200 Day Moving Average should be business trading days not calendar days..FIX IT!!
The 200 Moving Average in "My Portfolios" is actually incorrectly a 139 business day moving average. Standard practice is 200 business days not calendar days. In fact the charting section in Yahoo by ChartIQ shows just that....200 biz days. Please fix it in "My Portfolio" section...people have been pointing it out for years!! all we get are useless replies to send screenshots and apologies but no action...a joke anyone would pay for premium if you cant even calculate a simple 200 day moving average.
