مارکیٹ تک رسائی کے لئے REST اور Websocket موجود ہیں ، اور جب ویب ساکٹ کو کسی بھی ناقابل تسخیر عوامل کی وجہ سے ان کے کنکشن کو زبردستی منقطع کردیا جاتا ہے تو ، اس کی حکمت عملی میں غلطیوں کو برداشت کرنے کے لئے مختلف میکانزم کی ضرورت ہوتی ہے۔ REST اکثر سب سے زیادہ مستحکم طریقہ ہوتا ہے۔ جب آپ کے پاس ایک ہی پلیٹ فارم پر چلنے والی متعدد پالیسیاں ہیں ، جیسے OKEx ، اور یہ ایک ہی سرور پر چلتی ہیں ، تو REST API تک رسائی کی تعدد محدود ہوتی ہے (مزید تفصیلات کے لئے پلیٹ فارم API دستاویزات دیکھیں) ، اور اس کو محدود کرنے کے مختلف طریقے ہیں ، جیسے IP کی حد ، اکاؤنٹ کی حد ، یا دونوں کا مجموعہ۔ REST درخواستوں کی تعداد کو کم کرنے کے لئے مارکیٹ سینٹر کا استعمال کریں
