hahahaa!!!!! LOL ... maybe old, but certainly not dumb! So those are "old" terms, eh .. I usually like "old school" stuff.
Hey Jim ... That is how the Moving Average moves Actually, they move because the days move. A simple moving average is calculated by taking the average of the stock prices over the past P-days (in your case, P=27). Do you then do additional stuff by subtracting the price of the first day in the series .. maybe to make an oscillator around a zero-line ??
