What Is a Scanner?

It eliminates the routine review of stock prices, filtering them by set parameters.
The Thinkorswim scanner script impartially tracks everything that interests a trader and leaves out a lot of unnecessary information.

What Is a Call Option in Options Trading?
A call option is a type of options contract that gives the buyer the right, but not the obligation, to buy an underlying asset at a predetermined price.
The buyer of a call option pays a premium to the seller, also known as the writer, for this right.
Call options can be used to speculate on a price increase, hedge against a potential loss, or generate income through selling options contracts.

To exercise a call option, the buyer must notify the seller before the expiration date, and the seller is obligated to sell the underlying asset at the strike price.
The strike price is the predetermined price at which the buyer can buy the underlying asset, and it's usually set by the seller when creating the options contract.
A call option's premium is determined by several factors, including the underlying asset's price, volatility, time to expiration, and interest rates.
The buyer can choose to let the call option expire worthless if the underlying asset's price falls below the strike price.
In the context of scanner functions, understanding call options is crucial for traders who want to monitor and analyze market trends, identify potential trading opportunities, and make informed decisions.
