Forex trading strategy. In fact, there is no real prediction involved in either system. If your model needs re-training after every datapoint, its probably not a very good model. I did some rough testing to try and infer the significance of the external parameters on the Return Ratio and came up with something like this: Or, cleaned up: You may think (as I did) that you should use the Parameter. In our framework above, what is Y? Def normalize(basis_X, basis_y, period basis_X_norm (basis_X - basis_an basis_d basis_y_norm (basis_y - basis_y_norm basis_y_normbasis_X_dex return basis_X_norm, basis_y_norm norm_period 375 basis_X_norm_test, basis_y_norm_test norm_period) basis_X_norm_train, basis_y_norm_train normalize(basis_X_train, basis_y_train, norm_period) regr_norm, basis_y_pred basis_y_norm_train, basis_X_norm_test, basis_y_norm_test) basis_y_pred basis_y_pred * Linear Regression with normalization Mean squared error:.05 Variance score. We now need to prepare the data in a format we like. We are going to create a prediction model that predicts future expected value of basis, where: basis Price of Stock Price of Future basis(t)S(t)F(t) Y(t) future expected value of basis Since this is a regression problem, we will evaluate the model on rmse. There seems to be a widely popular misconception at the moment, that ML is something that automagically works out of the box - you just need to throw data.

Lets create/modify some features again and try to improve our model. For this first iteration in our problem, we create a large number of features, using a mix of parameters. This provides you with realistic expectation of how your model is expected to perform on new and unseen data when you start trading live. Lets say you have data for a year and you use Jan-August to train and Sep-Dec to test your model, you might end up training over a very specific set of market conditions. This may be a cause of errors in your model; hence normalization is tricky and you have to figure what actually improves performance of your model(if at all). Your data could fall out of bounds of your normalization leading to model errors. Eventually our model may perform well for this set of training and test data, but there is no guarantee that it will predict well on new data. For example what might seem like an upward trending pattern explained well by a linear regression may turn out to be a small part of a larger random walk! Image: Faception, examples of biases and failures in algorithms abound, but even when not taken to extremes, ML is not something that just works on its own. Import seaborn c basis_X_rr gure(figsize(10,10) seaborn. A simplistic classification for potential routes could be something like "Impossible "Bad "Good or "Optimal.". The clients algorithmic trading specifications were simple: they wanted a Forex robot based on two indicators.
