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

To improve usability:
