There are some new buttons on the bottom toolbar:
- Daily/Weekly/Monthly/Intraday (Intraday quantity is available via the first Settings menu) time frames selection. Attention to Google Edition users: as soon as it fully oriented on intraday bars the selector looks like Abbreviations mean 1, 5, 15, 30 minutes

In that mode indicators radiogroup is changed to oscillators radiogroup and 2-charts bottom panel button is changed to 1-chart mode selection button.
Curretly available oscillators are: MACD, Volume+Chaikin, BB%B, Slow Stochastic, RSI, CCI, ADX, MFI, Standard Deviation, Fast Stochastic, EliotW, QQE.
- - Refresh button allows to refresh data and redraw charts.
- - Market Scanner web app link (beta version);
- - indicators settings. By pressing it user will enter into Settings screen. It allows to tune MA, Bollinger Bands, Parabolic SAR, MACD, etc. indicators & oscillators:


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 "Settings" screen.

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.

More info about Fibonacci Bollinger Bands there: Fibonacci Bollinger Bands

Good luck!
