Episode 6 - Strategy 1 for Intraday Trading

By Santhosh S • January 26, 2025
9:30 AM Strategy for Intraday Trading Hello everyone, and welcome back to our intraday trading series! In this blog post, I'll explain the 9:30 AM strategy for intraday trading. Disclaimer: I am not a SEBI-registered trader. These strategies are based on my experience, so please back-test them and apply your strategies accordingly. What is the 9:30 AM Strategy? The 9:30 AM strategy involves using the first 15 minutes of the trading day to identify potential entry and exit points. Here’s how it works: 5-Minute Candle Analysis Start by analyzing the 5-minute candles from 9:15 AM to 9:30 AM. This includes the 9:15, 9:20, and 9:25 candles. Mark the high and low of these three candles. Identify Breakout Points Wait for a breakout either above the high or below the low of the marked candles. The first candle to close above the high or below the low is your signal candle. Confirmation Candle Wait for the next candle to confirm the breakout by moving in the same direction as the signal candle. If the confirmation candle breaks the high or low of the signal candle, it indicates a potential trade opportunity. Take the Trade Enter the trade based on the direction of the confirmation candle. Set your stop-loss slightly above or below the opposite end of the signal candle to manage risk. Select Suitable Stocks Focus on stocks with a daily price movement between 1% to 2%. This ensures manageable volatility and reduces the risk of significant capital loss. Practical Example Example 1: On January 24, 2025, mark the high and low of the 9:15, 9:20, and 9:25 candles. If the low is broken by the next candle, wait for confirmation. Once confirmed, enter a sell trade and set your stop-loss. Example 2: For another stock, mark the high and low as before. If the high is broken and confirmed, enter a buy trade and set your stop-loss accordingly. By following this strategy, you can effectively capitalize on early market volatility. Always remember to practice discipline and patience, and happy trading! Feel free to leave your questions in the comments, and I'll be happy to answer them. 📈💼

Episode 5 - Money Management for Intraday Trading

By Santhosh S • January 26, 2025
Money Management for Intraday Trading Hello everyone, good day! Welcome back to our series on intraday trading. In this blog post, we'll discuss the crucial topic of money management. Disclaimer: I am not a SEBI-registered trader or influencer. I am sharing my knowledge based on my experience. Importance of Money Management Money management is vital when it comes to trading in the stock market. If someone tells you that you can double, triple, or quintuple your money easily, do not fall for it. Treat the stock market as a business, not gambling. Key Principles of Money Management Avoid Loans Do not take loans for trading until you have become a professional trader. Use only your own capital, which should be a small, manageable amount that you can afford to lose. Start Small Begin with a small amount of capital based on your financial capacity. Invest this money in trading after you have learned the basics of the stock market. Allocation Strategy If you have a total investment of ₹10,000, start by using only 10% (₹1,000) for trading. Once you make a profit, reinvest 70% of the profit back into your capital and keep 30% as a buffer for potential losses. Compound Your Gains Reinvest your profits to compound your gains over time. This approach will help grow your capital steadily and sustainably. Practical Example Suppose you have ₹10,000 to invest. Initially, use ₹1,000 for trading. If you make a profit, reinvest 70% and keep 30% as a buffer.  Final Thoughts Remember, there is no one-size-fits-all strategy. Everyone can create their own strategies based on their experiences. A success rate of 80% is considered excellent in the stock market. Stay disciplined and stick to your strategy. By following these money management principles, you can navigate the stock market more effectively and increase your chances of long-term success. Happy trading! 📈💼

Episode 4 - Trading Mindset for Intraday Trading

By Santhosh S • January 26, 2025
Developing the Right Mindset for Intraday Trading Hello everyone! Welcome back to Sandy E-learning. Continuing from our previous discussions on intraday trading prerequisites, let's now focus on developing the right mindset for trading. Disclaimer: I am not a SEBI-registered trader. I am sharing my knowledge based on my experience. If I make any mistakes, please let me know, and I will correct them. Trading Mindset There's a quote I live by: "Trading is a business, not gambling." It's important to remember this before starting your trading journey. Why Mindset Matters As mentioned in previous videos, nine out of ten traders fail. To be part of the successful 10%, you need the right mindset. You cannot expect to earn 100% profits every day in the stock market. Avoid treating trading like a lottery. Instead, approach it as a business. Profit Expectations Set realistic profit expectations. For example, if you aim for a 1% stock movement daily, you can achieve a 5% profit in a single trade. Over a month (20 trading sessions), this could result in a 100% profit on your capital. Patience is key. Key Principles Avoid Greed Don't chase unrealistic profit margins. A steady, consistent approach yields better long-term results. Patience Wait for the right opportunities to enter and exit trades. Avoid impulsive decisions. Weekly and Monthly Analysis Instead of daily profit calculations, focus on weekly and monthly performance. A 20-30% monthly profit indicates a successful trader. Control Emotions Money can evoke strong emotions. Avoid making trades based on greed or fear. Stick to your strategy and remain disciplined. Brokerage Charges Remember to account for brokerage charges. For example, if you earn ₹1,000 in profit, but brokerage fees are ₹300, your net profit is only ₹700. By maintaining a business mindset and focusing on percentage-based profits, you can navigate the stock market more effectively. Always remember that trading is a disciplined business, not a gamble. I hope this helps clarify how to approach intraday trading with the right mindset. Happy trading! 📈💼 Feel free to leave your questions in the comments, and I'll be happy to answer them.

Episode 2 - What is Intraday Trading?

By Santhosh S • January 26, 2025
What is Intraday Trading? Welcome back to Sandy e-learning! In this blog post, we're going to delve into the world of intraday trading. Before we start, here's a quick disclaimer: I am not a SEBI-registered trader. I'm sharing my knowledge based on my experience, so always back-test and gain experience before relying on my teachings. Test it out and see if it works for you. What is Intraday Trading? Intraday trading involves buying and selling financial instruments within the same trading day. Unlike investors who hold stocks or futures for the long term, intraday traders capitalize on short-term price movements. Investor vs. Trader An investor holds stocks or futures (F&O) for more than one day, often ignoring daily market fluctuations. They invest with a long-term perspective and sell when they achieve their desired profit. On the other hand, a trader buys and sells within the same day, booking profits from short-term price changes. For example, a trader might buy a stock at 9:15 AM and sell it at 9:17 AM for a small percentage profit. Understanding Intraday Trading Intraday trading means completing all transactions within the same day. In India, the stock market operates from 9:15 AM to 3:30 PM. Trades must be completed before 3:20 PM to avoid automatic closure by brokers. Advantages of Intraday Trading Profit from Both Rising and Falling Markets : You can buy low and sell high, or sell high and buy low to profit from price movements. Leverage : Intraday traders can buy more stocks with less capital due to margin trading. For example, with ₹5,000, you can buy five stocks for delivery trading or up to 25 stocks for intraday trading. Example Let's say a stock like Reliance is trading at ₹1,000. If you expect the price to rise by ₹10, you can buy at ₹1,000 and sell at ₹1,010. Conversely, if you expect the price to fall to ₹980, you can sell first and buy later at the lower price, pocketing the difference. Intraday trading provides opportunities for higher percentage gains compared to holding stocks for delivery. If a stock rises by 1%, the intraday profit might be 5%.  Remember, trading is a business, not gambling. Always back-test strategies and maintain a disciplined approach. Happy trading! 📈💼Understanding Intraday Trading

Getting Started with Terraform

By Santhosh S • September 6, 2024
In today’s world of cloud computing, Infrastructure as Code (IaC) has become a cornerstone of automating and managing IT infrastructure. One of the leading tools in this space is Terraform, developed by HashiCorp. It allows users to define and provision infrastructure using a high-level configuration language. In this blog, we'll walk you through the basics of Terraform and show you how to get started with it. What is Terraform? Terraform is an open-source IaC tool that allows you to manage cloud resources like virtual machines, networking, and storage, all by writing simple configuration files. It supports multiple cloud providers, such as AWS, Azure, Google Cloud, and even on-premises infrastructure. Why Use Terraform? Multi-cloud support: Manage resources across different cloud providers with a single tool. Idempotency: Apply the same configuration multiple times without changing already up-to-date infrastructure. Versioning: Keep track of your infrastructure changes. Infrastructure as Code: Codify your infrastructure, enabling reusability, consistency, and collaboration. How Terraform Works At a high level, Terraform works in three main stages: Write: Define your infrastructure as code in .tf configuration files. Plan: Generate an execution plan that previews what Terraform will do. Apply: Execute the plan to create or modify the infrastructure. Now that you know the basics, let’s get started with Terraform. Step 1: Install Terraform Before using Terraform, you need to install it on your local machine. You can download it from the official website and follow the installation instructions based on your OS (Windows, macOS, or Linux). To verify the installation, run the following command in your terminal

Understanding Virtual Machines: A DevOps Journey

By Santhosh S • September 5, 2024
In today's session, we'll dive into a key foundational concept in the world of DevOps: Virtual Machines (VMs). If you're still a bit unsure about what virtual machines are or how they differ from physical servers, don't worry—we'll break it down in simple terms. We'll also connect the dots between VMs and the broader goal of DevOps: improving efficiency in managing software infrastructure. Real-World Example: The Land and House Analogy Let’s start with a real-world analogy. Imagine you own a piece of land, say, one acre. You build your dream house on this land, and you're enjoying it with your family. But one day, you realize you're only using half of the available space, while the other half is just sitting idle. To make better use of the space, you decide to build a second house on the unused portion of your land and rent it out. Now, you’re using your land more efficiently, sharing resources like water and electricity while maintaining your privacy and comfort. Translating to Technology: Physical Servers and Virtual Machines In the world of technology, the "land" represents a physical server. Think of physical servers as large, powerful computers that host applications and store data. Initially, you might deploy one application on one physical server, just like how you built one house on your land. However, this setup can lead to underutilized resources. For example, if the application only needs 4GB of RAM and four CPUs, but the server has 100GB of RAM and 100 CPUs, you're wasting a lot of computing power. This inefficiency is where virtualization comes into play. Just like building another house on your land to make better use of space, virtualization allows you to create multiple virtual machines (VMs) on a single physical server. These VMs act like independent computers, each with its own resources (CPU, memory, etc.), but they’re all running on the same physical hardware. What Is a Virtual Machine? A virtual machine is a software-based emulation of a physical computer. It has its own CPU, memory, storage, and network interface but runs on shared physical hardware. Virtual machines are created using a special software called a hypervisor. The hypervisor partitions the physical server into multiple isolated environments (VMs), allowing different teams or applications to use the server efficiently without stepping on each other's toes. For example, a physical server might be divided into five virtual machines, each allocated a portion of the CPU, memory, and storage. Team A can use VM1, Team B can use VM2, and so on, without any interference between them. This ensures that the resources are used effectively, avoiding waste. Benefits of Virtual Machines in DevOps Efficiency: Virtualization maximizes resource utilization. By running multiple VMs on a single physical server, you ensure that your hardware is fully utilized. This is critical in DevOps, where efficiency is the primary goal. Isolation: Each virtual machine operates independently. If one VM experiences an issue, it doesn’t affect the others, ensuring stability in your system. Scalability: Need more computing power? With virtualization, you can easily create new VMs or scale existing ones without having to invest in new hardware. Cost-Effectiveness: By using virtual machines, companies save money on hardware, maintenance, and energy costs, as fewer physical servers are needed. The Role of the Hypervisor The hypervisor is the unsung hero behind virtualization. It’s a piece of software that sits between the physical server (hardware) and the virtual machines, managing the allocation of resources. Popular hypervisors include VMware and Xen. The hypervisor ensures that each VM gets its fair share of CPU, memory, and storage without conflict, allowing multiple virtual machines to run smoothly on one physical server. Virtual Machines in the Cloud Cloud providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud rely heavily on virtualization. They use massive data centers filled with physical servers, but they provide customers with virtual machines. This allows companies to rent computing power as needed, without having to own or maintain the physical servers themselves.

Azure Delete / Stop instance Billing impact

By Santhosh S • September 4, 2024
In Azure, when managing resources, the terms "Delete" and "Stop" have different implications, especially concerning costs: Stop Virtual Machines (VMs): When you stop a VM in Azure, it is deallocated. This means that the compute resources (like CPU and RAM) are released, and you are no longer charged for these resources. However, the storage associated with the VM (like OS disks, data disks, and reserved IP addresses) is still retained, and you will continue to incur storage costs. App Services: If you stop an Azure App Service, the app is no longer running, and you won’t be charged for the compute resources. However, as with VMs, you’ll still be charged for any storage and other resources that are associated with the service. Key Consideration: Stopping resources is a good option if you plan to resume them later and want to avoid the hassle of reconfiguration. However, you must still pay for the storage costs or other associated resources. Delete Virtual Machines (VMs): When you delete a VM, all associated compute resources and any associated temporary storage are removed. If you choose to delete the underlying disks and other resources, they will be completely removed, and you won’t be charged anymore. However, if you keep the storage resources (like disks or backups), you’ll still incur charges for those. App Services: Deleting an App Service will remove the app and all associated configurations. If there are no other resources attached, you won’t be charged any further. However, if associated storage or other resources are not deleted, they may continue to incur charges. Key Consideration: Deleting is the best option if you are sure you no longer need the resource, as it will stop all associated charges. However, once deleted, recovering the resource can be difficult or impossible, depending on the Azure service. Summary Stop: No compute charges, but storage and other associated costs remain. Delete: No charges for the resource, but be cautious about any retained associated resources. If you want to minimize costs and don't need the resource anymore, Delete is the safest choice. If you think you may need the resource again in the future, Stop is a better option, keeping in mind the ongoing storage costs.

Improve SDLC with DevOps

By Santhosh S • September 4, 2024
The Software Development Lifecycle (SDLC) is a fundamental concept in the software industry, crucial for professionals across all domains, including developers, testers, software engineers, and especially DevOps engineers. Understanding SDLC is essential to delivering high-quality software products efficiently and effectively. What is SDLC? SDLC stands for Software Development Lifecycle, a structured process followed by the software industry to design, develop, and test high-quality software products. It serves as a blueprint for producing software that meets or exceeds customer expectations. Whether you're working at a startup, an MNC, or a unicorn, understanding SDLC is critical for contributing effectively to any software project. Why is SDLC Important? Regardless of your role—be it a developer, tester, or DevOps engineer—comprehending SDLC is imperative. SDLC ensures that software products are developed in a systematic, efficient manner, leading to the delivery of high-quality products. It encompasses various stages, each playing a vital role in the overall software development process. The Phases of SDLC Let's delve into the different phases of SDLC, each of which is crucial for the successful delivery of a software product. 1. Planning and Requirements Gathering The first phase of SDLC involves planning and gathering requirements. This stage is critical as it lays the foundation for the entire project. Here, business analysts or product owners collect input from customers and stakeholders to define the software's goals. This phase ensures that all necessary requirements are captured, which helps in avoiding costly revisions later in the process. 2. Defining Requirements Once the requirements are gathered, the next step is to define them clearly. This involves creating detailed documentation, often called the Software Requirements Specification (SRS) document. The SRS serves as a reference point for all future stages of the project, ensuring that everyone involved has a clear understanding of what the software should accomplish. 3. Designing the Software The design phase is where the actual blueprint of the software is created. This phase is divided into two parts: High-Level Design (HLD) and Low-Level Design (LLD). High-Level Design (HLD): In this stage, architects and senior team members outline the overall system architecture. They focus on scalability, availability, and the technologies to be used, such as databases, application servers, and cloud infrastructure. Low-Level Design (LLD): Here, the focus shifts to more detailed design aspects. Developers plan out the specific modules, functions, and interfaces that will be used. The LLD provides a clear path for developers to follow during the coding phase. 4. Building the Software The building phase is where the actual coding takes place. Developers write the code based on the specifications laid out in the design phase. This stage is crucial for translating the design into a functional software product. 5. Testing the Software Once the software is built, it needs to be tested to ensure it meets the defined requirements. Testing helps in identifying and fixing bugs before the software is deployed. This phase is essential for delivering a high-quality product that meets customer expectations. 6. Deploying the Software After successful testing, the software is deployed to a live environment where it can be accessed by end-users. This phase involves setting up the necessary infrastructure and ensuring that the software runs smoothly in the production environment. 7. Maintenance and Updates SDLC is often represented as a cycle because software development doesn’t end with deployment. The final phase involves maintaining the software, fixing any issues that arise, and adding new features as required. This cyclical process ensures that the software remains relevant and functional over time. The Role of DevOps in SDLC As a DevOps engineer, your primary role is to enhance the efficiency of the SDLC process. While SDLC lays out the roadmap for software development, DevOps focuses on streamlining and automating the workflow. By integrating DevOps practices, you can significantly improve the speed, quality, and reliability of software delivery. For example, during the design phase, a DevOps engineer might suggest tools for automated testing or continuous integration/continuous deployment (CI/CD) pipelines that align with the project's goals. During the deployment phase, DevOps practices ensure that the software is released in a smooth, controlled manner with minimal downtime.  Conclusion Understanding SDLC is crucial for anyone involved in software development, but it holds particular importance for DevOps engineers. By mastering SDLC, you can ensure that your projects are delivered on time, meet customer expectations, and maintain high-quality standards. As you progress in your DevOps career, keep in mind that your ultimate goal is to improve the efficiency and effectiveness of the software development process, benefiting both your organization and its customers.
