Volume profile

[arcadeindy]

Please add Session Volume indicator [Volume Profile].

[DaveSkender]

I’ll take a look at it. Do you have a good website reference to it that I can review.

Thank you for your reply.

We tend to avoid using random user customized indicators in this library, as in your link. Is there a more reputable version and source available? I’d like to stay with things that’s are published or recognized in professional journals or books.

I would like to find something like this. I think it’s a good indicator type to add.

Thank you sir.

[DaveSkender]

I'll continue to look for a version of a volume profile that we can use, so thank you for the idea. If you see something in your journey that might work, let us know.

@JGronholz, fyi

Hello, again, Dave! I couldn't find the source for TradingView's VP indicator, so I just asked Google what it was doing, instead, then wrote my own. I don't have any references to cite, unit tests, etc., etc., but I do have some free code for you that made this chart. I'll work through the contributing guidelines asap, but am currently unaware of the proper way to give you this. 🤷‍♀️🙏

This was to be part of my documentation, showing the "cliffs" where the price likes to stop.

To implement "Visible Range," just filter the quotes, like so:

results[klineInterval] = QuoteSource.Quotes[klineInterval].Where((quote) => { return ((quote.Date >= Chart.StartDate) && (quote.Date <= Chart.EndDate)); }).GetVpvr(Chart.YInterval / 4);

[JGronholz]

TradingView's VP indicator appears to output only the cumulative total, for only the last quote. I liked how your indicators are all time-series, and made this one the same. Each quote generates one VpvrResult, which each contain a list of VpvrValues(price/volume tuple) for that specific quote. The cumulative profile for a date is recursively assembled from those values.

When you move the cursor around, TradingView's VP indicator uses the Y value only. Since the output from my indicator can be indexed by date (X), before price (Y), the chart is able to visualize subsets of the volume profile. As far as I know, you cannot "time-step" like that, with TradingView's indicator. I often have to pan/zoom to impractical views of the candles, just to get their VPVR to show me what(when) I want. I began to work on a caching mechanism to improve performance, but put that on hold, for now. Currently, it's very functional.

When the cursor is not within my chart's ClientBounds, my app uses the last quote, producing an experience similar to TradingView's.

Volume Profile is one of the most powerful indicators, IMO, and is unavailable without a TradingView subscription. Coincidence? 😁

It's a business model!
