input Monetary Amounts in the Volume Field

Volume in MT5 denotes lot size, not the amount of US dollars you intend to invest.

For instance, entering “1” in the volume box does not mean trading 1 US dollar; it represents one standard lot.

This point is critical. If you intended to trade 0.01 lot but mistakenly entered 1.00, your actual trading exposure will be 100 times larger. Always double-check the decimal point position before clicking submit.

4. Profit-and-Loss Difference Between 0.01 Lot and 1 Lot for Given Price Moves

On Lucky Gold, one lot of London Gold equals 100 troy ounces, while 0.01 lot equals approximately 1 troy ounce.

Assume London Gold moves by 1 US dollar: - 1 lot generates approximately $100 profit or loss - 0.1 lot generates approximately $10 profit or loss - 0.01 lot generates approximately $1 profit or loss

Setting your trading volume essentially determines how much your account fluctuates for each unit of price movement.

5. What to Do If You Enter the Wrong Volume

If you have not yet submitted the order, simply edit the volume value.

If the order has already been created, follow procedures according to its current status.

For pending orders, the MT5 pending-order modification window generally does not allow direct changes to preset trade volume. To adjust lot size, delete the original pending order and create a new one with the corrected volume.

Verifying volume before placing an order is far more convenient than making adjustments after submission.

6. Practical Applications of Small Lot Sizes

Lucky Gold supports a minimum of 0.01 lot, allowing users to subdivide trading scale according to their own plans. The platform also provides a mobile APP synchronised with MT5 data for convenient checking of order lot sizes and account changes.

For traders who are new to the software, focus first on correctly entering volume, reviewing orders and familiarising yourself with operational workflows.
