کثیر پلیٹ فارم ہیجنگ استحکام ثالثی V2.1 (منشور ایڈیشن)
مصنف:روبی, تخلیق: 2018-08-27 14:16:49, تازہ کاری:ہیجنگ کی حکمت عملی ایک نسبتا risk خطرناک اور مستحکم قسم کی حکمت عملی ہے۔ ہیجنگ ایک ہی وقت میں مختلف مارکیٹوں میں تجارت کرکے منافع حاصل کرنا ہے ،
پروگرام کا منطقی بہاؤ
اسٹریٹجک تشریح
یہ حکمت عملی متعدد ڈیجیٹل کرنسی اسپاٹ پلیٹ فارمز پر ہیجنگ لین دین کو آسان کوڈ اور بنیادی ہیجنگ کی صلاحیتوں کے ساتھ حاصل کرسکتی ہے۔ چونکہ یہ ورژن بنیادی تدریسی ورژن ہے ، لہذا اصلاح کی گنجائش بہت زیادہ ہے۔ نئے صارفین اور نئے ڈویلپرز کے لئے جو حکمت عملی لکھنا سیکھ رہے ہیں ، یہ ایک اچھی مثال اور کچھ مہارت فراہم کرسکتا ہے۔ مقداری حکمت عملی لکھنے کی تکنیکوں پر عبور حاصل کرنا بہت مددگار ہے۔
حکمت عملی کو حقیقی مارکیٹ میں ڈال دیا جاسکتا ہے ، لیکن چونکہ یہ تدریس کا سب سے بنیادی ورژن ہے ، اس کی توسیع ابھی بھی بہت بڑی ہے ، اور جو طلباء اس خیال پر عبور حاصل کر چکے ہیں وہ بھی حکمت عملی کی تعمیر نو کرنے کی کوشش کرسکتے ہیں۔
