Allow a stop loss criteria alert to be set as a percentage from the purchase price; not a previous closing price (or any other 'moving' price) since you have no reference point. This way you can 'see' the decline as it happens and be notified that the loss has crossed that percentage amount. This will avoid having to create multiple portfolios of the same stocks to be notified when a stock is down by 1%, 2%, 3%, etc...from purchase price. This is more accurate than your current stop loss criteria possibilities, in my opinion. Seems like it would be an easy addition.
