How to reset blockcount each bar

[gdavis74]

I have some code that draws a histogram using time and sales data volume. The idea is to plot the quantity of block trades for each bar. I have the code counting but the blockcount variable is cumulating each bar.

How do I reset the blockcount variable to zero at the start of a new bar?

Here is the code:

/// //initialize the blockcount variable

int blockcount = 0;


protected override void OnMarketData(MarketDataEventArgs e)
{


//Increment blockcount each time a trade of 1000 shares or greater comes in

if (e.MarketDataType == MarketDataType.Last && e.Volume >=5)
{
blockcount++ ;
}

}
protected override void OnBarUpdate()
{

Blocks.Set(blockcount);
}

gdavis74, you could reset your custom tracking variable in FirstTickOfBar in the OnBarUpdate() -

Bertrand, thanks for the quick response. That worked perfectly, I was able to monitor blocktrades today!
