Channel Trend Lines

Indicator introduction:

•  A channel and trend line indicator, which is a good tool for manual trading, and also can be used for creating new EAs, without drifting or repainting.
•  It applies to any timeframes and any symbols. 
•  The work of the indicator is shown in the screenshots.

For any novice and programming trading friend, you can write the signal into the EA to play freely, buffer 0 corresponds to the bold trend line, buffer 4 and 5 respectively corresponds to the channel's upper and lower frontier.

Parameter introduction:

• Sound Name: The alert sound file name, which must be located in the "...\drive_c\Program\Files\MetaTrader5\Sounds\alert.wav" folder.
• Repetitions: The number of alert/email/notification repetitions when every time to inform you.
• Pause, in seconds: The pause between two consecutive alerts/emails/notifications.
• Use Sound: flag, whether or not to play the system sound.
• Use Alert: flag, whether or not to use alert reminder.
• Use Send Mail: flag, whether or not to use email reminder.
• Use Send Notification: flag, whether or not to push messages to mobile phone.
