I'm a bit confused about the numbers shown in volume. Take this chart for example:

enter image description here

You can see in daily candle the volume is 14M but if I show 1h candles and sum all the 7 candles of the day the volume is less than 1M !
Why is that?
I thought the volume was the total number of shares (not lots) transacted in that time.

EDIT: This is the 1h candles in investing, which shows 14M in volume for the 7h, which is OK with the daily volume. So maybe Tradingview.com is not showing the correct volume in 1h candles???

  • FWIW on investing.com/equities/alibaba-candlestick switching between time periods the volume seems to add up to the daily on 3/1 as you'd expect. – Hart CO Mar 3 '19 at 2:12
  • @HartCO is just a normal chart in TradingView, and yes, I know the volume is a different bar char, is shown on the image, you have the candles and the volume, I don't understand what you mean – Enrique Mar 3 '19 at 16:54

    If the data provider shows a different total for the sum of intraday data versus the daily data total for that same day then they're providing bad data. – Bob Baerker Mar 3 '19 at 17:43
  • @BobBaerker is TradingView.com, I think maybe there is something extra to check? maybe the daily candles includes also the premarket transactions and them are much higher than transactions during the day? – Enrique Mar 3 '19 at 18:22

    You'd have to inquire with their support to get an answer for what they are doing with their data, other sites get this right, so clearly they are either doing something incorrectly or their volume numbers mean something unconventional. This person noted an issue with intra-day volumes as well, it appears unreliable: tradingview.com/script/EPkIK2JF-Volume-Problem – Hart CO Mar 3 '19 at 18:38

OK, it seems to be a problem with TradingView.com
I have contacted with their support and they said this:

According to your chart snapshot, you are viewing data provided by Cboe BZX. Please note that Cboe BZX is an electronic exchange that doesn't charge per user fees for real-time data. However, such data is slightly different from its official counterpart from primary exchanges - it offers approximate volumes and fewer price updates.

And they are saying "slightly different" while is a HUGE difference, daily volume is 14M and intraday sum is less than 1M! that makes the volume intraday data completely useless in TradingView

  • Daily volume is the sum of all of the volume traded on the various exchanges. Showing you just the volume from one exchange (BZX) is worthless info. – Bob Baerker Mar 4 '19 at 13:44
