One dev built an algotrading bot using multiple AI models with Cursor
A developer shared their experience building an automated stock trading program using the Cursor code editor alongside several AI language models. It's a hands-on example of a solo builder tackling complex financial software with AI tools alone. The post highlights both the potential and the limits of this approach.
The post describes using Cursor — a code editor with built-in AI assistance — and switching between multiple large language models (LLMs) to build an algorithmic trading bot. An algorithmic trading bot is a program that automatically buys and sells stocks or crypto based on preset rules, without human intervention.
The original post does not share specific profit figures or detailed strategy rules, so the actual trading performance is unknown. Still, the case is interesting for solo developers because it shows that complex financial software, which once required a specialized team, can now be prototyped by one person using AI coding tools. Anyone considering a similar project should independently verify the code and apply proper risk management before using real money.
Key points
- Built an automated trading program solo using Cursor and multiple AI models.
- An algorithmic trading bot executes buy/sell orders automatically based on coded rules — no human needed in the moment.
- Switching between several LLMs during development can help cover different coding tasks.
- No verified profit numbers were shared; real-money use requires independent testing and risk controls.
