You need to go to your chart setting wheel, go to appearance then uncheck "fill up". That way you can see if stock going up or down. Hope this helps.Hello Christopher, your studies are really amazing. I'm in the learning phase and don't have any experience with coding so hopefully this isn't a silly question. I've notice on your charts there are hollow candles mixed in with the solids that never appear on my charts. Can you tell me why I'm not seeing those on my charts and what signals do they represent? thanks for all the hard work you have put in these studies.
