What are you trying to predict? It however doesnt take into account fees/transaction costs/available trading volumes/stops etc. This is available to you during a backtest but wont be available when you run your model live, making your model useless.
Install it using pip install -U scikit-learn. Remember what we actually wanted from our strategy? Before we begin, a sample ML problem setup looks like below. It might be better to try a walk forward rolling validation train over Jan-Feb, validate over March, re-train over Apr-May, validate over June and. An example would be where a stock may trade on two separate markets for two different prices and the difference in price can be captured by selling the higher-priced stock and buying the lower priced stock. You may also need to clean your data for dividends, stock splits, rolls etc. Ensemble Learning Ensemble Learning Some models may work well in prediction certain scenarios and other in prediction other scenarios. The systems used by these firms and individual are based on weak correlations uncovered by a quantitative analyst. This was accomplished by implementing Long Short-Term Memory Units, which are a sophisticated generalization of a Recurrent Neural Network. Remember once you do check performance on test data dont go back and try to optimise your model further. This means you cannot use Y as a feature in your predictive model.
