Hi guys,
How to read the VOLUME in this chart which is being displayed in the bottom chart in the attached screen shot ?
1. What do each of the 2 colors depict in this chart (the VOLUME section at the bottom) ? I do not get it ..
2. Is this the actual traded volume or is it only bid and ask volume ?
3. Is the volume twice the actual volume ? i.e. is each contract bought and sold considered one volume tick or is considered 2 ?
Thank you

For more about what is recorded in the chart, you need to look at the specific instrument and how that data gets recorded.
1. Colours on volume usually follow colour of candlestick body, ie. the direction of price from open to close during the session. So if price closed lower than open, the prevailing direction during the entire bar was down and red colour is shown. Reverse for green (or black) and close above open.
2. OHLCV charts and data usually records actual transaction price/volume aggregates (high, low, sum), and offers no concrete information on bid-ask.
3) Each and every transaction has a buyer and a seller, so counted once in volume, though each transaction may have a volume of 1 or greater as well, so cannot usually be used to measure number of ticks or transactions directly.
In general volume can be used to see "real activity" per time and/or price level. To start: Look at
the form of the candlestick containing the most volume. It is a red bar, but could there be buying interest there as well? How can you suspect so? Observe: It is the most significant bar in the chart, as it has most volume. What could the implications be if there were buying interest there, even though it was a red bar?
The next largest volume bar has a candlestick mostly red. Also understand that price moves to where there are interest in making the most real transactions (price discovery).
When low volume (little interest), price may break away from current price area and movement (trend
s).
Jack Hershey documented a full and complete methodology still to be found on ET, regarding how to interpret and trade based on volume. Look at my post history for more pointers.
