Awesome Oscillator with alerts

Hi,

I would like to have an Awesome Oscillator indicator according to the following terms

• The indicator should be identical to the Awesome Oscillator indicator by Bill Williams
• The indicator should have the ability to draw two signal lines
• The indicator should have an option for alerts
• When the Zero Line has crossed
• When the Signal Lines have crossed
• The indicator should have an option to draw a vertical line when one of the above alerts is triggered
• The vertical line should extend to the main chart window and not just the secondary chart window (see attached picture)
• The alert should be on one bar back not on the currently forming bar
• Alert should be triggered once per signal
• The indicator should have the ability to change the histogram color
• The indicator should have the ability to add levels
• If both signals have the same settings, effectively shown as one signal line, the alert shouldn’t be triggered
• The indicator should produce clear signals for an EA, if one would be built around it (or at least, explain to me how to read the signals into an EA, for learning purposes as I’m not so well educated with MQL)
• The indicator should be written in MQL4 and will run on the Meta Trader 4 platform, latest version

The user settings should have the following options available

• First signal MA
• Period
• Shift
• MA method
• Color and Line format
• Second signal MA
• Period
• Shift
• MA method
• Color and Line format
• Alert on Zero Line cross – True/False
• Alert on Signal Lines cross – True/False
• Alert type
• Email – True/False
• Pop up – True/False
• Vertical line – True/False
