It is what happens to your edge when everyone else has one too. https://vizanix.tech/en/blog/ai-strategy-development/ https://vizanix.tech/en/blog/ai-strategy-development/ Sat, 29 Aug 2026 00:00:00 +0000 Markets and AI Not “ask a model what to buy”. A working ML strategy is a data pipeline, a labelling decision, honest validation and an expected-value gate — the model is the smallest part. https://vizanix.tech/en/blog/ai-agents-market-structure/ https://vizanix.tech/en/blog/ai-agents-market-structure/ Sat, 29 Aug 2026 00:00:00 +0000 Markets and AI When most participants run similar models on similar data, they stop being independent actors. That correlation is invisible in normal conditions and decisive in bad ones. https://vizanix.tech/en/blog/llm-in-trading/ https://vizanix.tech/en/blog/llm-in-trading/ Sat, 29 Aug 2026 00:00:00 +0000 Markets and AI An LLM is excellent at turning unstructured text into structure and terrible at being the thing that decides to send an order. Those are different jobs. https://vizanix.tech/en/blog/machine-learning-alpha-decay/ https://vizanix.tech/en/blog/machine-learning-alpha-decay/ Sat, 29 Aug 2026 00:00:00 +0000 Markets and AI Every edge has a half-life. What changed is that the tooling to find and copy an edge got cheap, so the half-life got shorter — and planning for that is part of the design. https://vizanix.tech/en/blog/feature-engineering-vs-deep-learning/ https://vizanix.tech/en/blog/feature-engineering-vs-deep-learning/ Sat, 29 Aug 2026 00:00:00 +0000 Markets and AI Deep learning dominates domains with enormous data and high signal-to-noise. Market prediction is the opposite of both, which is why boosted trees on hand-built features keep winning. https://vizanix.tech/en/blog/model-drift/ https://vizanix.tech/en/blog/model-drift/ Sat, 29 Aug 2026 00:00:00 +0000 Markets and AI Strategies rarely fail loudly. They degrade, and the equity curve is the last place it becomes obvious. Detecting it earlier is a monitoring problem with a known solution. https://vizanix.tech/en/blog/reinforcement-learning-trading/ https://vizanix.tech/en/blog/reinforcement-learning-trading/ Sat, 29 Aug 2026 00:00:00 +0000 Markets and AI RL is the most requested and least delivered approach in retail quant.

On market data they usually are not, which is why most trading ensembles are one model with extra latency. https://vizanix.tech/en/blog/why-not-buy-a-bot/ https://vizanix.tech/en/blog/why-not-buy-a-bot/ Sun, 30 Aug 2026 00:00:00 +0000 Why and when A marketplace bot with a beautiful backtest is not lying to you exactly.

It does not tell you whether the machine that produced it is working — and by the time P&L reveals a broken bot, it has been broken for a while. https://vizanix.tech/en/blog/backtesting-vs-paper-trading/ https://vizanix.tech/en/blog/backtesting-vs-paper-trading/ Fri, 28 Aug 2026 00:00:00 +0000 Research and validation A backtest tests a hypothesis about the market. Paper trading tests your software against reality. Skipping either one means shipping on an untested assumption. https://vizanix.tech/en/blog/lookahead-leaks/ https://vizanix.tech/en/blog/lookahead-leaks/ Fri, 28 Aug 2026 00:00:00 +0000 Research and validation Every leaked bit of future information makes a backtest look better. That is why leaks are so hard to notice — the evidence of the bug is a result you were hoping for. https://vizanix.tech/en/blog/latency-and-slippage/ https://vizanix.tech/en/blog/latency-and-slippage/ Fri, 28 Aug 2026 00:00:00 +0000 Research and validation Latency only matters in proportion to how fast your edge decays.
