In general, finite difference methods are used to price options by approximating the (continuous-time) differential equation that describes how an option price evolves over time by a set of (discrete-time) difference equations. The discrete difference equations may then be solved iteratively to calculate a price for the option. [4]
The most bearish of options trading strategies is the simple put buying or selling strategy utilized by most options traders. The market can make steep downward moves. Moderately bearish options traders usually set a target price for the expected decline and utilize bear spreads to reduce cost.

A long butterfly options strategy consists of the following options: Long 1 call with a strike price of (X − a) Short 2 calls with a strike price of X; Long 1 call with a strike price of (X + a) where X = the spot price (i.e. current market price of underlying) and a > 0. Using put–call parity a long butterfly can also be created as follows:
This setup works similarly to buying call options. 2. Go short futures. When you sell, or “go short,” futures, you’re making a directional bet on the deliverable, expecting its price to fall ...

In finance, the binomial options pricing model (BOPM) provides a generalizable numerical method for the valuation of options.Essentially, the model uses a "discrete-time" (lattice based) model of the varying price over time of the underlying financial instrument, addressing cases where the closed-form Black–Scholes formula is wanting, which in general does not exist for the BOPM [1].
Exchange-traded derivative contracts [1] are standardized derivative contracts such as futures and options contracts that are transacted on an organized futures exchange.They are standardized and require payment of an initial deposit or margin settled through a clearing house. [2]
