Hi Team, I am trying to trigger an alert for when the price moves a certain number of ticks (or points) within a short amount of time, like 500 ms. What would be the most accurate / efficient way to achieve that? My ideas so far: 1) ======================== I found 2 Studies: [Rate of Change - Points] and [Bar Difference] and was thinking to add one of those studies to a 500 ms candlestick chart, and set the alert trigger to = SG1 >= ABS(x) 2)========================== Another idea I had would be to use an X tick range chart and trigger an alert if bar start time - bar end time <= 500 ms ------------------------ Is there any better approach or ready study that I could use?

The studies: "numbers bars calculated values" and "numbers bars calculated values 2" has several velocity related outputs that may help.

Thanks, but I couldn't find any study that calculates rate of change over a period of time in those studies. I am still new to SC so maybe I overlooked something ? |

There are no native studies that can capture an intrabar value and then compare it to another.Is there any better approach or ready study that I could use?
In a word, no.Either of your two ideas are the best you can do with Simple Alerts, or spreadsheet studies, aside from a custom ACSIL study. |

Thanks. Will try the 2 methods - time bars with bar difference - range bars with bar start - bar end time and see how it works. The only issue I can see with these methods is if the fast move starts in one bar and goes to the next bar, then I wouldn't get the alert, for example: - I want to alert at 6 ticks over 500ms - in the first 500ms bar 3 ticks move happens, then in the next 500ms bar the next 3 ticks happen. In that case the individual 500ms bars might be less than the 6 ticks and hence not trigger the alert Any ideas how to tackle this scenario? Date Time Of Last Edit: 2023-12-23 22:43:55

It seems like something you will need custom written. ACSIL/C++ is the language SierraChart uses for custom charts rather than something built in. I have had good success working with Geoff at www.twofoxtrading.co.uk .

Any ideas how to tackle this scenario?
There is no way to always avoid this, aside from a custom ACSIL study.I think using a 6 tick range chart with the Bar Time Duration study, who's output is in SerialDateTime format, would be the easiest. Then compare its output with 0.5/86400 (a half-second) in a formula like this: =ID1.SG1<=0.5/86400 where ID1 is the Bar Time Duration study. This also would work: =ID1.SG1<=500/86400000 Spreadsheet Example Formulas and Usage: Formula Equivalents of Serial Date Time Values However, this doesn't solve your no-alert-when-overlapping issue, but it might have fewer missed alerts.
