Options Volume and Open Interest Indicators Usage Notes February 2015 This suite of six indicators is designed to monitor volume and open interest in options, issue by issue. Many traders want to monitor, as well as sort and rank, symbols for high levels of options activity as precursors or confirming indications of price action in the underlying asset. Each of these indicators includes alert criteria (for real-time alerts and sorting in RadarScreen ) that are much more useful than the alert criteria in the TradeStation-supplied options volume indicators. The alerts in the Labs suite are based on volume or open interest exceeding its recent average, with user-defined lengths and percentages. (The TradeStation-supplied options volume indicators allow alerting only by absolute volume level, and there are no alert criteria for open interest.) These are the six indicators in the suite. Their names are self-explanatory. TSL:Volume - All Opts TSL:Volume - Calls TSL:Volume - Puts TSL:Open Int - All Opts TSL:Open Int - Calls TSL:Open Int - Puts These indicators may be used in charting and RadarScreen and Scanner. The data should be formatted for daily or greater bars. Any combination of these indicators may be used in any particular chart or RadarScreen window. There is a sample workspace provided with the indicators. TSL Options Volume and OI contains: a chart and RadarScreen window with the two All Opts indicators a chart and RadarScreen window with the two Calls indicators a chart and RadarScreen window with the two Puts indicators a RadarScreen window with the three Volume indicators.
