Rename Strategies with Batch Find & Replace – Custom Analysis

Ideal if you want to quickly create clean, informative names across a whole databank – this Custom Analysis snippet lets you batch rename strategies in StrategyQuant X using simple find → replace (or just find → remove).

— What it does

• Runs as a Custom Analysis (Full databank analysis).

• Input args accepts find=>replace or just find to remove.

• Renames in place in the selected Source databank.

• Literal, case-sensitive match. Supports \n, \t, \r.

• Great for mass cleaning: trim prefixes/suffixes, remove words, standardize symbols/timeframes/directions.

— How to install

1. Code Editor → New → Custom Analysis, name the file CARenameFindReplace
2. Paste the code (below) and Compile.
3. If needed, restart SQX.

— How to use

1. Custom Project → Task → Custom Analysis.
2. In Full databank analysis, select CARenameFindReplace and choose your Source databank.
3. In Input args enter one of:
   -
   Replace: old=>new
   Remove: old
   -
4. Run. All strategy names in the Source databank are updated.
5. Reload the databank to see the change.

— Examples

• Remove the word “Strategy ” (with trailing space):
  Strategy =>
• Convert SQX auto-name to a formatted label:
  Strategy =>XAUUSD_H1_L_
• Strip dots after a prefix pass:
  .=>

Tip: Run multiple passes for multi-step formatting (e.g., add a prefix, then strip characters, then add a suffix). Consider duplicating the databank first if you want an easy rollback.

public class CARenameFindReplace extends CustomAnalysisMethod {

        String raw = getInputArgs();

        // Support "find=>replace" OR just "find" (remove)
        String find, repl;
        int arrow = raw.indexOf("=>");

                if (oldName == null) continue;
                String newName = oldName.replace(find, repl);
                if (!newName.equals(oldName)) {
                    rg.setName(newName);

                }
            }
        }
        return databankRG; // no filtering, just rename in place
    }

    private static String unescape(String s) {
        if (s == null) return "";
        return s.replace("\\n", "\n").replace("\\t", "\t").replace("\\r", "\r");
