London Seminar: Rob Carver: Heisenberg's Backtest
Huxley Building, Imperial College London, 180 Queen's Gate, South Kensington, London SW7 2AZ, London, GBPlease note that this event will take place IN PERSON on Friday, 6 March, 2026 in London at 6pm London time (1pm New York time).
In collaboration with Imperial College MathSoc!
Full title: Heisenberg's Backtest
Speaker: Rob Carver
Abstract: What is a backtest for? In fact, like electrons, backtests have two contradictory natures. Firstly, they tell how well a particular trading strategy would have done in the past. Secondly, they help you design a strategy that will perform well in the future. These are not the same thing. In this talk Rob discusses this problem and how to reconcile these two objectives.
Venue: Huxley Building, Imperial College London, 180 Queen's Gate, South Kensington, London SW7 2AZ

Full title: A Weekend with Robert Carver in London: Backtesting Properly
Speaker: Robert Carver
Training Agenda:
This workshop will run through the process required to construct backtests that provide realistic historic returns and provide the best chance of creating a strategy that will be profitable in the future. It is not about fancy ML or AI techniques, nor is it designed to give you a magic formula for making infinite money from trading. Instead it will focus on understanding:
- statistical significance
- optimisation
- the importance of robustness and how to achieve it
- avoiding the three different types of overfittingPre-requisites for workshop:
- Attendance at the talk: https://www.meetup.com/thalesians/events/312539371/
- Ability to use python / pandas ecosystem to the level of https://www.oreilly.com/library/view/python-for-finance/9781492024323/
- A laptop with a full Anaconda stackVenue: Huxley Building, Imperial College London, 180 Queen's Gate, South Kensington, London SW7 2AZ
