Hello.....sorry for the newbie question but I am trying to draw my support and resistance lines and was wondering how far back in time do I go. I can zoom in on the daily and weekly charts that could take me as far back as 1998! What is a good period of historical data to be able to mark in support and resistance lines. Thanks in advance
