Can a sierra chart study produce a visual que in the RSI study's chart region indicating that the difference between the current and previous RSI values is less than 10, without the use of acsil or a spreadsheet? It could be an arrow, a red/green status light, a 2-digit number, etc.

You could use the "Color Bar Based on Alert Condition" to do this. Your Alert condition would look like the following: =ABS(ID1.SG1 - ID1.SG1[-1]) < 10 Where ID1 is the ID of the RSI study on your chart. Refer to the following, in particular note the section on "Drawing Arrows/Text or Other Styles at the High or Low of Bars": Color Bar Based on Alert Condition For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing

Works great, Thank You. Could a sierra chart study give visual que alerts for engulfing patterns, without using acsil or a spreadsheet? The Sierra Chart's Engulfings use a different formula than what is required. If there is a way to edit those, great, but if not, the original question remains.

We are assuming that you are using the "Candlestick Pattern Finder". If so, then the source code for this can be found in Studies4.cpp including the formulas. So you can modify this and create your own study to do what you want. Refer to the following: How to Build an Advanced Custom Study from Source Code Otherwise, you could try to use the Color Bar Based on Alert Condition, as you should be able to create the condition using the alert syntax without too much trouble.

"We are assuming that you are using the "Candlestick Pattern Finder"." No, Sierra Chart's "candlestick pattern finder's" Engulfings use a different formula than what is required. Troubleshooting - This Chart Study Color Background Based On Alert Condition will alert correctly in hindsight when the study is re-applied to the chart, only to miss new realtime occurances. It often fails to perform in real time. After reapplying the Chart Study, the Color Background appears where none existed before for multiple bars that qualify for color background. Interestingly, a Red Highlight Does appear appropriately and correctly behind the Study Name in the Chart Header during bar formation but upon bar completion these bars themselves do not become 'color backgrounded' unless the study is re-applied to the chart again.

What are the following Inputs set to: - Number of Days to Calculate - Automatically Clear from Before 'Number of Days to Calculate' Also, on the Alerts tab, do you have the option for "Evaluate on Bar Close" enabled or not?

Your Alerts have '[1]' in them instead of '[-1]'. By having a +1 in there, it is trying to look forward, which is why the current bar never colors, but it will color previous bars when you apply the study later (those bars then have a bar forward of them).
