Quote from kut2k2:
Sorry but you're completely wrong. Regarding astrology, dates and times are part of price data and volume data (how could they not be? we're talking about time series afterall). But locations have nothing to do with prices or volumes.
How you made the leap to mathematics and statistics is a complete non sequitur, but for the record: math and stat are not data, they are methods of data analysis, and I clearly said "method" in my definition.
Your definition of TA is wrong because (a) there is such a thing as discretionary (aka intuitive) TA and (b) I've never tried to predict price data in my life, yet I've developed a very successful TA-based trading strategy.
