standard deviation
Hello, i know how to do the calculation of sq root etc to find the standard deviation , however not understand how to apply it to our charts , specifically i would like to know the probable sd for an stock in 1 week and 1 month , so do i apply parameter of 1 in these?, in the ! week it gives me a flat horizontal line ? when i place 1 as parameter.
Thanks.
Thanks.

On a daily chart, to get the standard deviation for a week (5 trading days, not necessarily a calendar week Mon - Fri), you would select "Standard Deviation" from the Indicator drop down on the Chart Workbench, and then put a "5" in the Parameters box. For a month, the parameter would be "21", which is the approximate number of trading days in a month.
