Thank you, Peter. To tell whether the trade is a buy or a sell; If it is at the top of the curve, it is a buy volume. If it swings down; it is a sell volume. You add up the volume one bar at a time on the volume chart. It is a lot of work. So, you have to do it yourself. When the transactions are very busy, more than one trade may be included in the same bar of volume per minute(Yahoo is recording by the minute); then the irregularity comes in, volume can include both buy and sell trades. Quote.com one minute chart then shows you a vertical line which includes both buy and sell prices. On sparsely traded stocks, free Yahoo works fine. On balance volume is accumulative by the trades. After closing, on balance volume can be plotted by the day.
