Hi Ergo, Here's a "primer" on Zig Zags as I'm currently using them: <A HREF="http://www.investorshub.com/boards/read_msg.asp?message_id=278761" target="_new">http://www.investorshub.com/boards/read_msg.asp?message_id=278761</A> It shows the settings for the StockCharts.com service. I'm not trading more frequently (usually) than once per week, so I use the "weekly" data. Best regards, Tom
