Read the silver contract correctly and understand why silver swings harder than gold on the same chart.
Silver: the metal with two jobs
Silver trades on COMEX under the symbol SI. One contract represents 5,000 troy ounces — way more ounces than a gold contract — but at a much lower per-ounce price. At $30 an ounce, one SI contract controls $150,000 worth of silver. The tick size is 0.005 (half a cent), and because the contract is 5,000 ounces, each tick is worth $25.
Here's what makes silver different from gold: roughly half of all silver demand is industrial. Solar panels are the biggest growth driver — every photovoltaic cell uses a tiny amount of silver for conductivity. Electronics, EV components, medical applications, brazing alloys, even mirrors. So silver isn't only a hedge against currency debasement — it's also a bet on factories running, on solar buildouts, on tech cycles.
For a $500 account, full-size SI is overkill — $25 a tick adds up fast in a volatile instrument. The cleaner choice is SIL (micro silver), which is 1,000 ounces per contract and $5 per tick — one-fifth the size. Even better, you can paper-trade SIL in the simulator until the volatility doesn't catch you off guard. Silver will absolutely punish a trader who treats it like gold's little sibling.
Recap: SI is 5,000 oz, $25 per tick. Half industrial demand makes silver more volatile than gold. Start with SIL (1,000 oz, $5/tick) and never assume gold's playbook fits silver one-for-one.
Knowledge check
Answer before moving on.
1. Gold has a quiet 0.4% day. Silver has a 1.1% day. Why?
2. You buy one SI contract at 30.00 and sell at 30.50. How much did you make?
