Point-and-figure charting has been a primary tool of day traders for many years. Using the minimum price movement as the box size and a 3-box reversal, many traders will keep a continuous, although lengthy, chart of day-to-day price movement. Buy and sell signals can be taken in the standard manner, but day traders are most likely to use these charts for identifying countertrend support and resistance levels. Intraday point-and-figure, as well as moving averages, often show frequent changes of direction before a new buy or Sell signal occurs, even when the minimum box size is used. Trend methods are best applied to short-term overnight positions in which the size of the move is much larger.
