💸 Why Retail Traders Struggle in the Stock Market: The Charges No One Talks About

Most beginners enter the stock market dreaming of financial freedom. They follow YouTube gurus, try "proven" intraday strategies, and set out to double their capital.

But soon, reality hits — not because they are wrong in analysis, but because the game is rigged with charges that no one talks about.

🧾 The Hidden Cost of Trading: Charges Explained

Let’s say you do a basic intraday Nifty options trade:

• Buy 1 lot (75 qty) at ₹100
• Sell at ₹105
• You make ₹5 x 75 = ₹375 gross profit

Now the charges kick in:

Charge Type	Approx. Amount
Brokerage (₹20 x 2)	₹40
STT (on Sell)	₹19.69
Exchange Transaction Charges	₹5.62
GST (18% on ₹45.62)	₹8.21
SEBI Charges	₹0.15
Stamp Duty (Buy side only)	₹4.50
Total Charges	₹78.17
Net Profit	₹296.83

🔻 So, even when you're right, you lose 20%+ of your profits to charges.

What is the difference between NgZone and CDR in Angular

 NgZone vs ChangeDetectorRef (CDR) in Angular

Both NgZone and ChangeDetectorRef (CDR) help with change detection, but they serve different purposes.

---

🔹 NgZone

NgZone is a service that controls how Angular detects changes globally across the application. It helps manage execution inside or outside Angular's change detection system.

✅ When to Use NgZone?

1. Running non-Angular events (like setTimeout, WebSockets, or third-party libraries) inside change detection.
2. Skipping change detection for performance (e.g., animations, timers).

🔹 Key Methods:

• run(callback) → Forces Angular to detect changes.
• runOutsideAngular(callback) → Runs code outside change detection (for performance).

Example:

Difference between .some(), .includes(), and .findIndex()

Let’s compare .some(), .includes(), and .findIndex() to see why .some() is the best choice in this case.

---

1. Why Not .includes()?

How .includes() Works

• .includes(value) only works for exact matches in an array.

• It checks if the array contains the exact string or number.

Why It Won’t Work Here

Your case needs partial matching (window.location.hostname.includes(host)), but .includes() only checks for exact matches.

🔴 Example: Doesn't Work for Partial Matching

const hosts = ["localhost", "127.0.0.1"];

const isLocal = hosts.includes(window.location.hostname);

console.log(isLocal);

❌ This only works if window.location.hostname is exactly "localhost" or "127.0.0.1", but it fails if the hostname is "localhost:4200" (which is common in Angular development).

How to remember password in FortiClient VPN?

In Windows, to save your VPN password using the Registry Editor:

1. Open the Registry Editor:

   • Press Win + R, type regedit, and press Enter.

2. Navigate to:

   • HKEY_CURRENT_USER\SOFTWARE\Fortinet\FortiClient\Sslvpn\Tunnels\<VPN_NAME>

3. Find the show_remember_password entry:

   • Look for the show_remember_password entry under the <VPN_NAME> tunnel configuration.

4. Change the value:

   • Set the value of show_remember_password from 0 to 1.

5. Save your changes:

   • By changing this value, you will be able to save your password for later use.

---

Replace <VPN_NAME> with the actual name of your VPN configuration. This change will allow your FortiClient to remember your password for future sessions.

Docker vs Kubernetes

 Docker and Kubernetes are both essential tools in the container ecosystem, but they serve different purposes and are often used together in modern software development and deployment. Here’s a breakdown of each and a comparison of their functionalities and roles.

What is Docker?

Docker is a platform for developing, shipping, and running applications in containers. Containers are lightweight, portable units that package application code along with all its dependencies, making it easy to run applications consistently across different environments.

Key Docker components:

• Docker Engine: The runtime that builds, runs, and manages containers on a host.
• Docker Images: Templates used to create containers; they contain application code and dependencies.
• Docker Containers: Running instances of Docker images that provide isolated environments for applications.
• Docker Compose: A tool for defining and running multi-container Docker applications, useful for developing and testing services locally.

What is Kubernetes?

Kubernetes is a container orchestration platform designed to manage, scale, and deploy containerized applications across clusters of machines. While Docker handles individual containers, Kubernetes automates the deployment, scaling, and management of containerized applications across multiple hosts, ensuring high availability and scalability.

Key Kubernetes components:

• Cluster: A collection of nodes (hosts) where Kubernetes manages containers.
• Pods: The smallest deployable units in Kubernetes, typically a single container or a group of closely related containers.
• Nodes: The physical or virtual machines that host the containers.
• Control Plane: Manages the cluster, schedules workloads, and monitors the cluster’s state.
• Services: Provide load balancing and service discovery for pods, ensuring that applications remain accessible.

Docker vs. Kubernetes

What is Kubernetes?

 Kubernetes (often abbreviated as "K8s") is an open-source platform designed for managing containerized applications in a distributed environment. Originally developed by Google, it is now maintained by the Cloud Native Computing Foundation (CNCF). Kubernetes automates deployment, scaling, and operations of application containers across clusters of hosts, providing a container-centric infrastructure.

Key Components of Kubernetes

1. Cluster: A Kubernetes cluster is a set of nodes (machines) that run containerized applications. It consists of at least one control plane and several worker nodes.

2. Control Plane: The control plane manages the Kubernetes cluster and coordinates its activities. Key components include:

   • API Server: The primary management point, where users, other components, and external tools communicate with Kubernetes.
   • etcd: A key-value store that maintains the cluster’s state, configuration, and metadata.
   • Controller Manager: Monitors the cluster’s desired state and ensures it matches the actual state, handling tasks like node management, replication, and endpoint management.
   • Scheduler: Allocates containers to available nodes based on resource requirements and constraints.
