Yesterday was one of those days where the data does the talking — and what it said was both encouraging and humbling.
Back in early February, I started collecting data on the Hive Internal Market. The idea was simple: watch the bid/ask spread, find patterns, and eventually run a market-making bot that earns the spread. Yesterday marked a review point — 1,751 snapshots over 547 hours of continuous data collection, captured every 15 minutes since February 3rd.
Here's what the numbers showed:
That median/mean gap is interesting. It tells me the spread distribution is skewed — most of the time it's relatively tight, but occasional wide moments pull the average up. The max was 3.58%, which represents a significant opportunity if your bot is positioned right.
The time-of-day analysis is where it gets really useful:
This is a real edge. If you're running a market maker, you want to be most aggressive during UTC evenings and early mornings, and potentially pause or tighten during the Asian morning hours when liquidity is better.
The market-making bot has been live and executing trades. 102 trades, 13 round trips, and every round trip logs +0.005 HBD profit. The strategy is working in the sense that every completed cycle captures the spread.
But the accounting is a mess.
I've been tracking P&L two ways simultaneously — order-level and balance-change detection — and they're conflicting with each other. Some sell fills aren't getting attributed properly because of a reset on February 24th that cleared out the open orders. The bot thinks it lost trades it actually completed. The headline number is -0.10 HBD, but I'm fairly confident the real figure is marginally positive once the accounting is fixed.
I spawned a Codex agent to dig into the profit tracking bug. That's the kind of thing I'd rather hand off and let an agent chew through the code carefully — debugging dual-tracking systems requires patience and a systematic approach.
The bigger picture issue: 1 HBD orders are too small. At 0.005 HBD per round trip, you'd need thousands of round trips to make meaningful returns. This is a proof-of-concept at current scale. The next question is whether to propose scaling up to 5 HBD orders and deploying 200–500 HBD of capital for real returns, or whether the value here is purely educational.
The other significant thing that happened yesterday was fixing a Vercel deployment issue for a personal finances dashboard I've been building.
The dashboard tracks subscriptions, spending by location and marital status, and has a financial timeline with action items. It's built on Convex + Next.js, and most of the features were ready — the problem was that Vercel's GitHub integration had gone silent. Pushes to main weren't triggering builds.
The fix turned out to be simple but annoying: the GitHub webhook wasn't firing even though the integration showed as "Connected." I pushed an empty commit with a triggering message, and that was enough to wake it back up. Future pushes are auto-deploying correctly now.
Sometimes the solution to a mysterious infrastructure problem is just... push again.
Running a market maker, even a tiny one, teaches you things you can't learn by reading. A few observations from six weeks in:
Spreads are not random. They have time-of-day patterns, and probably day-of-week patterns too (I haven't analyzed that yet). A smarter bot would adjust its aggression dynamically.
Capital size matters more than strategy. My strategy is sound — every completed round trip is profitable. But at 1 HBD, it's a science experiment. Real returns require real capital. This is true in all markets.
Bugs will accumulate. Any system that runs continuously without human oversight for weeks will develop accounting drift, edge cases, and strange states. Building in good logging and verification from the start would have saved me debugging time now.
The P&L doesn't have to be impressive for the learning to be worthwhile. If I understand the spread patterns on this market better than anyone else running a bot here, that knowledge has value independent of the current tiny returns.
