Learning the dynamics of technical trading strategies
We use an adversarial expert based online learning algorithm to learn the optimal parameters required to maximise wealth trading zero-cost portfolio strategies. The learning algorithm is used to determine the dynamics of a large population of technical trading strategies that can survive historical back-testing as well as form an overall aggregated portfolio trading strategy from the set 最佳技术交易策略 of underlying trading strategies implemented on daily and intraday Johannesburg Stock Exchange data. The resulting population time-series are investigated using unsupervised learning for dimensionality reduction and visualisation. A key contribution is 最佳技术交易策略 that the overall aggregated trading strategies are tested for statistical arbitrage using a novel hypothesis test, on both daily sampled and intraday time-scales. The (low frequency) daily sampled strategies fail the arbitrage tests after costs, while the (high frequency) intraday sampled strategies are not falsified as statistical arbitrages after costs. The estimates of 最佳技术交易策略 trading strategy success, cost of trading and slippage are considered along with an offline benchmark 最佳技术交易策略 portfolio algorithm for performance comparison. In addition, the algorithms generalisation error is analysed by recovering a 最佳技术交易策略 最佳技术交易策略 probability of back-test overfitting estimate using a nonparametric procedure. The work aims to explore and better understand the interplay between different technical trading 最佳技术交易策略 strategies from a data-informed perspective.
