History tends to repeat itself. Economic expansions are followed by recessions. Bull markets are followed by bear markets. Where are we going in the future. This app makes a prediction of the future by looking for similar patterns in the past. You only need to define two parameters: pattern size (number of days) and number of historical patterns you want to search for. The outcome of these patterns are used to predict the future. You can download data for DJIA, Nasdaq, S&P 500, FTSE 100.
