Systems for Systematic Markets
Insider @ NXFD
We publish working notes – what we tested, what broke, what held up, and what we changed. Less hype, more process: robustness, risk controls, execution details, and disciplined iteration.

Execution Reality: Slippage, Fees, Funding, and Adverse Selection
In trading, slippage is one of the most underestimated execution risks. Execution is where most strategies go to die. In research, execution is often a parameter. In production, it’s the environment. The same signal can look stable in simulation and…

Why We Don’t Forecast (Much): Robustness > Predictions
Most trading content starts with a prediction. Ours usually starts with a constraint. Crypto spot and futures markets are noisy, reflexive, and regime-driven. The hard part isn’t producing a confident view – it’s building a system that survives when the…
