Hi,
When retrieving historical ticks (TickHistoryTimeAndSalesExtractionRequest) for CL futures, there are trades with volume but no price.
Here are the field list :
'Trade - Price', 'Trade - Qualifiers', 'Trade - Volume', 'Quote - Ask Price', 'Quote - Ask Size', 'Quote - Bid Price', 'Quote - Bid Size', 'Quote - Qualifiers', 'Correction - Price', 'Correction - Qualifiers', 'Correction - Volume', 'Market Conditions - Qualifiers'
What does this means ?
