#:* If a tick is first one in the series, its volume goes to BUY volume.
#: <div style="background-color: #E3FBE5;">'''Note''': When you plot Volume Delta chart, take into account that it doesn't matter what resolution is selected, additionally MultiCharts will request '''historical tick ask''' and '''bid''' data from your data source for the specified in chart settings data range, if '''Ask Traded vs Bid Traded''' is selected. </div>
#: <div style="background-color: #E3FBE5;">'''Important information''': The logic described above is for data collected in real-time. The following logic is used for historical plots. '''Example''': Assume there are 3 historical trades, 9 historical bid quotes and 12 historical ask quotes. All of them have the same timestamp. To find out which historical asks and bids were used to generate the trades, they are all divided into 3 equal parts (because there are 3 trades). the first “batch” there are 3 asks, 1 trade and 4 bids. The most recent ask/bid matching the trade price is considered to be the price where the trade was made. If ask price is considered for the fill, then the trade’s volume goes to BUY volume. If bid is considered for the fill, then the trade’s volume goes to SELL volume..</div>
#* '''Up Ticks vs Down Ticks''' method:
#:* If the current tick price is higher or equals current ASK tick price, the volume of the current tick goes to BUY volume.
