NeuralFlex is an AI trading system for US stocks and crypto, run in public. Its live account trades virtual money on an Alpaca paper account, and anyone can watch equity, drawdown and open positions update every 30 seconds. Members see every position and time-stamped fill. The research log says how many ideas failed: 1,865 tested, none passed validation. Simulations are clearly labelled. Built to be measured, not to be believed. Not investment advice.
