New Custom signal feature is currently provided as beta.
It's idea to provide some sort of custom signal, user can design visually from some classical components. To the moment it's 2 MA cross & RSI & MFI levels possibly.
When user sets up the custom signal, no additional lines will be shown on the chart, only blue signal triangles if signal occurs.
This allows to add any lines to the chart separatelly.
MA settings for the cross are separated but RSI & MFI settings are taken from the app's appropriate "Settings" screen.

In landscape iPhone mode bottom toolbar are hidden to provide more screen space for charts.

New Intraday Background Scanner feature was developed for v.2.0.7.
When the appropriate setting is turned on, signals search via all symbols in app is made and their list is formed in the app memory. User should turn app into the background now. After intraday time frame period is over, local notification is delivered to user. Now he can start app by pressing on local notification banner. Signals search via all the symbols is made again and compared against previous signals. If signals' directions are changed, the message is shown.

About BB%B oscillator:
Thanks TayJT who offered to implement it. He provided the formula as it was developed by Tradestation members:
BB%B = 100 * ( Price - LowerBand ) / ( UpperBand - LowerBand ) ;
Ken Burkhalter modified it to scale chart from 100/0/-100:
BB%B = 100 * ((Price-LowBand) - (HighBand - LowBand)/2) / ((HighBand-LowBand)/2); This would more clearly show the deviation of a price from mean value.

Good luck!
