Here, “S” represents the support levels, “R” the resistance levels and “P” the pivot point. High, low and close are represented by the “H”, “L” and “C” respectively. Note that the high, low and close in 24-hour markets(like the forex market)are often calculated using New York closing time (4pm EST) on a 24-hour cycle. Limited markets (like the NYSE and Nasdaz ) simply use the high, low and close from the day’s standard trading hours.
