Mr.WT: ^Xparabolic

 
Hi, could you make audio alerts so sound when price touches the parabolic channels? I like this indicator and would like to watch it live how it behaves after touching the parabolica channels
 
also, it would be nice to code audio alert when parabolic channels change slope from up to down or from down to up...
 
and could you code an histogram of parabolic channels slope? (example slope up: green bars; slope down: red bars)

it would be an indicator like ShiChannelSlope that could help us to visually backtest the behaviour of the parabolic channels
