আমি উপরের উত্তর অনুসরণ এবং ইয়াহু ফিনান্স দিকে তাকানো শুরু। তাদের এপিআইতে বিভিন্ন উপায়ে অ্যাক্সেস করা যায় তবে আমি সিএসভি হিসাবে স্টক সম্পর্কিত তথ্য পাওয়ার জন্য একটি দুর্দান্ত রেফারেন্স পেয়েছি: http://www.jarloo.com/
এটি ব্যবহার করে আমি এই স্ক্রিপ্টটি লিখেছি। আমি আসলেই রুবি লোক নই তবে এটি আপনাকে একসাথে কিছু হ্যাক করতে সহায়তা করবে। ইয়াহু যে সমস্ত ক্ষেত্র অফার করে তার জন্য আমি এখনও ভেরিয়েবলের নাম নিয়ে আসিনি, সুতরাং আপনার যদি প্রয়োজন হয় তবে আপনি সেগুলি পূরণ করতে পারেন।
