why is BuyVolume buys+sells

[alanlopen]

In the official BuySellVolume, the Buy volume is buys+sells, but why ? Normally buys+sells is the entire volume and BuyVolume should be buys only right ?

protected override void OnBarUpdate()
{
if (CurrentBar < activeBar || CurrentBar <= BarsRequiredToPlot)
return;

// New Bar has been formed
// - Assign last volume counted to the prior bar
// - Reset volume count for new bar
if (CurrentBar != activeBar)
{
Sells[1] = sells;
Buys[1] = buys + sells;
buys = 0;
sells = 0;
activeBar = CurrentBar;
}

Sells[0] = sells;
Buys[0] = buys + sells;
}​

Hello alanlopen,

Because that indicator uses two plots that overlay as bars the buys would not be visible if only the buy data was included in that plot. This indicator is for visual only purposes. You can use similar logic to that in your own script if you wanted to accumulate data from OnMarketData and did not need to visualize it, you would in that case use just the buy volume for buys.
