Zorro Plugin [iOS Pro]

To improve usability:

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

double get_sentiment(const char* ticker) char url[256]; snprintf(url, sizeof(url), "https://newsapi.org/v2/everything?q=%s", ticker); // Perform HTTP request -> jsonResponse double score = model->predict(jsonResponse); return score; zorro plugin
