SI quote units, tick value and point value
This is the standard COMEX SI contract: 5,000 troy ounces per contract, quoted in US dollars per troy ounce. Each amount below is the value of a price change for one contract.
- Outright minimum tick: $0.005/troy oz × 5,000 troy oz = $25 per contract.
- A $0.01/troy oz move (one US cent) is $50 per contract.
- A $1.00/troy oz move (one full price point here) is $5,000 per contract.
These amounts are not margin or a current quote. Spread and TAS increments require their own official specifications; do not apply these SI values to other silver contract sizes or CFDs.
