Specification

Project Description
I need a simple and stable Expert Advisor for MT4 and MT5 that automatically places pending orders at defined distances from the current price and recreates them after activation and position closure.

Functional Requirements
1. Platforms
• EA must be developed for both MT4 and MT5 (two versions or a unified codebase).

2. Trading Logic
The EA must automatically place pending orders:
• 20 levels above the current price (every 5 pips)
• 20 levels below the current price (every 5 pips)
This results in a maximum of 40 pending orders, covering ±100 pips from the current price with the default 5‑pip spacing.
Order Behavior:
• When price reaches a pending order → the order is activated and a position opens.
• After the position is closed, the EA must automatically recreate a new pending order at the same price level.
• The EA must always maintain a complete grid (20 above / 20 below).

3. EA Input Parameters (External Inputs)
• Lot size (must support micro‑lots, e.g., 0.001)
• TP: 0–1000 pips (0 = disabled)
• SL: 0–1000 pips (0 = disabled)
• Distance between orders: default 5 pips
• Number of levels above/below price: default 20
• Trade direction:
• Long only
• Short only
• Long & Short
(must respect the Common tab settings)

4. Instruments
• EA must work on all FX pairs.

5. Technical Requirements
• Stable operation even with a large number of pending orders.
• Clean, readable, and well‑commented code.
• No duplicate orders.
• Must handle fast price movements correctly.

ثبت طلبك في مواصفات البوت الثاني كذا: الجودة والأمان أهم من السعر، وما يدخل إلا إذا الفرصة قوية، مع حماية عند الخسائر وانقطاع الاتصال وارتفاع السبريد، وتشغيل مستمر على سيرفر، مع اختبارات إلزامية قبل أي تشغيل حقيقي. بهذه الصيغة يصير يشتغل وأنت مرتاح بالِك، لكنه يوقف تلقائيًا وقت عطلة السوق أو أي خلل. بس أكون واضح معك: ما في بوت يضمن عدم الخسارة، خصوصًا بالمضاربات السريعة، هدفنا نقلل المخاطر ونمنع الخسائر غير المنضبطة
