1. A computer method relating to real-time transforming at least one “data-feed” relating to historical time-relevant trading data relating to at least one tradable instrument, comprising: a) receiving, by at least one computer, historical time-relevant trading data relating to such at least one tradable instrument; b) calculating, by at least one computer, as at least one first calculation, at least one first time-relevant value representing historical collective desire to sell such at least one tradable instrument using such historical time-relevant trading data for at least one plurality of timeframes, wherein such at least one plurality of timeframes comprise discrete periods of time, each of substantially different time lengths than each other, from at least one minute to at least one year; c) calculating, by at least one computer, as at least one second calculation, at least one second time-relevant value representing historical collective desire to buy such at least one tradable instrument using such historical time-relevant trading data for such at least one plurality of timeframes; d) comparing, by at least one computer, such historical collective desire to sell such at least one tradable instrument to such historical collective desire to buy such at least one tradable instrument to make a first determining of at least one “greater-lesser relationship” between such historical collective desire to buy and such historical collective desire to sell for at least one timeframe of such at least one plurality of timeframes; e) comparing, by at least one computer, in at least one prior timeframe, such historical collective desire to sell such at least one tradable instrument to such historical collective desire to buy such at least one tradable instrument to make a second determining of at least one “greater-lesser relationship” between such historical collective desire to buy and such historical collective desire to sell for at least one timeframe of such at least one plurality of timeframes; f) comparing, by at least one computer, such first determining with such second determining g) identifying, by at least one computer, any reversal of such “greater-lesser relationship” between such first determining and such second determining; h) creating, by at least one computer, at least one set of buy/sell indicators for such at least one tradable instrument for each such indentified reversal; i) creating, by at least one computer, at least one first graphical representation of such at least one first time-relevant value for such at least one timeframe; j) creating, by at least one computer, at least one second graphical representation of such at least one second time-relevant value for such at least one timeframe; k) wherein such at least one first graphical representation and such at least one second graphical representation are presented, by at least one computer, jointly in at least one comparative analysis chart; l) wherein such real-time transforming at least one “data-feed” to provide such graphical representations is accomplished; m) comparing, by at least one computer, such historical collective desire to sell such at least one tradable instrument to such historical collective desire to buy such at least one tradable instrument to determine at least one “greater-lesser relationship” for at least one plurality of such periods of time of such at least one plurality of timeframes; n) presenting, by at least one computer, results of such comparison for each of such at least one plurality of such periods of time for such at least one plurality of timeframes; and o) presenting, by at least one computer, at least one notice when such at least one reversal of such “greater-lesser relationship” occurs in at least two such discrete periods of time.
