Pieces by Yorben De Reuse
Your own charting platform, built by an agent, on your broker's data
I had a coding agent build a charting platform that runs on my own computer, reads my MT5 terminal and does a few things TradingView can't. The code is public on GitHub, so you can skip the groundwork and build the features you've always wanted, from footprint and TPO charts to your own DOM.
A safety check for the trading tool you built with AI
Building a trading or investing tool with a coding agent takes an evening, and checking what that tool can do with your account takes about one more. These are the nine questions I'd go through, starting with the key and ending with the off switch.
Spending limits for AI agents: soft, hard and signed
Card networks, payment platforms and fintechs have all announced ways to let an AI agent pay. They all set a budget, but they put it in very different places, and that place decides whether the limit holds.
Which brokers let AI trade your account, and how far each one goes
In 2026, broker after broker opened a door for AI assistants. Some let the AI look, some let it trade after you say yes, a few let it trade on its own. What matters most is where that yes is enforced.
My trading journal updates itself every night. Here is how I built it.
I asked an AI coding agent to build a private trading journal and performance dashboard from my MT5 history. It reads my trades, never touches an order, and rebuilds itself while I sleep.
How often should you rebalance? What the research says, and where AI helps
The research favours a rebalancing rule that needs daily attention; an AI assistant can supply the attention, as long as it never does the maths and never places the order.
Prompting Against the Machine: Using AI in Trading
How to prompt an AI about your own trading, whether you trade by hand, by rules, or by code it wrote for you.
