Thanks for the Kudos! Getting the 4hour indicator on the 15 minute chart was a challenge but a great learning exorcise:D
As for the email, make sure it is set up correctly -> "tools", "options", "test".
I have it set so it only sends one email and then ignores any new triggers until the indicator is reset. I hate spam, (even spamming myself!). You can change this however by removing the "Send_Mail=false" line near the end of the code.
It seems to follow pretty closely Big Pippins with the rare difference explainable by different broker feeds having slightly different price values thus affecting the indicators. However remember that this system is really a training exorcise and you should never blindly follow any system that isn't well understood. So always display the cowabunga indicators on the chart and visually confirm what my indicator is telling you.
I won't be trading with real money until I have seen this profitable over at least 6 to 12 months. (My innate skepticism insists it won't be)
