'Lot size' is the expression of the number of trading contracts. It is not an abstract decimal, it corresponds to a specific amount of gold or silver behind it.Wmax · 威马证券 is currentlyLondon Gold1 lot corresponds to 100 ounces, and 1 lot of London silver corresponds to 5000 ounces, with a minimum trading volume of 0.01 lots for both.

How to exchange London gold lots

Calculated at 100 ounces per hand:

0.01 hand corresponds to 1 ounce; 0.1 hand corresponds to 10 ounces; 0.5 hands correspond to 50 ounces; One hand corresponds to 100 ounces.

So 0.01 and 0.1 appear to be only one decimal place apart, but the actual contract size differs by 10 times.

The feeling that London silver cannot simply copy gold

One lot of London silver corresponds to 5000 ounces.

0.01 lot is 50 ounces, 0.1 lot is 500 ounces, and 1 lot is 5000 ounces.

That's also why the price exposure of gold and silver is completely different when both are written as "0.1 lots". When changing trading varieties, first look at the contract unit and then decide on the number of lots.

What will the number of hands affect simultaneously

After the number of lots increases, the margin occupancy, profit and loss corresponding to price fluctuations, spread costs, and possible overnight fees will all increase accordingly.

For example, for every $1 change in the price of 1 lot of London gold, the theoretical floating amount is about $100; 0.1 lot is about 10 US dollars; 0.01 lots is about 1 dollar.

A minimum of 0.01 hands is not suitable for everyone

The minimum trading volume allowed by the system only indicates the technical order range. The actual amount to be done depends on the account funds, planned stop loss distance, and acceptable loss amount.

Some users only push their hand count backwards based on margin, resulting in a position that can be opened just in time, but without leaving a buffer for normal price fluctuations. This approach appears to have a high utilization rate, but in reality, the account will become very tight.

Perform a simple check before placing an order

Confirm the trading variety, then confirm the lot size, and replace the lot size with the corresponding ounce quantity. Finally, ask yourself: How much will this position change if the price moves in an unfavorable direction by $1 or $0.1?

By turning this step into a habit, many problems such as incorrect lot numbers and excessive positions can be detected in advance.

Replacing the hand count with 'how many ounces corresponds to' makes it easier to understand

1 lot of London gold corresponds to 100 ounces, so 0.01 lot corresponds to 1 ounce, 0.1 lot corresponds to 10 ounces, and 0.5 lot corresponds to 50 ounces. 1 lot of London silver corresponds to 5000 ounces, and 0.01 lot corresponds to 50 ounces. It looks like they are all 0.01 lots, with significant differences in the number of contracts behind them.

That's also why when switching from gold to silver, the original hand count cannot be used. 0.1 lot of gold corresponds to 10 ounces, while 0.1 lot of silver corresponds to 500 ounces. The price fluctuations and contract units of different products are different, and the number of lots is only a standardized ordering unit. The true determinant of account changes is "lots x contract units x price changes".

Lot size and margin are not the same thing

The number of lots represents the size of the position, and the margin represents how much account funds are required to establish this position.Wmax · 威马证券 currently has a London gold margin of $1000 per lot and a London silver margin of $650 per lot. Taking gold as an example, 0.1 lots occupy approximately $100 of margin at the current standard; But 0.1 lots correspond to 10 ounces, and for every $1 change in gold price, the theoretical floating amount is about $10.

So just because the margin is only $100, we cannot understand this $100 as the maximum loss that an order will incur. If the market continues to operate in an unfavorable direction, the floating losses will continue to change, and the account must also meet the corresponding prepayment ratio requirements.

Why is 0.01 hand often misunderstood by beginners

The minimum support is 0.01 lots, which expresses the minimum order unit allowed by the system. It is not equivalent to 'everyone is suitable to start from 0.01', nor is it equivalent to 'just preparing the corresponding margin is enough'. Whether an account can withstand a certain lot size depends on its net asset value, stop loss distance, planned holding time, and the maximum loss it is willing to bear.

For example, 0.01 lot of gold corresponds to 1 ounce. If the planned stop loss distance is $20 and other fees are ignored, the theoretical price risk is about $20; If the stop loss distance expands to $50, the risk also becomes about $50. Both are 0.01 lots, and the actual volatility experienced varies depending on the trading plan.

How to avoid inputting the wrong number of lots when placing an order

The difference between 0.01, 0.1, and 1.0 on the mobile interface is only one decimal point, but the impact on the amount varies by 10 or even 100 times. It is best to review the product name, direction, and number of lots again before submitting an order, especially when switching from a demo account to a live market or from gold to silver.

We suggest recording the number of commonly used lots and corresponding contract quantities. When you see 0.1 hands in this way, your mind will naturally associate them with "10 ounces of gold" or "500 ounces of silver", which is less likely to make mistakes than just memorizing a decimal.

Risk Warning: Margin trading can amplify the impact of price changes on the account. The number of lots should be arranged based on the account's net asset value, available funds, and risk tolerance.

确认交易品种，再确认手数，然后把手数换成对应盎司数量。最后问自己一句：如果价格向不利方向走1美元或0.1美元，这个仓位会变化多少钱？

把这一步变成习惯，很多手数输错、仓位过大的问题都能提前发现。

手数先换成“对应多少盎司”更容易理解

伦敦金1手对应100盎司，所以0.01手对应1盎司，0.1手对应10盎司，0.5手对应50盎司。伦敦银1手对应5000盎司，0.01手则对应50盎司。看上去都是0.01手，背后的合约数量差异很大。

这也是为什么从黄金切换到白银时，不能沿用原来的手数感觉。黄金0.1手对应10盎司，白银0.1手却对应500盎司。不同产品的价格波动幅度和合约单位都不同，手数只是一种标准化下单单位，真正决定账户变化的是“手数×合约单位×价格变化”。

手数和保证金不是一回事

手数表示仓位规模，保证金表示建立这个仓位需要占用多少账户资金。Wmax · 威马证券当前伦敦金保证金为1000美元/手、伦敦银为650美元/手。以黄金为例，0.1手按当前标准约占用100美元保证金；但0.1手对应10盎司，金价每变化1美元，理论浮动金额约10美元。

所以不能因为保证金只占用100美元，就把这100美元理解成订单最多会产生的亏损。市场如果连续向不利方向运行，浮亏会持续变化，账户还要满足相应的预付款比例要求。

0.01手为什么经常被新手误解

最低支持0.01手，表达的是系统允许的最小下单单位。它并不等同于“所有人都适合从0.01手开始”，也不等同于“只准备对应保证金就够了”。一个账户能否承受某个手数，还要看账户净值、止损距离、计划持仓时间以及自己愿意承担的最大亏损。

举个简单例子：黄金0.01手对应1盎司。如果计划止损距离是20美元，忽略其他费用时，理论价格风险约20美元；如果止损距离扩大到50美元，风险也随之变成约50美元。同样都是0.01手，交易计划不同，实际承受的波动并不一样。

下单时怎么避免输错手数

手机界面里的0.01、0.1、1.0只差一个小数点，金额影响却相差10倍甚至100倍。提交订单前最好再看一次产品名称、方向和手数，特别是从模拟账户切到实盘、从黄金切到白银时。

我们更建议把常用手数和对应合约数量记下来。这样看到0.1手时，脑子里会自然联想到“黄金10盎司”或“白银500盎司”，比只记一个小数更不容易出错。

风险提示：保证金交易会放大价格变化对账户的影响。手数应结合账户净值、可用资金和风险承受能力安排。
