How to use MAC3D_gate_v2

In the comparison image, this release — ver.2 — sits on the left, and ver.1 sits on the right.

Signals are frequent, so it is best to thin them out with your own judgment.
The chart shows what look like GMMA-style moving averages, but the logic underneath is built on MACD.
The signal timing is the point where MACD switches across its zero line, but the signal conditions run through a filter — as far as can be seen on the chart, the arrows seem to print slightly ahead of the actual switch.
A version 1 that uses a different filter is also distributed.
There appear to be roughly ten variants of this indicator in total.
