This study calculates and displays candlestick bars which represent the difference between Ask Volume V(ask)tVt(ask) and Bid Volume V(bid)tVt(bid) for each of the main price bars in the chart.
The High of a candlestick bar indicates the maximum difference between Ask Volume and Bid Volume that occurred during the formation of the main price graph bar. The Low of a candlestick bar indicates the minimum difference between the Ask Volume and Bid Volume during the formation of the main price graph bar. We express these ideas in mathematical symbols below.
