Silver (XAG/USD) lot size and pip value: contract size, margin and position sizing

On many trading platforms, one standard lot of silver (XAG/USD) is 5,000 troy ounces, so every 0.001 dollar move in the silver price is worth 5 dollars per lot, every 0.01 move is worth 50 dollars, and a 1 dollar move is worth 5,000 dollars. A micro lot of 0.01 is 50 ounces, worth 0.50 dollars per cent and 50 dollars per dollar. Because contract sizes and pip definitions differ between providers, the reliable habit is to work in dollars per ounce and multiply by the number of ounces you actually hold.

That one-line answer hides several traps. Silver is quoted to three decimal places, the word "pip" means different things on different platforms, the margin rate under ESMA rules is double gold's, and silver moves further in percentage terms than gold does. This guide works through each piece with illustrative numbers, then sizes a trade in a dollar account and a euro account.

The XAG/USD quote

XAG is the ISO code for silver, in the same way XAU is gold. A quote of XAG/USD is the price of one troy ounce of silver (about 31.1 grams) in US dollars. Silver behaves like the base currency of a currency pair: if XAG/USD rises, silver has become more expensive in dollars.

Silver CFDs are typically quoted to three decimal places. Example only: a quote of 40.000 / 40.030 means you can sell at 40.000 dollars an ounce and buy at 40.030. The smallest price step on such a quote is 0.001 dollars, a tenth of a cent. The difference between the two prices, 0.030 dollars or three cents, is the spread.

Some platforms quote silver to two decimals, and some to four. The number of decimals tells you the minimum price step, not the value of a move; that depends on how many ounces you hold.

Contract size: what one lot of silver means

A lot is just a quantity. For currencies a standard lot is usually 100,000 units of the base currency; for silver it is a number of ounces, and that number is not standardised across the industry.

• 5,000 ounces is a common standard lot on MetaTrader platforms. It matches the size of the standard COMEX silver futures contract.
• 1,000 ounces is used by some providers, sometimes matching smaller futures contracts.
• 50 ounces or 100 ounces appear on some platforms that want a smaller minimum trade.
• 1 ounce per unit is common where positions are sized in ounces or units rather than lots.
• Cent and micro accounts may scale everything by 100 or 1,000, so that a "lot" on the platform is a small fraction of a standard lot elsewhere.

On MetaTrader you can find the contract size by right-clicking the symbol in Market Watch and opening its specification. Look for the contract size, the number of digits, the tick size and the minimum volume and volume step. The same information is usually on the broker's website under contract specifications. Do this before your first silver trade, and again if you change broker or account type, because the same symbol name can carry a different contract size on a different account. Our guide to broker account types explains how standard, raw, cent and micro accounts differ.

The rest of this guide assumes a 5,000-ounce standard lot, with lots tradable in steps of 0.01 (50 ounces). If your platform differs, swap in your own contract size; the method does not change.

Pips and points on silver: two conventions

On currency pairs a pip is clearly defined: 0.0001 for most pairs, 0.01 for yen pairs. On silver there is no such agreement.

• Pip = 0.001 dollars. Many CFD platforms and calculators, including ours, treat the smallest quoted step on a three-decimal silver price as one pip. On this convention, a move from 40.000 to 40.100 is 100 pips.
• Pip = 0.01 dollars. Others treat one cent as a pip and the 0.001 step as a pipette or point. On this convention, the same move from 40.000 to 40.100 is 10 pips.

So "my stop is 300 pips" means a 0.300 dollar stop to one trader and a 3.00 dollar stop to another, a tenfold difference. On MetaTrader, the stop and take-profit distance shown in "points" is always counted in the smallest price step, so on a three-decimal silver quote one point is 0.001.

The simplest way to avoid mistakes is to describe stops and moves in dollars per ounce: "a 0.45 dollar stop" means the same thing on every platform. You can convert to pips afterwards if a tool asks for them.

How many pips is 1 dollar on silver?

On the 0.001 convention, a 1 dollar move is 1,000 pips. On the 0.01 convention, it is 100 pips. For comparison, a 1 dollar move in gold is 100 points of 0.01, or 10 pips if your platform counts gold in 0.10 pips, which is why silver pip counts look so large next to gold. The gold CFD trading guide explains gold's conventions in the same way.

What each move is worth: pip value on silver

Pip value is the money value of one price step for a given position size. For a 5,000-ounce lot it is simply the price move multiplied by the number of ounces.

For one standard lot (5,000 ounces):

• A 0.001 dollar move is worth 5 dollars
• A 0.01 dollar move is worth 50 dollars
• A 0.10 dollar move is worth 500 dollars
• A 1 dollar move is worth 5,000 dollars

For a mini lot of 0.10 (500 ounces):

• A 0.001 dollar move is worth 0.50 dollars
• A 0.01 dollar move is worth 5 dollars
• A 1 dollar move is worth 500 dollars

For a micro lot of 0.01 (50 ounces):

• A 0.001 dollar move is worth 0.05 dollars
• A 0.01 dollar move is worth 0.50 dollars
• A 1 dollar move is worth 50 dollars

Because silver is priced in dollars, these values are fixed in dollars and do not depend on the silver price. If your account is in euros or pounds, the value in your own currency changes as the exchange rate moves.

Worked example: profit and loss on a silver trade

Example only. Silver is quoted at 40.000 / 40.030. You buy 0.05 lots (250 ounces) at 40.030.

1. The spread costs you 0.030 × 250 = 7.50 dollars the moment you open, because you could only sell back at 40.000.
2. Later the quote is 40.380 / 40.410 and you close by selling at 40.380.
3. Your result: (40.380 − 40.030) × 250 = 0.350 × 250 = 87.50 dollars, before any commission or overnight swap.

If instead silver had fallen and you sold at 39.680, the result would be (39.680 − 40.030) × 250 = −0.350 × 250 = −87.50 dollars. Same size, same distance, same money, in the other direction.

The profit and loss calculator runs this calculation for silver and other instruments, including the conversion into your account currency.

Margin on silver under ESMA's 10:1 cap

Under the ESMA product intervention rules that apply to retail clients of EU-regulated providers, CFDs on gold may be offered at up to 20:1 leverage, but silver falls into the "commodities other than gold" category, capped at 10:1. That means the minimum initial margin is 10% of the position's value. The UK FCA applies the same caps for retail clients. Providers can ask for more margin than the minimum but not less, and outside the EU and UK the limits may differ. Our guide to ESMA leverage limits and negative balance protection covers the whole framework.

The calculation:

• Margin = lots × ounces per lot × price × margin rate

Worked example: silver margin at 10:1

Example only. Silver is at 40.000 dollars an ounce and you hold a 5,000-ounce standard lot contract.

• 1.00 lot: 5,000 × 40.000 = 200,000 dollars of exposure; 10% margin = 20,000 dollars
• 0.10 lots: 500 × 40.000 = 20,000 dollars of exposure; margin = 2,000 dollars
• 0.01 lots: 50 × 40.000 = 2,000 dollars of exposure; margin = 200 dollars

In a euro account with EUR/USD at an illustrative 1.1000, the 2,000 dollars of margin for 0.10 lots is 2,000 ÷ 1.1000 = 1,818.18 euros.

Two points that catch people out. First, margin rises with the price: if silver were at 50 dollars, the same 0.10 lots would need 2,500 dollars. Second, margin is not your risk. A trader with 2,000 dollars in the account can open 0.10 lots, and a 1 dollar move against them, a move silver is capable of making within a single trading day, would cost 500 dollars, a quarter of the account. If losses push the margin level down to the close-out threshold (50% for EU retail clients), positions are closed automatically. Our guide to margin calls and stop-outs shows how that works.

The margin calculator for instruments includes silver with a 5,000-ounce default that you can overwrite.

Why silver is more volatile than gold

Silver shares many of gold's drivers, including the US dollar, real interest rates and demand for precious metals as a store of value. It differs in two ways that have historically made it more volatile.

• Industrial demand. A large share of silver demand comes from industry, including electronics and solar panels, which ties it more closely to the economic cycle than gold.
• A smaller market. The silver market is much smaller in value than the gold market, so the same flow of buying or selling tends to move the price further.

In practice that has meant larger daily ranges in percentage terms, sharper falls in sell-offs and sharper rallies in squeezes. Spreads on silver CFDs are usually wider than on gold relative to the price, and liquidity can thin out noticeably outside the main London and New York hours. If you are deciding when to trade the metals, our guide to the best time to trade gold explains the session pattern, which silver broadly shares; the LBMA Silver Price auction takes place at 12:00 London time.

Higher volatility is not a reason to trade silver or to avoid it. It is a reason to use wider stops in dollar terms, and therefore smaller positions, if you want the same money risk as on a calmer instrument.

Position sizing for silver

Position sizing turns "I am prepared to lose this much on this trade" into a number of lots. The method is the same as for currencies, explained in our position sizing guide. For silver in a dollar account:

• Lots = money at risk ÷ (stop distance in dollars per ounce × ounces per lot)

Always round the result down to your platform's volume step (usually 0.01 lots), never up.

Worked example: a dollar account

Example only. Your balance is 10,000 USD and you risk 1% per trade, so 100 USD. You plan to buy silver at 40.000 with a stop at 39.400, a stop distance of 0.600 dollars per ounce (600 pips on the 0.001 convention). One lot is 5,000 ounces.

1. Risk per standard lot: 0.600 × 5,000 = 3,000 USD
2. Lots: 100 ÷ 3,000 = 0.0333, rounded down to 0.03 lots (150 ounces)
3. Planned loss if the stop fills at its level: 150 × 0.600 = 90 USD
4. Margin at 10:1: 150 × 40.000 = 6,000 USD exposure, so 600 USD margin

Now allow for the spread. With a spread of 0.030, the effective distance from your buy price to the point where the stop triggers on the bid is about 0.630: 100 ÷ (0.630 × 5,000) = 0.0317, which still rounds down to 0.03 lots.

Notice that the rounding pulls the risk to 90 USD rather than 100. That is deliberate. Rounding up to 0.04 lots would put 200 ounces × 0.600 = 120 USD at risk, 20% more than planned.

Worked example: a euro account

Example only. Your balance is 5,000 EUR and you risk 1%, so 50 EUR. EUR/USD is at an illustrative 1.1000, so your risk in dollars is 50 × 1.1000 = 55 USD. You plan to sell silver at 40.000 with a stop at 40.450, a stop distance of 0.450 dollars per ounce.

1. Risk per standard lot: 0.450 × 5,000 = 2,250 USD
2. Lots: 55 ÷ 2,250 = 0.0244, rounded down to 0.02 lots (100 ounces)
3. Planned loss if the stop fills at its level: 100 × 0.450 = 45 USD, which is 45 ÷ 1.1000 = 40.91 EUR
4. Margin at 10:1: 100 × 40.000 = 4,000 USD exposure, so 400 USD margin, or 363.64 EUR

Because both the profit or loss and the margin are in dollars, the euro value of your open position also moves with EUR/USD. For a short silver position in a euro account, a stronger dollar adds a little to a gain and a little to a loss, measured in euros.

Worked example: the same trade on a different contract size

Example only. The dollar-account trade above needs 150 ounces. On a platform with 5,000-ounce lots that is 0.03 lots. On a platform with 1,000-ounce lots it is 0.15 lots. On a platform that counts in single ounces it is 150 units.

Now imagine a trader who learnt on the 1,000-ounce platform and moves to a 5,000-ounce one, still entering 0.15 lots out of habit. That is 750 ounces. The same 0.600 dollar stop now costs 750 × 0.600 = 450 USD, or 4.5% of a 10,000 USD account, on one trade, before slippage. This is the single most expensive silver mistake, and it is completely avoided by checking the contract size.

The position size calculator handles silver with a 5,000-ounce default and 0.001 pips; change the contract size if your broker's differs. The gold lot size calculator does the same for gold.

The gold/silver ratio, briefly

The gold/silver ratio is the gold price divided by the silver price: how many ounces of silver buy one ounce of gold. Example only: with gold at 3,600 dollars and silver at 40 dollars, the ratio is 90. The ratio has moved across a wide range over the decades.

Some traders watch the ratio to see which metal has been relatively stronger, and some trade it by buying one metal and selling the other. For sizing, remember that the two legs do not match by lot count. One lot of gold (often 100 ounces) and one lot of silver (often 5,000 ounces) carry very different dollar exposures and very different values per 1 dollar move: 100 dollars on the gold lot against 5,000 dollars on the silver lot. A ratio position is also two leveraged positions with two spreads, two swaps and two margin requirements, not a low-risk hedge. There is no "correct" level for the ratio, and its history is not a forecast.

Other costs on silver

Beyond the spread, a silver CFD can carry a commission on raw-spread accounts and an overnight financing charge (swap) on positions held past the daily rollover. On spot silver CFDs the swap is usually charged on the full position value, so on a 200,000-dollar exposure even a small daily rate adds up. Some providers offer futures-based silver CFDs that build the financing into the price instead and expire on a set date. Our guides to swap and overnight financing and to CFDs on stocks, indices and commodities explain both models.

Common mistakes with silver lot size

• Assuming one lot is 5,000 ounces everywhere. It often is, but not always. Check the specification on each account.
• Mixing up pip conventions. A 300-pip stop can be 0.30 dollars or 3.00 dollars depending on the platform. Think in dollars per ounce.
• Copying gold position sizes onto silver. One lot of gold at 100 ounces and one lot of silver at 5,000 ounces react very differently to the same move.
• Treating margin as the risk. Margin is a deposit; the risk is the stop distance times the ounces you hold.
• Rounding up. Always round down to the volume step, so the actual risk is at or below plan.
• Forgetting slippage and gaps. Silver can move fast around US data and at the weekly open. A stop is a trigger, not a guaranteed price; see our guide to gap risk and weekend risk.
• Ignoring the currency. In a non-dollar account, convert your risk into dollars before sizing, and remember that the result moves with the exchange rate.

Leverage magnifies losses as well as gains, and most retail CFD accounts lose money. Read our risk warning before trading silver CFDs.

Frequently asked questions

What is the pip value of XAG/USD?

On a 5,000-ounce standard lot, a 0.001 dollar move is worth 5 dollars and a 0.01 dollar move is worth 50 dollars. Whether your platform calls 0.001 or 0.01 a pip varies, so check the convention. On a 0.01 micro lot (50 ounces) the values are 0.05 and 0.50 dollars.

How many ounces is one lot of silver?

On many MetaTrader platforms one standard lot of silver is 5,000 troy ounces, matching the standard COMEX futures contract. Some providers use 1,000, 100, 50 or 1 ounce instead, and cent accounts scale sizes down. The symbol specification on your platform gives the exact figure.

How much is a 1 dollar move on silver worth?

On a 5,000-ounce lot, 5,000 dollars per lot. On 0.10 lots it is 500 dollars and on 0.01 lots it is 50 dollars. Multiply the dollar move by the number of ounces you hold.

How much margin do I need to trade silver?

For EU and UK retail clients, at least 10% of the position's value, because silver is capped at 10:1 leverage. Example only: at 40 dollars an ounce, 0.10 lots (500 ounces) is 20,000 dollars of exposure and needs at least 2,000 dollars of margin. Providers can ask for more.

Why is silver more volatile than gold?

Silver has a large industrial demand component that ties it to the economic cycle, and the silver market is much smaller in value than the gold market, so the same flows tend to move the price further. Historically that has meant larger percentage moves than gold in both directions.
