There are many types of Option strategies, Some are Naked, some Hedged. Some involve Option buying, some involve Option selling and some involve both.

Option buying is like buying a Lottery ticket, where the chances of winning Big is very little. On the other hand, Option Selling is considered as a steady business in which the chances of winning Huge is not there but the chances of making steady money are there.

Buying or Selling options make in a Naked Option strategy where the trader makes a profit only when his anticipation is right or else he might face a loss. Naked option strategies can be used only for a Directional view.

To cover these shortcomings of naked options trading, one used more than 1 Option is used to form a Strategy that can be deployed in every type of scenario, be it Bullish, Bearish, or Neutral.

Similarly, Every Option Strategy has the 3 main aspect-

  1. OTM- Out of The Money
  2. ITM - In The Money.ATM
  3. ATM- At The Money

These factors determine the overall profitability and the overall risk factor of any option strategy.

To Find out how the total Profitability and total risk changes by shifting Strike prices of an Option, One needs to backtest the strategies by applying their required Strike prices,

This can be done in multiple software that is available for free, but the most commonly used is Opstra Define edge and Sensibull, where you can seamlessly create option strategies and backtest them.

In Opstra, One can add various options to form your own Option strategies or modifies the Strike prices and Number of Lots in each Strategy.

For Example-

In an Iron Condor-
1 Slightly OTM(Out of The Money) Call and 1 slightly OTM Put option is Sold and
1 OTM (Out of The Money) Call & 1 OTM Put is bought.

In this strategy, the maximum profit is got when the underlying asset expires someplace in Between the Sold Call & Put option. Now if the Trader wants to Choose a Farther or nearer Strike Price, they can adjust the Strike Price in Opstra and it will automatically show the Breakeven and the total Margin required along with the maximum Profit & Loss.
It will also show the Difference in the Payoff Graph.

Let’s take Nifty as an example and apply an Iron Condor-

  1. In the First case the iron Condor has been set and the Options that are bought are around 200 points away from the Option Sold. The result is shown in the Graph Below.

2.Now if the Hedge is Shifted another 100 points, the following difference can be seen below-

As visible above the total Profit changed from 4700 to 7900. The Total Credit changed from 4713 to 7995 and the total margin increased by 10,000 in the latter.
In this way, a Trader can backtest various options strategies along with tweak the Strike prices and other factors based on their requirements.
