Hello again SC. I am trying to detect, using alert code, whether a specific event happened within the last few bars. Right now, I am writing the condition to detect, bar by bar. So if I want to detect if the event has happened within the last 20 bars, I have to write: =and(ID1.SG1[-1]<X,ID1.SG1[-2]<X,etc,etc,etc) Is there a way to more easily detect for events? Something that would only require 1 line of code, or perhaps a study that does this? I know I can use spreadsheets to look for matches in an array, but that taxes my server's power too much. Any help is much appreciated. Thank you for reading! -Ben |

The ability to do this was added in release 1735. You would need to update to that version to be able to use this feature. The documentation for using a Range of Values in an Alert Formula is found here: Study/Chart Alerts And Scanning: Referencing A Range of Data To update, follow the instructions here: Software Download: Fast Update For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

I think I love you guys. Hands down, you have the best platform, great indicators, and an awesome support board. I can't wait to begin writing my own code for SC... Thank you for everything -an old user. |

This particular formula cannot be directly rewritten using a range of values: =and(ID1.SG1[-1]<X,ID1.SG1[-2]<X,etc,etc,etc)
A range is only going to be useful when used with a spreadsheet function which requires a range. Sierra Chart Support - Engineering Level Your definitive source for support.
