যে কেউ আগ্রহী, এখানে কিভাবে একটি সূচক মধ্যে ব্যাকটেস্টিং ফলাফল করা একটি উদাহরণ. এটি আপনি অন্তর্নির্মিত কৌশল backtester এর সংক্ষিপ্তসার পর্দায় খুঁজে হিসাবে একই মান গণনা করে. এটি স্ট্যান্ডার্ড ব্যাকটেস্টার যেমন ব্যবহার করবে একই ফলাফল আকার যেমন 5 মিনিট চার্ট প্রায় 1 মাস তথ্য grabs, 1 মিনিট চার্ট তথ্য 1 সপ্তাহ grabs, ইত্যাদি... আমি এই হিসাবে স্বয়ংসম্পূর্ণ হিসাবে সম্ভব রাখা চেষ্টা তাই আমি সূচক নীচে ফলাফলের জন্য কোড অধিকাংশ রাখা. ফলাফল শেষ ট্রেড সংকেত এ থামবে অর্থাত একটি কিনুন এটি একটি বিক্রি আছে. এই একই সূচক আমি পিসিটি ট্রেইলিং স্টপ লস সঙ্গে পোস্ট তাই আপনি এখানে যে কোড দেখতে হবে। আমার পূর্ববর্তী পোস্টিং বলেন, সূচক শুধু একটি সহজ ক্রসওভার EMA কিছু উপযোগী দিতে এবং আমি আপনার নিজের সূচক ব্যবহার করার সুপারিশ না, কিন্তু আপনি যদি আপনি একটি কোড ফিরে কোড খুঁজে পেতে চান, তাই আপনি এটি পরিবর্তে একটি কৌশল সুইচ করতে পারেন।
