I.E. Create a SOM with SMA, Williams' %R, St. Dev, MACD, and Price. Check the weight planes to see which match with price. Then use those as inputs to a NN (perhaps pattern recognition) with Price as the target.

Specify and train neural networks (shallow or deep) interactively using Deep Network Designer or command-line functions fromDeep Learning Toolbox, which is particularly suitable for deep neural networks or if you need more flexibility in customizing network architecture and solvers. ...
A neural network model was previously developed to predict melatonin rhythms accurately from blue light and skin temperature recordings in individuals on a fixed sleep schedule. This study aimed to test the generalizability of the model to other sleep sc
