### How do I create & train a neural net to predict a stock closing price at T+5min using OHLC and other data?

I'm trying to create a neural network and train it to test predictability of short term stock price movements. I've collated a 1-min open, high, low, closing and volume dataset for a particular stock....

### Creating a prediction/distribution based on several years of data

So I have several years of data from a survey. For each year I've used FindDistribution and Predict to see if I can fit the data. Here's one example Where I used FindDistribution to get ...
