Hello,
I can modify the indicator for you. I am the programmer for MetaTrader from 2004 year. Main things: you should have the mq4-file of indicator. If you have not the mq4-file (programming text of indicator) and have only the ex4-file (executable file of indicator) then I can not modify the indicator.
About emails:
The MT4 can not send mails to any email-box, for example, the MT4 can not send mails to Gmail-box. At first, you should check your box: run MT4, go to menu "Tools" -- "Options" -- "Emails", make there all settings for your email-box and press button "Test". The MT4 will try to send the test-mail. If you don't make mistakes in settings then you should receive test-mail. If the MT4 can send test-mails to you then the indicator will also send mails to you.
You can go to my profile and see there the ~35 feedbacks about my programming jobs for MT4.
Sorry for my English.
Good Luck.
Serega Lykov.
