VWAPThe VWAP Study plots the Volume Weighted Average Price as generated by our streamers on a trade by trade basis. This is a moving average over the last 15 minutes, weighted by the volume behind each trade.
As this value is generated on our servers before being transmitted, it has a few limitations. Firstly, its period cannot be changed from 15 minutes. It also is limited to working on LSE stocks whose price is generated by AT Trades, namely SETS stocks. It also cannot operate historically, ie the study will start working the moment it is selected and onwards, but will not show values from the past. The Volume Weighted Moving Average avoids each of these problems, so may be of more use on other exchanges and for historical values, but it operates on a minute by minute case, rather than trade by trade.
Under the edit options you can select whether the VWAP is drawn as a line (the close of each minute) or as candles (the default value)
