Good time to "un-facetious" - there was a risk that some of your readers could have wondered about your intelligence!
HA is an indicator, a kind of average, a way of making it easier for people who get shaken out of trends by small pullbacks to stay in. But they are not Price Action ... they are derivatives of PA and should be traded on that basis. I seem to recall, once when I did HA for Sierra Chart that you could gain information from having long vs short tails on the bars - like having some shorter and longer timeframe mas on a chart.
But they are not PA ... they are another derivative indicator.
And a HA pinbar is not a pinbar because it is derived from prices in this bar AND the prior bar.
IMO it is ultimately better for your trading (if you can do it and maybe it is not in your nature to be able to) to be able to stay in during the pullbacks without a crutch/training wheels like HA. But for some, particular indicators will always speak well to them and PA won't, in which case they are useful.
