الساعة فجراً، الهاتف يهتز بلا توقف، وكل رسائل الصوتية تتكرر بنفس المحتوى: "أنا أفتح مركز شراء ب50 ضعف على 5000U، فقط تصحيح 3% و الحساب يختفي... ما الذي يحدث؟" بعد مراجعة سجل التداول، ارتفعت ضغط الدم مباشرة—— 4750U تم المخاطرة بها بالكامل، ولم يكن هناك أي وقف خسارة.

**السبب الحقيقي لانفجار الحساب بالكامل: ليس مضاعف الرافعة المالية، بل نسبة المركز المفتوح**
لا تلوم الرافعة المالية مرة أخرى. ما هو العدو الحقيقي؟ نسبة المركز المفتوح مبالغ فيها جدًا.
خذ مثالاً على حساب 1000U لتوضيح الأمر: فتح مركز ب900U مع رافعة 10 أضعاف، فقط يتحرك السوق عكس الاتجاه بنسبة 5%، الحساب يُصفى مباشرة؛ بالمقابل، مع 100U ورافعة 10 أضعاف، يحتاج السوق أن يتحرك عكس الاتجاه بنسبة 50% ليحدث الانفجار.
ذاك الصديق وضع 95% من رأس ماله بالكامل، حتى مع رافعة 10 أضعاف، بمجرد أن يحدث تصحيح بسيط في السوق، يُطرد مباشرة من السوق. هذه ليست مشكلة الرافعة، بل كارثة توزيع المركز.

**ثلاث قواعد ذهبية، خلال نصف سنة باستخدام مركز كامل بدون انفجار، يمكن مضاعفة الأرباح**
استخدام المركز الكامل ليس مستحيلاً، المهم هو وجود خطة واضحة. بفضل هذه القواعد الثلاث، تجنبت العديد من الفخاخ المميتة:
**التحكم في حجم المركز في حدود 20% من إجمالي التمويل** — حساب 10,000U، أقصى استثمار 2000U. حتى لو أخطأت في التقدير، مع وقف خسارة 10%، ستخسر 200U فقط، ولن تتضرر بشكل كبير، ويمكنك دائماً العودة من جديد.
**تحديد الحد الأقصى للخسارة عند 3% من إجمالي التمويل** — مثلاً، مع 2000U ورافعة 10 أضعاف، وتحديد وقف خسارة عند 1.5%، ستخسر 300U فقط، وهو 3% من التمويل الإجمالي. حتى مع عدة أخطاء، لن تموت، وستحتفظ برأس مالك للعودة مرة أخرى.
**عدم التداول خلال فترات التماسك، وعدم追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追追
