NEW YORK--(BUSINESS WIRE)--Sep 30, 2026--

IvyDB TradeFlow is an evolution of OptionMetrics IvyDB Signed Volume and leverages a proprietary algorithm that delivers enhanced signaling and unmatched insights into order flow, participant activity, buy/sell pressure, and other critical analytics. It rapidly orders, classifies, and categorizes trade data from all U.S. exchanges, and sequentially processes data and analytics on retail and institutional investor trading at 5- and 30-minute, as well as end of day, intervals.

Designed to work alongside the gold standard in options data and analytics, IvyDB US, IvyDB TradeFlow tracks volume, buying and selling pressure, lot sizes, whether a trade occurred at the bid, ask, or midpoint for every option, every day since January 2016. It incorporates trade description codes and exchange venue data alongside Volume-Weighted Average Price (VWAP, or the average price a stock has traded at throughout the day) to more precisely assign directional volume and resolve midpoint trades. IvyDB TradeFlow also offers measures of trade aggressiveness relative to the SEC’s National Best Bid and Offer (NBBO) and proprietary indicators that identify and distinguish retail from institutional order flow.

“With the growing size and speed of today’s options market, and participation from retail investors, options activity can influence underlying stock prices, realized returns, and volatility. To evaluate strategies, Institutions need to understand how much is trading, who is driving activity and how aggressively they are positioning,” said Eran Steinberg, COO at OptionMetrics. “IvyDB TradeFlow offers a comprehensive view of trading across retail investors and market makers to identify shifts in positioning, liquidity and sentiment in rapidly changing markets.”

This chart illustrates total buyer- and seller-initiated trades of SPY options in 5-minute intervals on FOMC announcement day, with net imbalance defined as buyer-initiated minus seller-initiated volume. The chart indicates that heading into the 2:00pm ET release, the market broadly expected the Fed to hold its target rate. With the binary event resolved and no dovish shock to reprice, net options imbalance turned negative immediately after 2:00pm as traders sold contracts and unwound pre-announcement positions, representing post-event de-risking and volatility unwind. The chart was created with OptionMetrics’ IvyDB TradeFlow, which provides data and analytics on retail and institutional options trading and liquidity.

VATICAN CITY (AP) — The Incredible Hulk fulfilled a childhood dream by meeting with Pope Leo XIV on Wednesday.

Lou Ferrigno, who starred as the Marvel character during its 1977–1982 U.S. television run, met with the American pope and chatted briefly with him at the end of Leo's general audience in St. Peter’s Square.

“I’m here because it’s a lifelong dream for me to meet the pope,” Ferrigno told reporters. Noting that one side of his family hails from the southern Amalfi region, Ferrigno said he grew up hearing about the pope in a Catholic Italian family and served as an altar boy.

“I’m very, very honoured to be here to see Pope Leo, because it’s my whole life, it’s a dream coming true,” he said.

He posed for photographers, mimicking the gesture that made him famous in his on-screen transformation from Bruce Banner into the superhero Hulk — flexing his arm muscles.

Ferrigno, a retired professional bodybuilder, starred as Hulk in the CBS series before going on to other television and film roles. He noted that some had been filmed in Rome, and that he appreciated the pope's message.

"Our world, our country needs someone like him: A great leader about kindness and peace, because there’s so much turmoil happening in this world,” he said.
