Zorro Plugin [updated] 〈PREMIUM • 2025〉

// Called once when Zorro loads the plugin int PLUGIN_INIT(void) // Initialize resources, load ML models, etc. return 0; // 0 = success, non-zero = error

double PLUGIN_CALL(char* name, double* params, int nParams) if(strcmp(name, "sentiment") == 0 && nParams >= 1) // params[0] is a pointer to a string? Actually passed as double hack. // Better: pass ticker as string via a separate function. return get_sentiment((char*)(int)params[0]); // unsafe but illustrative zorro plugin

__declspec(dllexport) double PLUGIN_CALL(char* name, double* params, int n) if(strcmp(name, "add") == 0 && n == 2) return params[0] + params[1]; if(strcmp(name, "mul") == 0 && n == 2) return params[0] * params[1]; return 0; // Called once when Zorro loads the plugin
