Ask how models are trained, how often they refresh, which features dominate decisions, and where guardrails constrain behavior. Request documentation on backtests, including transaction costs and delisted assets. A thoughtful provider welcomes scrutiny, because robust processes survive daylight and improve through specific, informed feedback.
Numbers should reconcile across time frames and not change when you refresh the page. Beware cherry picked benchmarks, tiny sample periods, and unclear compounding conventions. Recreate simple calculations yourself, and treat resistance to verification as an early signal that promises outrun discipline.
Confirm account segregation, role based access, and encryption practices. Understand which broker actually holds assets, who initiates trades, and how to revoke permissions instantly. Test the exit path first, because fast, predictable off ramps matter most during stress, outages, or abrupt disagreements about risk.
