Compare like periods and like data
For shares, volume is commonly expressed in shares traded; for futures, in contracts. Every completed transaction has a buyer and a seller, so total volume does not mean there were more buyers than sellers. Open interest is different: it measures outstanding contracts rather than turnover during the session.
The comparison baseline matters. A full trading day should be compared with completed days using compatible session coverage. A partial day, holiday session or contract rollover can distort apparent activity. Some markets have consolidated reporting, while others provide one venue’s volume or a count of quote changes. Identify what the field actually measures.
An active breakout can still fail
Assume a share closes above a 40-dollar resistance area at 41.00. The completed session trades 1.80 million shares versus an average of 1.20 million over the preceding 20 completed sessions. Relative volume is 1.80 / 1.20 = 1.5, or 50% above that baseline. This records an upward close accompanied by greater turnover. If the following close is 39.50, price has returned below resistance despite the earlier activity. Calling the first session confirmed institutional accumulation would go beyond the available evidence.
Activity can accompany agreement or a turning point
High turnover may occur during sustained trends, forced liquidation, index changes or a sharp reversal. Low turnover does not automatically invalidate an advance. Averages are also sensitive to exceptional sessions; a median can offer a different baseline. Volume is useful context, but a single ratio cannot identify the economic reason for trading.
Check the price result after the active session
On an available completed daily, weekly or monthly price chart, identify the boundary and subsequent closes. Where compatible volume data are available separately, note the unit, venue, session coverage and baseline dates. Compare whether price held the move after the active candle. Do not infer that Student Wyckoff Pro includes every volume feed or a dedicated volume-analysis tool.

Your next practical step
Examine the completed price result and compare participation only where compatible volume is available.
