AI

Every AI session starts with a blank slate. The context window fills up. The session resets. Everything you built together — context, decisions, in-progress work — is gone. Unless you designed around it. The Wrong Way to Handle Session Resets The instinct is to manually copy-paste summaries. Or clear files and reload them. Or re-explain everything at the start of each conversation. That doesn’t scale. Manual handoffs miss things. They compress context incorrectly. And they put the cognitive burden on you — the human — instead of the system. ...

I lost five years trading on instinct. Here’s what I should have understood from the start. I spent five years in crypto markets using the same method. Look at charts. Get a feeling. Place an order. Sometimes right. Sometimes wrong. Long term — always losing. It took me years to understand: it wasn’t bad luck. The method itself was unwinnable. Where Quant Trading Came From Quantitative trading isn’t new. In the 1980s, Wall Street started replacing human judgment with mathematical models. James Simons’ Medallion Fund ran from 1988 to 2018 with a 66% annualized return. Thirty years. Never a losing year. Not built on tips or instincts — built on mathematics. ...

Hard lessons from months of building with AI — what nobody tells you before you start. AI didn’t make building my quant system easy. It made it possible. Those are different things. Here are the 10 mistakes I made — and kept making — until I learned better. 1. Long Conversations Break Down AI has a memory limit. The longer the conversation, the more it forgets. You think it remembers your system architecture from 30 messages ago. It doesn’t. It starts giving advice that contradicts what it said earlier — and you don’t realize why. ...

From knowing nothing to running a live quant system — the tools that got me there. January 2026. I started building a quant trading system. Couldn’t write a single line of code. My first move wasn’t to learn programming. It was to find an AI that could write it for me. First Stop: A Basic Chatbot I started with a basic Chinese AI assistant. Low barrier, good Chinese, answered everything. I asked how to build a quant system and got a response that sounded complete and logical. ...

Every mistake I made building an AI quant system from scratch — so you don’t have to. January 20, 2026. I started from zero. Couldn’t write a single line of code. I just knew one thing: I was done letting humanity make my trading decisions. Step 1: The Server Asked AI where to start. Chose Google Cloud, Singapore region. Bought an instance. Opened ports. Set up SSH. The first time I connected from my phone, I felt like I’d come a long way. ...

Five years of crypto losses. One decision to change everything. Bitcoin at $5,000–$6,000. I put money in. Went straight to 100x leverage. Days later, gone. I came back. In two nights, my account went from $2,000 to over $100,000. Bitcoin moving from $22k to $30k. High leverage. Perfect timing. I thought I finally understood the market. Then, over the next few days — almost all of it, gone. What followed was five years of something worse than losing everything at once. ...
