Audible Alerts for Key Levels on Multiple Symbols (18 min.) This video demonstrates how to setup audible alerts (and logging) for price approaching key levels such as the previous day session high or low.

Audible Alerts: Follow-Up Video (21 min.) This video is a follow-up to the first Audible Alerts video and discussions some alternate, efficient and dynamic methods for implementing these audible/visible alerts on key price levels.

Below are some videos and links that were references in the video above as good supplemental information:

User Variables and Reference Lines (video): This video illustrates how to use reference lines based on V# variables to set high and low alarms for a variety of symbols directly in a chart. This method also works well for reference lines based on High and Low Alarm levels.

Custom Price Level Alerts (video): This video explains how to create custom price level alerts for one or multiple symbols, which can be updated anytime by changing a value in a quotepage, or dragging a line in a chart.

New High/Low Alert Chart (chart definition): This chart produces audible alerts when new daily highs and lows are achieved on the symbol in the chart. The chart is set to session 2 (RTH) and will give signals for new RTH highs and lows, but simply change chart to session 31 to get Globex high/low alerts. These alerts will trigger only once per bar if applicable. To allow more frequent triggers, switch to a smaller periodicity like 15 second bars.

Alarms: Automating Alerts for New High and Low (24 min. ) This video demonstrates the Alarms functionality in Investor/RT and explains various ways to set and use alarms, including alerts for new highs and lows.

Notes from video

  • If you'd like to customize the alarm steps instead of setting each to the tick increment of the symbol, simply remove the SET(HISTEP and SET(LOSTEP entries in the scan syntax, and then manually change the steps in the appropriate columns in the alarm symbol quotepage. For example, certain statics or indices will need much higher steps than 0.01 or 1.

Alarms: Customizing High/Low Alarm Sounds for Each Symbol (8 min.) This video demonstrates how to give each symbol it's own unique high and low alarm sound.

Below are several definitions from objects used in the video, along with the syntax of the three scans used. Note: Unless you may have to change the quotepage associated with the imported scans depending on how you're using it. If you have already created or imported a quotepage named "alarmsSymbols" and are using that one, no changes are needed.

Syntax of Scans

  • Set Alarms Scan (Both Day and Globex): SET(MON, ALARM_LE) AND SET(LOALARM, SESST - TINC) AND SET(MON, ALARM_GE) AND SET(HIALARM, SESST_HI + TINC) AND SET(HISTEP, TINC) AND SET(LOSTEP, TINC)
  • Set Alarms Off Scan: SET(MON, -ALARM_LE) AND SET(MON, -ALARM_GE)
