Artificial neural networks applied to the prediction of the gold price

Abstract:

Gold price prediction using an artificial neural network model (ANN) is proposed in this work. The objective of the model is to predict the daily closing prices in the London market, which are taken as reference prices for the Central Bank of Colombia. Different configurations of type feed-forward ANN are considered using the dollar index DXY, the SP500 index, the daily oil price series, and the daily gold price series, as inputs to the ANN model. A set of ANN structures are trained using the historical series of data, where one portion is used for training and the other portion is used for testing (prediction). The results show good performance of the model both in the analyzed historical period and the predictions, where the best structure includes the daily price series of gold, the DXY index and the SP500 index.
