Silver vs gold
Silver is often described as gold's smaller sibling. That undersells the differences, and one of them will cost you money if you assume the two instruments size the same way.
Silver appears as XAG/USD, priced in dollars per troy ounce, on exactly the same basis as gold. AG is the chemical symbol, the X marks it as a non-national currency, and buying it means long silver and short dollars.
Everything about reading the quote works as Gold trading 101 described. The similarity stops at the contract.
Contract size explained
A standard silver lot covers 5,000 troy ounces. Gold's covers 100.
Fifty times the quantity, on an instrument that costs a small fraction of gold per ounce.

Read the bottom row against gold's. One cent of silver movement on a minimum lot is $0.50. One cent of gold movement on a minimum lot is one cent. The same nominal position size is a completely different exposure.
Silver's percentage moves are also larger than gold's, so you're applying a bigger contract to a more volatile instrument. That combination is why silver catches out traders who have grown comfortable with gold.
Sizing a silver trade
Anna has $3,000 and risks 1%, so $30.
Her stop sits $0.60 below entry, which is a modest move by silver's standards.
Risk per lot = $0.60 × 5,000 ounces = $3,000
$30 ÷ $3,000 = 0.01 lots
The platform minimum, using her entire risk allowance on a sixty-cent stop.
Widen the stop to $1.20 and the calculation asks for 0.005 lots, which most platforms won't accept.
That's the honest position: silver on a small account runs into the minimum position size almost immediately. Risk per trade: the 1% rule and position sizing named this constraint, and silver is where it bites hardest of any instrument in this course. Anyone trading silver with a few thousand pounds is either using very tight stops or exceeding their intended risk, and it's worth knowing which.
Why silver behaves differently
Gold is a monetary asset that happens to be a metal. Silver is genuinely both.
Roughly half of silver demand is industrial, and that share has grown. It's used in solar panels, electronics, electrical contacts, brazing alloys and medical applications, because it's the best electrical and thermal conductor of any element.
Which gives silver a second driver gold doesn't have. When manufacturing activity is strong, industrial silver demand rises regardless of what interest rates are doing. When a recession is anticipated, that demand falls, at exactly the moment the monetary argument for precious metals might be strengthening.
The consequence: silver is pulled in two directions. It responds to the real interest rate and safe-haven story covered in What drives precious metals, and simultaneously to the industrial cycle that moves copper. In a risk-off episode driven by growth fears, gold can rise while silver falls, and both are behaving logically.
Volatility
Silver moves more than gold, typically by a meaningful multiple, and for two structural reasons.
The market is smaller. Total silver market value is a fraction of gold's, so the same flow of money produces a larger price effect.
Two demand drivers instead of one. Industrial and monetary demand can reinforce each other, and when they do, moves are amplified.
Practically, this means wider spreads than gold, larger daily ranges, and stops that need more room. It also means silver punishes a sizing error faster.
The gold-to-silver ratio
A widely watched number: how many ounces of silver it takes to buy one ounce of gold.
It's calculated by dividing the gold price by the silver price, and it's used as a relative value measure. A high ratio suggests silver is cheap relative to gold, a low ratio the reverse.
Two honest caveats, because the ratio is often presented with more confidence than it deserves.
It has no fixed anchor. The ratio has ranged enormously across history, from historic monetary standards that fixed it, through modern periods where it has moved across a very wide band. There's no level it must return to.
It can stay stretched for years. A ratio that looks extreme is not a trade. It's a piece of context, and treating it as a signal has cost people a great deal of money waiting for a reversion that had no deadline.
Use it to understand which metal is outperforming and why. Don't use it to predict when that will stop.
Which should you trade?
For most traders building a process, gold first.
It's more liquid, its spread is tighter relative to its movement, its contract size is more forgiving, and it has one dominant driver rather than two competing ones. Silver rewards a trader who already understands the precious metals story and can size for higher volatility. It punishes one who is still learning either.
If you trade both, remember they're strongly correlated. Long gold and long silver is largely one position, which is the correlation problem Managing leverage as a beginner covered, and your real exposure is the sum.
Key takeaways
A standard silver lot covers 5,000 troy ounces against gold's 100, so the same nominal position size is a vastly different exposure
On a small account silver hits the minimum position size almost immediately, which means very tight stops or exceeding your intended risk
Around half of silver demand is industrial, giving it a growth-cycle driver gold lacks. Gold can rise while silver falls, and both are behaving logically
The gold-to-silver ratio is context, not a signal. It has no level it must return to and can stay stretched for years
