List of Option Queries KPIs

An option contract can either be of the type put or call. A put allows the buyer to sell 100 shared of the underlying stock to the option writer (or: option seller) at the strike price, when the strike price is reached. A call allows the buyer of the call to buy 100 shares of the underlying stock at the strike price, when the strike price is reached. In both cases, the buyer gives the option seller some premium (cash) for the risk.

Next, a list of Option Query KPIs that are supported by the platform is shown. All these KPIs can be used in different types of Queries to find interesting options or to alert when interesting events happen (such as unusual options activity). These KPIs are available for all query types.

KPIs	Description
ASK	Ask price of the option. This is the price people selling the option want. It is higher than the mid price.
BID	Bid price of the option. This is the price people buying the option offer. It is lower than the mid price.
ASKSIZE	The size of the ask, i.e. how many option contracts are on the ask.
BIDSIZE	The size of the bid, i.e. how many option contracts are on the bid.
AVERAGE_VOLUME	The average daily volume since the specific contract (e.g. AMZN210507C03400000) was first introduced.
CHANGE	Last day's price change in Dollars (e.g. -1.14$).
CHANGE_PERCENTAGE	Last day's change in percent (e.g. -4.5%).
CLOSE	Last (yesterday or today after end of trading hours) closing price.
HIGH	Highest price of today.
LOW	Lowest price of today.
LAST	Price of today's last trade.
LAST_VOLUME	Volume of today's last trade.
OPEN	Sometimes same as close - overnight prices may change too. Thus, this is the opening price of today.
OPEN_INTEREST	Total number of contracts written for the specific contract (e.g. AMZN210507C03400000) since it was first introduced.
VOLUME	Total volume of today thus far.
STRIKE	The fixed (strike) price at which the buyer of an option can buy or sell the underlying stock.

THETA	Rate of decline in the value of an option over time (also called time decay of an option).
VEGA	Change in the options price for a 1-point move in implied volatility (measures the sensitivity to Implied Volatility).
RHO	Sensitivity of an option to a change in the risk-free interest rate.
PHI	Sensitivity of an option to Dividends.
BID_IV	Implied Volatility of the bid price.
MID_IV	Implied Volatility of the mid price (average of bid and ask price).
