Goodday Apprentice,
Hope you are doing fine.
It is basically a minor tweak (I think so) to your "Bollinger band with alert" in this thread, viewtopic.php?f=17&t=60189&hilit=band+alert.
The tweak are as following:
1) When new candle's price is opening at outside (upper or lower of the) bollinger band
2) A separate windows (like stochastic indicator) attach at bottom
3) An alert will be produce by drawing a line (any color) in the windows mentioned at 2)
4) The line will remain on the screen for 10 seconds before disappear
5) The indicator shall work on M5 & M1 timeframe
I try to keep it as minimal code as possible if it can be modify from your existing "Bollinger band with alert" indicator.
I hope you will find it doable and not much extra effort to workaround.
Look forward to hear from you.
Thank you.
