Robert Carver joins The Sophron® Network to explain what changes, and what does not, when you go from running a $5 billion fixed income book at a systematic hedge fund to trading your own futures portfolio from home. His system covers roughly 250 futures markets, runs fully automatically, and needs about five minutes of his attention a month. This conversation is about what those five minutes are actually spent on, and about the parts of systematic trading that rarely get discussed: contract rolls, reconciliation, broker APIs and the discipline of not intervening. Robert Carver is an independent systematic trader, investor and writer, and the author of Systematic Trading, Smart Portfolios, Leveraged Trading and Advanced Futures Trading Strategies, with a fifth book, The Art and Science of Trading, due in December 2026. He trades his own portfolio using pysystemtrade, the open source Python framework he built and publishes alongside his live positions, and is a visiting lecturer at Queen Mary, University of London. He previously spent seven years at AHL, part of Man Group, most recently as Head of Fixed Income, where he managed a $5 billion portfolio across roughly $1.5 billion of annualized active risk. Earlier he was a research manager at the Centre for Economic Policy Research and an exotic derivatives trader at Barclays Capital. We examine why 999,000 of his million lines of Python have nothing to do with signals, why he argues 99% of a trader's success is implementation, and why he refuses to retire strategies that appear to have stopped working. We also discuss capacity and execution at different account sizes, regime models, AI in research, the architecture of pysystemtrade, broker reconciliation, counterparty risk, and what a systematic fund actually worried about in 2008.
