Inserting graphics on a chart based on a trigger

[jemtrading]

Is it possible to add a graphic, e.g. triangle, just below each bar on a chart based on something like RSI equal to 70 or above and an inverted triangle when RSI is equal to or below 30? Also, can you change colors of the bars? Any help would be appreciated. I am not very adept at creating formulas.

It is possible to do what you want using efs.
For instance see the formulas posted in this thread. Also try searching the forums for keywords such as rsi AND arrow* [or similar wording] and you will find other examples as these topics have been covered at length before.
With regards to painting the price bars see the examples provided in the Price Bars subfolder of Formulas which is in your eSignal directory and specifically the RSIPriceBars.efs. Also in this case try searching the forums as there are many formulas or code examples available that you may be able to adapt to your needs
If you are unfamiliar with programming in efs and are interested in learning then you may want to start by reviewing the JavaScript for EFS video series and the Core JavaScript Reference Guide. Those will provide you with a thorough introduction to programming in JavaScript which is at the foundation of EFS. Then go through the EFS KnowledgeBase and review the Help Guides and Tutorials which will provide you with the specifics of EFS. As you are learning continue to search the forums where you will find literally thousands of examples that you can use
