In finance, a calendar spread (also called a time spread or horizontal spread) is a spread trade involving the simultaneous purchase of futures or options expiring on a particular date and the sale of the same instrument expiring on another date. These individual purchases, known as the legs of the spread, vary only in expiration date; they are ...
The calendar call spread (see calendar spread) is a bullish strategy and consists of selling a call option with a shorter expiration against a purchased call option with an expiration further out in time. The calendar call spread is basically a leveraged version of the covered call (see above), but purchasing long call options instead of ...
Calendar spread - the purchase of an option in one month and the simultaneous sale of an option at the same strike price (and underlying) in an earlier month, for a debit. [5] Jelly roll - a combination of two calendar spreads, used to profit from changes in interest rates or dividends.
The simplest type of bid-ask spread is the quoted spread. This spread is taken directly from quotes, that is, posted prices. Using quotes, this spread is the difference between the lowest asking price (the lowest price at which someone will sell) and the highest bid price (the highest price at which someone will buy).
Disregarding interest on dividends, the theoretical value of a jelly roll on European options is given by the formula: = + + where is the value of the jelly roll, is the strike price, is the value of any dividends, and are the times to expiry, and and are the effective interest rates to time and respectively.
In finance, a spread trade (also known as a relative value trade) is the simultaneous purchase of one security and sale of a related security, called legs, as a unit.Spread trades are usually executed with options or futures contracts as the legs, but other securities are sometimes used.

The discrete difference equations may then be solved iteratively to calculate a price for the option. [4] The approach arises since the evolution of the option value can be modelled via a partial differential equation (PDE), as a function of (at least) time and price of underlying; see for example the Black–Scholes PDE. Once in this form, a ...
