Premium, as it pertains to the Unusual Whales platform, may be used in several different contexts.

Premium is found as a column header in the flow feed. It represents the total dollar value of the respective options transaction. The premium value is derived from multiplying the spot price of the respective contract by the total size of the trade. 

A ticker's overall trading activity can be broken up into call and put premium, as well as bullish and bearish premium.

A ticker's call premium is the total value of all call activity. 

A ticker's put premium is the total value of all put activity.

A ticker's bullish premium is the total value of ask-side call and bid-side put activity.

A ticker's bearish premium is the total value of ask-side put and bid-side call activity.

A ticker's neutral premium is the total value of trades occurring at the mid as well as: cross trades, trades that have been modified/cancelled, or reported late.

Net Premium is a concept derived from the Market Tide and Net Flow feature. 

Net Call Premium is the premium value derived from the daily call activity using the following example:

- $15,000 in calls transacted at the ask has the effect of increasing the daily net call premium by $15,000. 

- $10,000 in calls transacted at the bid has the effect of decreasing the daily net call premium by $10,000.

The resulting net premium from both of these trades would be $5000 (+ $15,000 - $10,000).

Transactions taking place at the mid are not accounted for.

Net Put Premium is the premium value derived from the daily put activity using the same example as above.
