The StockFinder builtin Stochastic RSI does not match TC2000 V17 version.  It does not have same parameters as TC2000.

Is RealCode possible for RSI of 5, Stochastic of 9, %K of 3?

You don't need to write any RealCode. You just need to change the Block Diagram for the StochRSI indicator in SF somewhat.

- Click on the StochRSI indicator to bring up the Edit window.
- Select Block Diagram to bring up the Block Diagram window.
- Left-click and drag on the Period input to the Stochastics block.
- Choose Select Block & Connect | Parameter: Whole Number.
- Double-click on the new block and select Edit.
- Change QuickEdit Field Name to Stochastics Period.
- Double-click on the Period block going into the RSI Block and select Edit.
- Change QuickEdit Field Name to RSI Period.
- Close the Block Diagram window.
- Click on the StochRSI indicator bring up the Edit window.
- Change the RSI Period to 3, Stochastic Period to 9 and %K Period to 3.

Building Your First 3 Block Diagrams (9:54)

You should be able to Open an attached Indicator directly into a running copy of StockFinder 5 (and save it from within StockFinder 5 if desired). You could also Save it to the \My Documents\StockFinder5\(Your Username)\My Indicators\ folder and then load it like you would any other Indicator (or Copy and Paste it there from wherever it Saves if you can't specify the destination directory when Saving).
