Point and figure charts represent price movements using columns of X's and O's without a time component. Each box represents a specific price change threshold. Various box size settings like percentage or ATR scaling filter out small price fluctuations. Trends are identified by successive X or O columns, with reversals requiring a price move of the reversal amount. Support and resistance levels appear as horizontal rows. A 45-degree trendline can also be drawn. Price targets are estimated using vertical or horizontal box counts.
