On this BST live show, Rob Carver from systematicmoney.org joins us to discuss “3 ways traders kill trading strategies”. Here are just some of the topics you’ll discover in this episode:

  • What can go wrong with strategies in live trading,
  • The impact of model complexity on prediction error, (and are simple models really better than more complicated ones - the answer may surprise you!),
  • The dangers of overstated backtest performance,
  • The impact of historic costs on backtest results,
  • The 3 types of overfitting, including 1 that most traders don’t even realise they’re doing, and how to reduce their impact on your trading models,
  • Strategy robustness and letting data define complexity,
  • The overfitting "levels of sin",
  • Correcting for the "multiple testing problem",
  • Fitting metrics, sample size, data quality, prediction error and much more.
