###  | Volume Studies |

| The are several separate studies that can be applied with the Volume tab of the Studies dialog. These are selected by setting the radio button in the "Study Type" box, setting the other appropriate parameters and hitting [Apply]. Avg Method, Period, and Slowing period, only apply to certain studies as indicated below.
On Balance Volume and Price Volume Trend both attempt to show if there is more buying or more selling going on in a stock. Actually there is always equal buying and selling, since for every person selling, there is someone on the other side of the transaction buying. Both of these indicators are based on the assumption that if the price goes up for the day there must be more buying pressure, indicating that the stock is being accumulated, and if the price goes down the opposite is true. (Only the Line Attributes apply to these two studies). On Balance Volume (OBV) is just a running accumulation of each days volume. If the close price was lower than the open, the volume is considered negative and if the close was higher the entire days volume is considered positive. Price Volume Trend (PVT) factors in the amount of price movement in the calculation such that larger movements in price cause a greater portion of the volume to be factored into the accumulation. Average Volume shows the volume average over the selected period. Select also the desired Avg method. Relative Volume shows the current candle's volume as a percentage of the average of the prior Period candles. This result is averaged again by the smoothing period to smooth the curve. Intraday Relative Volume is available only on intraday charts. It shows the current volume as a percentage of the volume for the same (time frame) candles of the previous period days averaged. The resulting data is then average for slowing period candles of the current day to smooth the result. Intraday Accumulated Volume is only available on intraday charts. It compares the total volume for the day from the open up until the current candle with the average of the total volume from the open through the same time for the previous period days. This gives you an indication of how the volume so far for the day compares with the pattern of volume on previous days. Net Volume is only available on intraday charts and tick charts, when the charts are built from collected quotes. It does a better job than OBV and PVT of actually showing buying vs selling pressure. Net volume is the sum of all trades that occured at the ask or higher minus the sum of all trade volumes occuring at the bid or lower. Trades in between the bid and ask are not counted. Therefore positive net volume shows that more volume traded at the ask or higher (buying) and negative shows that more trade volume occured at the bid or lower (selling). Average Net Volume is the moving average of the net volume taken for period candles using the Avg method selected. Net Volume Ratio is the ratio of the sum of all the net volumes for the last period intervals divided by the total volume for the same period intervals expressed as a percentage (i.e. * 100). This shows what percentage of the total volume had a directional bias. The Line Attributes group specifies the Width as well as the of the color of the study line. The [Color] button is used to change the color of the line. Pressing [Apply] or [OK] creates or modifies the study.
