These definitions concern all derivatives tables :

**Number of contracts traded**

A contract is a standard unit of trading denoted by the number of shares or the amount of capital that may vary from class to class, or from product to product, as defined by an exchange.

**Notional Value**

The notional value of derivatives is the number of contracts traded multiplied by the contracts’ underlying value. The contracts’ underlying value is calculated by multiplying the market price of the underlying asset for each contract times the contract’s multiplier. It is an approximate measure of the underlying value of the number of contracts traded.

**Open**** interest**

It is the number of derivatives contracts (futures and options) outstanding at a given time (close of trading at the last trading day of the month). It may be computed on a net or gross basis, according to the way the opening/closing of position by the same trader is managed at the clearing level. This is usually used in analysis of liquidity and market size.

**Option**** Premium**

The option premium represents the money paid by buyers to writers of calls or put options.

The premium turnover for each trade is computed by multiplying price by volume by lot size.

Day premium turnover is the cumulative value of each trade.
