Future Call ratio spread debit indicator developed by Chobotaru Brothers.

You need to have basic knowledge in option trading to use this indicator!
This spread is a DEBIT SPREAD.
The indicator shows P&L lines of the options strategy. Use only for stocks since the mathematical model of options for Future instruments is different from futures . Plus, the days' representation in futures is also different from stocks (stocks have fewer days than futures ).

***Each strategy in options is based on different mathematical equations, use this indicator only for the strategy in the headline.***

What does the indicator do?

The indicator is based on the Black-Scholes model, which uses partial differential equations to determine the option pricing. Due to options non-linear behavior, it is hard to visualize the option price. The indicator calculates the solutions of the Black-Scholes equation and plots them on the chart so traders can view how the option pricing will behave.

How the indicator does it?

The indicator uses five values (four dominants and one less dominant) to solve the Black-Scholes equation. The values are stock price, the strike price of the option, time to expiration, risk-free interest rate, and implied volatility .

How the indicator help the users?
