Investor journal #1: why I built DSMarketLearning

I'm starting this weekly series with something I'd been wanting to write for a while: why DSMarketLearning exists and what I hope it brings to whoever reads it.

Access became massive

Digital technology has undoubtedly made access to the stock market massive, putting the chance to learn and generate income over time within everyone's reach. Not that many years ago, investing was, in practice, something reserved for people with a trusted broker, significant capital, or a job close to the financial world. Today anyone with a phone can open an account, buy a fraction of a share, and access market data that only professionals used to see.

That's genuinely positive. But democratizing access isn't the same as democratizing the knowledge to use it well — and that's where I want to contribute something.

My learning curve was hard

In my experience, the learning curve was hard, with plenty of losses at the start. I'm a software engineer, so when I first got interested in markets I assumed, with a bit of technical arrogance, that understanding the numbers would be enough. It wasn't. I took real losses for reasons that, in hindsight, were avoidable: trading without really understanding what an indicator meant, buying on impulse when I saw something "already going up," having no idea how to think about a position's risk before opening it. None of that gets solved with more screens or more data; it gets solved by understanding the underlying mechanics before making a decision.

Why I built this site

With this site I want to help the community, mainly those who are just getting into this world, understand basic concepts and read indicators. To do that I combined my work as an engineer with what I learned following markets, and made two deliberate decisions:

  • A simple scanner, without too many complex indicators. It's easy to fill a dashboard with dozens of exotic indicators that impress but aren't understood. I preferred a limited set of signals — a score, price, P/E, PEG, market cap, volume, and target price — that lets you understand the mechanics of the markets before making a decision, instead of a wall of numbers without context.
  • Content that explains the "why," not just the "what." Hence this blog: articles that don't assume you already know what a PEG or an RSI is, written for someone starting exactly where I started.

Why it's worth reading this site

If you're just starting out, what you'll find here is exactly what would have saved me time and losses at the beginning: clear explanations of each indicator before you use it, a scanner that summarizes technical and fundamental signals into a single score instead of forcing you to interpret a dozen loose numbers, and articles designed to build your own judgment — not to tell you what to buy. You won't find promises of returns or "buy this now" signals; you'll find the same tools and explanations I wish I'd had when I started, so you understand the market's mechanics before risking your money.

What this site is and isn't

I want to be clear about this: this blog is educational and, under no circumstances, should be taken as investment advice. I share what I've learned and how I interpret certain indicators, but decisions about your money are yours, based on your own analysis and, where possible, the guidance of a registered financial advisor. My goal is for you to understand the mechanics before deciding — not to decide for you.

From here on, every week I'll share a bit of this experience: a concept that was hard for me to grasp, a mistake I made, or how I think about a market situation from this side of the code. Thanks for reading this far.
