Latest / Solopreneur Sessions with Fexingo: One-Person Businesses, Freelancing, and Independent Work / How One Solopreneur Built a Business on a Single Market Anomaly
Transcript
- Lucas: So there's this solo trader in Rotterdam who made over one hundred thousand euros last year off a quirk in the European carbon market. And the best part? He only worked on it about an hour a week. Luna: An hour a week? That sounds like the dream, but also kind of suspicious. What was the quirk? Lucas: So the European Union Emissions Trading System, the EU ETS, is this cap and trade market for carbon allowances. Companies need to hold these permits to cover their emissions, and they trade them like any commodity. But there's a settlement timing mismatch between the main exchange and the secondary market, and it creates a tiny price gap that persists for minutes at a time. Luna: So he was basically arbitraging the gap. But why didn't bigger firms snap that up? Lucas: That's the interesting part. The spreads are so small, like a few cents per permit, and the window is so short that most institutional players think it's not worth the infrastructure cost. But he built a simple script that monitors live prices and executes trades automatically when the gap widens beyond a certain threshold. Luna: So he automated the whole thing. How did he even stumble onto that? Lucas: He was originally a data analyst, and he was just messing around with public market data on weekends. He noticed the pattern on a chart, tested it for a few months, and then coded the bot. Now it runs on a small server, and he just checks in once a week to review performance and tweak parameters. Luna: That's the kind of side project that actually scales. But isn't there a risk that the gap closes once more people catch on? Lucas: That's a real risk, and he knows it. He's actually diversified into a couple of other energy markets now, but the carbon one is still his bread and butter. The thing is, these anomalies can persist for years because they're structural, not just a temporary glitch. Luna: Structural how? Lucas: Different trading hours, different clearing mechanisms, and just the fact that a lot of participants in this market are big industrial companies who aren't optimizing every cent. They're not running high-frequency trading bots; they're buying permits to comply with regulations. Luna: So he's essentially providing liquidity and getting paid for it. That's a pretty elegant business model. Lucas: Exactly. And it's a great example of a solopreneur finding an edge that bigger players overlook. But there's also a cautionary note here. He had to be careful about the regulatory side, because algorithmic trading in European markets is tightly monitored. Luna: Right, you can't just set up a bot and let it rip. What did he have to do to stay compliant? Lucas: He had to register as a trading entity, get a legal entity identifier, and implement some risk controls, like a kill switch that stops trading if something goes wrong. He also keeps detailed logs of every trade, which is a huge advantage if regulators ever ask questions. Luna: So it's not just 'set and forget.' There's real infrastructure behind it. But the payoff is that he's turned a market inefficiency into a sustainable income stream. Lucas: And that's the broader lesson for any solopreneur. You don't need to invent a brand new product. Sometimes the biggest opportunities are in the cracks of existing systems, where the friction is just high enough that bigger players don't bother. Luna: That's a great point. But let me play devil's advocate. Isn't this just a form of arbitrage that doesn't really add value to the world? Lucas: That's a fair question. In this case, I'd argue he's actually helping the carbon market function more efficiently. By taking advantage of the gap, he's essentially doing the work of aligning prices, which makes the market healthier overall. Luna: So it's a win-win. And he's doing it on his own terms, without a team or a big office. Lucas: Yeah, and that's the kind of solopreneur story we love to dig into. It's not about getting rich quick; it's about finding a niche, building a system, and letting it work. Luna: And it's a reminder that you don't need to follow the crowd. The next big opportunity might be in a corner of the market nobody else is looking at. Lucas: Totally. And on that note, we should mention that we keep this show free and ad-free because we believe these conversations should be accessible to anyone who's curious. If you've found some value in what we do, you can support that choice at buy me a coffee dot com slash fexingo. Luna: Yeah, it's a small way to keep the lights on, but it means a lot to us. And we're grateful for anyone who does. Lucas: So back to that Rotterdam trader. He's now looking at expanding into renewable energy certificates. There's a similar kind of mismatch there between the spot market and futures. Luna: That's smart. He's a proven pattern, so why not apply it to other markets? But I wonder, is this approach replicable for someone without a coding background? Lucas: That's a good question. A lot of these anomalies can be spotted with just spreadsheet analysis, and there are no-code tools that can automate trades. The hard part isn't the code; it's the discipline to test an idea and the patience to let it compound. Luna: So the real skill is not technical, it's mental. You have to be willing to sit there and watch the market do nothing for weeks before you see a pattern. Lucas: Exactly. And that's true for a lot of solopreneur ventures. The breakthrough moment often comes after a long period of just observing and learning. Luna: That's a good note to end on. Thanks for joining us on this episode, and we'll see you next time.
