Also, the graduations can be changed. The previous graduations of 38.2/61.8 are changed to 33/66, but the user can alter. The indicator can be overlaid upon a normal Volumes window, providing emphasis, if you do not show the below average bars. Two added text labels show the current bar volume and its percentage of the average bar volume for the selected averaging period. - Traderathome --------------------------------------------- -----------------------*/ #property indicator_separate_window #property indicator_buffers 5 #property indicator_color1 Blue // Volumes below average #property indicator_color2 Gold // Volumes over average by 0% to 38.2% #property indicator_color3 LimeGreen // Volumes over average by 38.2% to 61.8% #property indicator_color4 Crimson // Volumes over average by 61.8% to 100% #property indicator_color5 WhiteSmoke // Volumes greater than 100% over average #property indicator_width1 2 #property indicator_width2 2 #property indicator_width3 2 #property indicator_width4 2 #property indicator_width5 2 //---- External Inputs extern int VolumePeriod = 10; extern bool ShowBelowAvgVolumes = true; extern string Need_2_numbers_dividing_range = "0-100 into 3 parts (33&66, 25&50 etc)"; extern double Enter_Number_1 = 33; extern double Enter_Number_2 = 66; extern bool Display_volume_text_labels?
