Hi, we're using TRTH downloading tick level data. We requested many columns from TRTH as below. I am wondering is there a field or trade flag that helps us to identify whether a trade belongs to Pit trade or not?
https://www.investopedia.com/terms/p/pit.asp

The reason is for some futures products in 2000-2006, we see many trades with prices, but volume as 0, we're wondering whether these trades are pit trades.

Thanks
