An American put option can be exercised at any time during its life. The European put option can only be exercised at the end of the contract period.
In finance, an American option is an option which can be exercised at any date between the issue date and the expiry date.
A call option allows its purchaser to buy ("call in") stocks at a certain price on a certain date--say, 100 shares of Walmart for $50 on November 1. A put option allows its purchaser to sell ("put") stocks on a certain price for a certain date. The seller of the option has to buy them (in a put) or sell them (in a call) if the option is exercised.
An option buy is when you buy an option, whether call option or put option, using the Buy To Open order.
The only difference between American Options and European Options is that the American Option allows you to exercise the option anytime before and up to expiration while European options only allow you to exercise the option upon expiration. Both options can be freely bought and sold before expiration.
A Put option
When you buy an insurance on your asset, you are essentially buying a put option on your asset for protection much like the Protective Put options trading strategy. As such, to the insurer, they are actually selling a naked put option to the buyer of the insurance.
A European put has an exercise window. Let's say it's a week, at the end of the contract. You can exercise the put only within that window. An American put has no exercise window. If you bought a three-month put at 43 and, the next day, the stock price drops to 32, you can exercise it at that time.
Stock option agreements are what you apply before you actually put money on the market. it is the finalization before you put your business out there. You can choose from many.
A put option or a put is a contract between two parties made so that they can exchange assets. They set a specific price for it and set a specific date of expiry or maturity.
