Given a series of intraday (i.e. transaction based) price data, we want to decompose the price change into three components (yi = Pti - Pti-1 = Ai*Di*Si). The three components are price change indicator (A), direction of price movement (D) and the size of price change in ticks (S) if the change occurs.
