Once you enter into the contract, you can't change the price.
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.
The holder/purchaser/owner of a call option contract has the right to buy an asset (or call the asset away) from a writer/seller of a call option contract at the pre-determined contract or strike price. The holder/purchaser/owner of a call option contract expects the price of the underlying asset to rise during the term or duration of the call contract, for as the value of the underlying asset increases so does the value of the call option contract. Conversely, the write/seller of a call option contract expects the price of the underlying asset to remain stable or to decline. The holder/purchaser/owner of a put option contract has the right to sell an asset (or put the asset) to a writer/seller of a put option contract at the pre-determined contract or strike price. The holder/purchaser/owner of a put option contract expects the price of the underlying asset to decline during the term or duration of the put contract, for as the value of the underlying asset declines the contract value increases. Conversely, the writer/seller of a put option contract expects the price of the underlying asset to remain stable or to rise.
The Payoff i.e. profit for a Call Option is St-X where St is the market price at time t and X is the exercise price. Assuming that it is an American Style option where it can be exercised at any time, If St is significantly greater than the exercise price,X, (the agreed price to buy an option at) then if the option holder exercises it immediately they will be 'in-the-money.' This means it has a high intrinsic value which causes a rise in value for the option. The Payoff for a Put Option is X-St where X=exercise price and St equals market price at time t. If the market price increases the gap between X and St (Payoff or Profit) reduces or if X<St then they will be making a loss. This will mean it will have a low intrinsic value (value if exercised immediately) therefore the value of the option will fall.
When a stock is at $10, a $9 strike price call option allows you to buy that stock at $9, which is $1 cheaper than the market price, hence it is in the money (ITM).Now, when a stock is $10, a $9 strike price PUT OPTION allows you to SELL that stock for $9 when you can actually sell it for $10, so there's no value in it, right? (why would anyone want to sell a stock at $9 when he can sell it for $10, right?) That is why it is out of the money (OTM).It is not an inconsistency but that you did not understand that options moneyness for call and put options are the reverse.
When you write a put option, you are player banker to someone betting that the price of a stock is going up. You receive the "bet" in the form of the options premium earned form the person buying the put options from you. If the stock fails to exceed the strike price of the put options by expiration, the buyer has lost the bet and you keep the "bet" money as profit. In this case, your profit is limited to the "bet" money or options premium you received for selling the put options. When you buy a call option, you are buying the right to buy a stock at a fixed price until expiration. If you buy a call option with strike price of $10 and the stock subsequently went up to $50, you can still buy the stock at $10 and then sell it for $50, making the $40 difference as profit. In this case, your profit is only limited to how high the stock rises.

We have two portfolios the first you have stock and put option with a strike price X for example ( $50 ). strategy of buying a call option with strike price X for example ( $50 ) in addition you buy a treasury bills with value equal to the exercise price of the call , and with maturity date equal to the expiration date of the two option . are you can pricing the put option if you know the call option price ?

What is the exercise price of the put?
In both cases, you will have to provide the stocks to the counterparty if the option is exercised. There are two differences. First is the nature of the option. Calls are exercised when the stock spot price exceeds the call's strike price. Puts are exercised when the stock spot price is below the put's strike price. The other is, if you write a call you don't get to decide whether it gets exercised--the buyer does. If you buy a put, the choice to exercise it is yours.
'Put-call parity' is a popular term used among investments. The 'put-call parity' concept is used to describe a relationship between the price of a call and put option.
A call option gives the option buyer the right, but not the obligation, to buy a certain amount of stock on or before a certain date for a certain price. A put option gives its buyer the right, but not the obligation, to sell stock on or before a certain date for a certain price. How the options are exercised is another difference. If you bought a put, you're hoping the stock price falls below the strike price--the certain price in the contract. It would make no sense to sell stock for $10 a share if it's $15 now, right? Calls exercise when their stock price goes above the strike price.
Yes, and it's massive. If you buy a call, the option exercises if the stock price is higher than the strike price. If this happens, you resell the stock and keep the profit. If you sell a put, the option exercises if the stock price is below the strike price. If this happens, you bury the stock in the back yard until the price goes back up.
Exercising an option means exercising your rights to buy or sell the underlying asset in accordance to the parameters of the option. When you exercise a call option, you will get to buy the underlying stock at the strike price no matter what price the stock is trading at in the market. When you exercise a put option, you will get to sell the underlying stock at the strike price no matter what price the stock is selling at in the market. In both cases, the option you own disappears from your account.
The strike price is the heart of the futures market. If you are dealing in puts, the strike price is the price below which the option exercises. If I sell a put on Acme at $10, I can be required to buy the security if it falls to $9.95. In calls, if the share price goes above the strike price the option exercises--if I sell a call on Acme at $10, the option executes if the share price hits $10.05.
"In the Money" is a term used in option trading as a determinate to if an option has "Intrinsic Value." In the Money, does NOT mean in profit. There are two components to an option value, TIME VALUE, and INTRINSIC VALUE. Time Value + Intrinsic Value = Option Premium. When the market price is above the option strike price of a CALL option, that option is considered "In the Money" i.e. having intrinsic value. When the market price is below the option strike price of a PUT option, that option is considered "In the Money" i.e. having intrinsic value.
Put options refers to an option of selling stock at a specific price on or before a certain date, similar to that of insurance policies. While, Call options are options to buy stock at a specified price on or before a certain date, similar to security deposits.
