MAC-Z VWAP Indicator [LazyBear]

This a modified MAC-Z using Z-VWAP. Since this uses VWAP, the signals are derived indirectly from both volume and price action.

I have also included a way to smooth MACZ-VWAP, you can enable it via options page.

Note that this will not work on any FX pair, as volume is not available.
