To improve usability:

Compile (MinGW):

function run()

plugin("myplugin.dll"); print(plugin_call("add", 5, 3)); // prints 8.000000

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

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