Hello All,
I was googling to get help in drawing the S/R lines & got this code which draws 2 lines in real time(making a zone instead of a line). The upper reistance line and lower support line matches hik's lie here. Hope it will help.
To hik:-have you any idea about the zones in relation to the line we are discussing?
cheers
