Options trading is a powerful way to capitalize on market movements, but it requires the right tools and analysis. In this guide, we’ll break down key indicators like Open Interest (OI) , Put-Call Ratio (PCR) , and VIX (Volatility Index) to help you make informed trading decisions. We’ll also explore additional factors like Max Pain, support and resistance levels , and the best indicators to use alongside option chain analysis. 1. Understanding Open Interest (OI) What is Open Interest? Open Interest (OI) represents the total number of outstanding option contracts that haven’t been squared off. It shows the liquidity and market interest in a particular strike price. How to Use OI for Trading? Increasing OI with rising price: Strong bullish trend (new buyers entering the market). Increasing OI with falling price: Strong bearish trend (new sellers entering the market). Decreasing OI with rising price: Weakening bullish trend (short covering). Decreasing OI with falling price: Wea...

Debugging code can be frustrating, especially when you’ve stared at your screen for hours and still can’t figure out what’s wrong. But what if the key to solving your bug was sitting right on your desk—a rubber duck ? 🦆 Yes, you read that right! Rubber Duck Debugging is a powerful technique used by developers worldwide to debug their code simply by explaining it—often to a rubber duck or any other inanimate object. Let’s dive into how this works and why it’s so effective. What is Rubber Duck Debugging? Rubber Duck Debugging is a problem-solving method where you explain your code, line by line, as if you were teaching it to someone who knows nothing about programming. The catch? That “someone” can be a rubber duck , a stuffed toy, or even an imaginary friend. The term originated from the book The Pragmatic Programmer by Andrew Hunt and David Thomas, where a programmer carried around a rubber duck and explained code to it whenever they faced an issue. How to Use Rubber Duck Debug...

Tracking down a bug in a large codebase can be frustrating. **Git bisect** helps by using a binary search to quickly find the exact commit that introduced the issue. ## Step 1: Start Git Bisect Begin by starting bisect mode: ```sh git bisect start ``` ## Step 2: Mark a Good and Bad Commit Specify a known working commit: ```sh git bisect good a1b2c3d ``` Mark the current commit (where the bug exists) as bad: ```sh git bisect bad ``` ## Step 3: Test and Mark Commits Git checks out a middle commit. Run your app and test it: ```sh ./gradlew bootRun ``` If the bug exists: ```sh git bisect bad ``` If the bug is not present: ```sh git bisect good ``` ## Step 4: Find the Bad Commit Once Git finds the problematic commit, it displays: ```sh 1234567 is the first bad commit ``` ## Step 5: Reset Git Bisect Once the issue is identified, reset bisect mode: ```sh git bisect reset ``` ## Conclusion Using **git bisect** can save you hours when debugging! Instead of checking each commit manually, bisect ...

Understanding API Parameters in Spring Boot When designing APIs in Spring Boot, it's essential to understand how to handle different types of parameters. These parameters define how data is sent from the client to the server. Let's break down the common types of parameters used in API development, with examples and cURL commands. 1. Types of Parameters Parameter Type Location Use Case Example Format Annotation in Spring Boot Query Param URL after `?` Filtering, Pagination ?key=value @RequestParam Path Param In the URL path Identifying specific resource /resource/{id} @PathVariable Form Param Form-encoded body Simple form submissions ...
