My only criticism is that its hard to tell where the stock was after the time-window is grown after I click buy/sell. If i click back, then I can see, but otherwise its kinda hard. If you could put a little vertical red line over the image where I bought/sold the stock, it'd help figure out what happened. I know you're just pulling a picture from yahoo finance, but since the time-window change is always the same, the red line should always be over the same spot.
