I saw your webinar, but I still don't get the way you are using the Weis Wave for volume. If you look at regular volume it does show up in TradingView; hence, my confusion. Now, for stocks...it is simpler. I do have some questions for you though.
I explained in a very simple way how to just take a common overview of the volume indicator. Using it this way is enough to make an educated guess. Dont worry too much about difference of volume bars in different indicators, just pick one and stick to it.
You are having the same trouble which a majority gets while trying to compare two different volume meters. In webinar, i told that volume, combined with price actin i.e. Supply and demand zones then gives a true picture. In my example price was in the middle so volume mattered a lot. In your chart, the low volume/high candle are on the verges, so definitely there, the price action counts more. Volume alone can not be used to make a full picture.
