Reverse trade with adjustable lot size

I want you to build an Expert Advisor (EA) that mirrors trades between two accounts in opposite directions, maintaining identical TP and SL distances in pips with adjustable lot sizes. The EA logic is as follows:

✅ Core Requirements

• EA monitors trades opened on Account A.

• When a trade is opened on Account A:

• An opposite direction trade is opened on Account B.

• The TP and SL distances (in pips) are mirrored to the opposite direction.

• The lot size of the opposite trade is based on a configurable multiplier.

• If the original trade is closed, the mirrored trade is also closed.

• If TP or SL is modified on the original trade, it is updated on the opposite trade.

📊 Trade Examples (Different Lot Size Multipliers)

🔹 Example 1: EURUSD – Multiplier: 1.5

• Account A (Source):

• Buy 1.00 lot at 1.1000

• TP: 1.1050 (+50 pips), SL: 1.0950 (-50 pips)

• Account B (Opposite):

• Sell 1.50 lots at 1.1000 (1.00 × 1.5)

• TP: 1.0950 (+50 pips), SL: 1.1050 (-50 pips)

⸻

🔹 Example 2: GBPJPY – Multiplier: 2.0

• Account A (Source):

• Sell 0.40 lot at 184.20

• TP: 183.20 (-100 pips), SL: 185.20 (+100 pips)

• Account B (Opposite):

• Buy 0.80 lots at 184.20 (0.40 × 2.0)

• TP: 185.20 (+100 pips), SL: 183.20 (-100 pips)

⸻

🔹 Example 3: XAUUSD (Gold) – Multiplier: 0.75

• Account A (Source):

• Buy 0.80 lots at 2340.00

• TP: 2360.00 (+200 pips), SL: 2320.00 (-200 pips)

• Account B (Opposite):

• Sell 0.60 lots at 2340.00 (0.80 × 0.75)

• TP: 2320.00 (+200 pips), SL: 2360.00 (-200 pips)
