SATO Options Flow Screener

Option flow, also known as options order flow or simply "flow," refers to the real-time tracking and analysis of the buying and selling activity of options contracts in the financial markets. Options are derivative financial instruments that give investors the right, but not the obligation, to buy (call option) or sell (put option) an underlying asset (such as stocks, indexes, commodities) at a predetermined price (strike price) within a specified timeframe.

Option flow analysis involves monitoring the volume, price, and direction of options trades being executed in the market. This data can provide insights into the sentiment and expectations of market participants, helping traders and investors to gauge potential future price movements of the underlying asset.

Here's how one can use option flow to make decisions in the stock market:

• Identifying Unusual Activity: Unusual option flow refers to significant changes in trading volume, particularly in comparison to open interest or historical volume. A sudden surge in options trading volume can indicate that informed traders or institutional investors are placing significant bets on the future movement of the underlying stock.
• Directional Bias: By analyzing whether more call options (betting on a price increase) or put options (betting on a price decrease) are being traded, traders can gauge the overall market sentiment regarding a particular stock or index. If there's a higher volume of call options being traded, it might suggest bullish sentiment.
• Strike Price Analysis: Observing the distribution of options trades across various strike prices can provide insight into where market participants expect the stock price to move. For example, if there's heavy trading activity at a specific strike price, it may indicate a level that traders expect the stock to reach.
• Expiration Analysis: Different options contracts have different expiration dates. Monitoring options trades across various expirations can offer insight into the time frame in which traders expect a significant price move to occur. These are frequently tied to expect catalyst events like earnings or other major announcements.
• Size of Trades: Large trades, often referred to as "block trades," can indicate the involvement of institutional investors or high-net-worth individuals. These trades are generally considered to be more informed and can influence market sentiment and direction.
• Confirmation or Contradiction: Option flow analysis can be used to confirm or contradict other technical or fundamental analysis methods. For example, if a stock is showing bullish technical indicators and there's also bullish option flow, it might provide stronger evidence for a potential price increase.
• Risk Management: Option flow data can also provide insights into potential support and resistance levels. Traders can use this information to set stop-loss and take-profit levels for their positions.

It's important to note that while option flow analysis can provide valuable insights, it's not a guaranteed predictor of market movements. Options trading is complex and involves significant risks. Traders should combine option flow analysis with other fundamental and technical analysis methods and have a thorough understanding of options trading strategies before making trading decisions. Option flow analysis can provide several additional insights beyond those mentioned earlier.

Here are some additional insights that traders and investors can gain from studying option flow:

• Earnings Expectations: Options activity can intensify leading up to a company's earnings announcement. Traders can analyze option flow to understand market sentiment and expectations surrounding earnings reports. Elevated options activity might indicate heightened anticipation of a significant price move post-earnings.
• Event-driven Trading: Option flow can be influenced by significant events like mergers, acquisitions, regulatory decisions, and economic data releases. Traders can use option flow to gauge market participants' reactions and expectations related to these events.
• Hedging Strategies: Institutional investors often use options as part of their risk management strategies. Monitoring large options trades can provide insights into whether institutions are using options to hedge against potential losses in their portfolios. These are frequently part of multi-leg transactions.
• Market Maker Activity: Market makers are intermediaries that facilitate options trading by providing liquidity. Analyzing option flow can reveal the activity of market makers and how they are adjusting their positions to manage risk.
• Unusual Options Strategies: Some traders use complex options strategies that involve multiple contracts and combinations of calls and puts. Analyzing option flow can help uncover these unusual strategies and potentially provide insights into the trader's outlook on the market.
• Sector and Industry Trends: Option flow can provide insights into sentiment across specific sectors or industries. If there's a surge in options activity related to a particular sector, it may indicate changing sentiment or expectations within that sector.
