I think it's not contracts, it's shares. CITI as a trader had a three-legged position in Advaxis, then closed puts, while increasing the calls and reducing the number of shares. If the data were to reflect the number of contracts, that would have led to a huge disparity in their trading bias. Notice that the number of shares (held, and options) has to be on the same order.
