Add 1 hour intraday

Please add 1 hour intraday in the next update and this app would be perfect. :)

AWESOME APP!!! Very reliable data and works perfectly. Keep up the great improvements. One of my top favorite stock apps now!!! Great job and thank you so much for making this app. Absolute must download for serious traders. Fantastic data and chart signals and now the working FourierPredictor. Very, very cool stuff in this app. Thank you so much.



I had heard about the Kalman filter (a fancy moving average) from electronics experience, but when I emailed Igor about the Heiken Ashi trend indicating technique he immediately incorporated it into the app and I had to buy the app. It gives very good signals in the weekly bar mode if you are doing more casual trading. Also, the Laguerre algorythm if tuned right can give very near the same signals Heiken Ashi. In the custom signal a 5 and 34 simple moving average will, I heard, give an Elliot wave type response.
