Description
V.2
- added discription on how to modify the behavior of the indicator
- added the possibilty to alert you on screen, with sound and by email (with special thanks to afhacker)
(added parts are in Bolt)
This is a modification on the Supertrend indicator of spka111.
This indicator projects 2 Supertrend indicators on 1 chart with customisable parameters. It will also display the high or low of the last changes above/below the candle that caused the change.
You can change the behavior of the Supertrend indicator by modyfing "_averageTrueRangelong" and "_averageTrueRangeshort" in the "Initialize()" part. Delete the ".WilderSmoothing". Insert a "." after "MovingAverageType". It will show you all the options you can change it to. This will affect the behavior of the indicator slightly and you can use it to fit your tradingstyle.
To let the indicator part send you emails, alert you on screen or play a soundalert I used a method developed by afhacker. He created an alert popup window. You can find his project here: https://ctrader.com/algos/cbots/show/1692. Here you will find all the info you need to make this work.
I will show you the Alert-lines I added to this algorithm to make it so it will create alerts on this indicator. The line you are looking for begins with "Alert.Factory.Trigger". The text between brackets e.g. "Buy Long" you can change to what you like that the alert will display. As afhacker describes is that the time it will show in the popup window and emails are in UTC. You can this in the popup alert settings to your liking.
Thank you afhacker for creating this great project!

I will upload the new indicator with email notifications when I get this working.
