Quick summary
At 18, with money saved from freelance work, I opened a commodity futures account on MCX. The early trades went fine. Then I lost most of it in a week. This is what I learned — about markets, risk, and why expensive lessons are the ones that actually stick.
I was 18. Engineering first year. Pune.
I had some money saved from small freelance projects. Not a lot. But enough to feel like I was doing okay for my age.
Someone in college was talking about commodity futures. Crude oil on MCX. He wasn't an expert — he was just confident, which at 18 sounds like the same thing. I listened. I read some things online. I watched a few YouTube videos. And then I opened a trading account.
I was going to be smart about this.
The early trades went fine
That's the dangerous part. When you start and things go okay, your brain records it as confirmation that you know what you're doing. You don't. You got lucky. But you don't know that yet.
I made a few small wins. I got more confident. I started sizing up my positions. The wins felt good. The losses felt temporary.
I had a theory about where crude prices were going. I had read about supply, demand, geopolitical stuff. I had opinions. I thought my opinions were actually analysis.
They weren't.
Then the market did what markets do
I had a position open. Crude oil. I was betting it would go up. It went the other direction instead. Fast.
I watched the losses climb. I didn't close the trade. I kept thinking it would reverse. That's the specific version of denial that costs the most money in trading. You hold. You hope. The number keeps getting worse.
By the time I closed it, a significant part of what I had put in was gone. Real money. The kind that feels very different when you're 18 and earned it yourself.
The loss isn't just the money. It's the version of yourself that was sure they understood something. That version doesn't come back.
What I actually learned
Not the stuff people say in these posts — "I learned about risk management" and "I learned discipline." That's true but it's surface. Here's what actually changed in me:
Confidence and competence are not the same thing. I had high confidence and low competence. That combination is dangerous in trading. It's also dangerous in building companies. I've watched early-stage founders make the same mistake — they mistake their enthusiasm for their product with actual customer demand. It's the same feeling. Different context.
Losses hurt more than wins feel good. This is documented in behavioral economics but you don't really understand it until you live it. Losing money I had actually worked for felt about three times worse than the wins felt good. That asymmetry changed how I think about downside risk in everything I do now.
The "I'll hold and wait for it to reverse" instinct will destroy you. In trading it's a money problem. In business it's a time problem. I've had projects I held onto for too long when the signs were already there. The same psychology. The hope that something will reverse if you just wait a little longer.
Markets don't know you exist. This sounds obvious but it hits different at 18. The market doesn't know I was smart at college. It doesn't care about my theory. It has no interest in validating my analysis. It just does what it does. That kind of feedback is brutal and also clarifying. It's the only environment where the results are this honest.
The part I don't usually say out loud
I went quiet about it for a while. Didn't tell many people. There's something specifically embarrassing about a financial loss when you're young and thought you were clever. It felt like evidence that I wasn't as sharp as I thought.
I eventually told a few people. One of them said something I've kept: "The ones who lose money early and keep going usually end up better at this than the ones who get lucky first."
I don't know if that's statistically true. But it matched how I felt. I came out of it more careful. More honest about what I don't know. Less in love with my own theories.
Where it shows up now
I run an AI company. We build systems that handle real business workflows. When a client wants to automate something, I have to give them an honest picture of what will work and what might not.
The 18-year-old version of me would have oversold it. Would have been confident in a way that wasn't grounded. Would have said yes to things I wasn't sure about because I wanted to look like I knew.
The version that blew up that trading account is more careful. Not scared — careful. There's a difference. I still move fast. I still take risks. But I've gotten better at knowing which risks I actually understand and which ones I'm just hoping work out.
The market taught me that. In the most direct way it could.
Would I do it again
Yeah. I would.
Not because losing money is good. But because some lessons don't stick until they cost you something. Reading about risk tolerance is not the same as losing money and feeling that specific sick feeling in your stomach.
The expensive lessons are the ones you actually remember.
