Barchart’s Options Flow page highlights large option trades that are transacted across all US option exchanges for a particular symbol. Additional Report Date and data filtering options are available for Premier Members, along with the ability to download the data on the page to a .csv file.
Seeing what option strikes large institutional traders are buying or selling can provide both directional sentiment and volatility insights for the underlying security.
Bullish Sentiment is defined as calls traded on the ask or puts traded on the bid. Bearish Sentiment is defined as calls traded on the bid or puts traded on the ask. The histogram at the top of the page and the table shown at the bottom of the page includes these fields:
- Bullish Trade Sentiment and Bearish Trade Sentiment is the sum of the respective trade Premiums. The net difference (Net Trade Sentiment) is considered an indication of retail trade sentiment.
- Bullish Delta and Bearish Delta is Trade Size * 100 multiplied by Delta. Bullish Sentiment uses positive Delta and Bearish Sentiment uses negative Delta.
- The resulting Delta Imbalance provides insight into whether traders are bullish reflected by a high delta imbalance or bearish reflected by a large negative delta imbalance.
What's Included (Latest Date - Options Flow)
For the U.S market, the minimum options trade size is set to greater than 10 to eliminate the noise associated with smaller trades.

Special Labels
- To Open – A trade transacted between the bid and ask price.
(size of trade) > (strike OI) + (strike volume) – (size of trade) - Buy To Open – A trade transacted on the ask (offer) where the trade size is greater than the outstanding open interest and strike volume. This is typically construed as a bullish trade.
(size of trade) > (strike OI) + (strike volume) – (size of trade) - Sell To Open – A trade transacted on the bid where the trade size is greater than the outstanding open interest and strike volume. This is typically construed as a bullish trade.
(size of trade) > (strike OI) + (strike volume) – (size of trade) - Multi-Leg Spread Orders – (Coming Soon). When multiple options trade at the same time with the same underlying, this will show the other trades that occurred in the spread. Many times, the spread will transact at the same exchange as well.
