In his second book, Automated Stock Trading Systems, Bensdorp details a non-correlated, multi-system approach you can understand and build to suit yourself. Using historical price action to develop statistical edges, his combined, automated systems have been shown to deliver simulated consistent high double-digit returns with very low draw downs for the last 24 years, no matter what the market indices have done. By following his approach, traders can achieve reliable, superlative returns without excessive risk.
