Notes:

Follow my video blog Using WEKA, TA-Lib, and A.I. to estimate stock price trends

Combining the results from 15 different classification models for SP100 and 500 related ETFs - the results say we should expect continued "uptudiness" .Why? inverse (bearish) ETFs are in a cash position. While most bullish related ETFs are in a stock position.

The bullish/bearishness indicator is for the general market. So while an inverse type ETF may show a "go to stock" high percentage I look at this as a sell the market call. And vice versa if an inverse ETF has a high percentage in "go to cash" then it indicates a general market move to the upside.

Models: Best Moving Average, Double Moving Average, Triple Moving Average, MACD, RSI, MACD & RSI, Bollinger Bands, CCI, Derivative Oscillator, Stochastic, Double Stochastic, Ultimate Oscillator and Percentage Change Moving Average.

Attributes are mostly based on cross-overs.
Expected results used either a 3 or 4 day look-ahead.
All intervals for the models are optimized based on the best return for the past 8 months.

Was cash/stocks were models position at previous day.

To cash/stocks models expected next day position.
