Task Title
Implement Martingale Lot Scaling Sync Between Master and Slave MT4 Trade Copier

Background
I am using a local master–slave trade copier setup with:

1 Master MT4

4 Slave MT4 terminals

Trades are currently copied correctly (entry, direction, symbol, SL/TP).

Lot size handling currently copies either:

the exact master lot, or

a fixed base lot defined on the slave (e.g., always 0.01 or 1.0).

Problem
When the master uses a martingale strategy, the slave does NOT follow the same lot-scaling logic.

Current Behavior
Example:

Master trades: 0.1 → 0.5 → 0.9

Slave (base lot = 1):
❌ Opens 1 → 1 → 1
❌ Or copies exact lot 0.1 → 0.5 → 0.9

This breaks martingale proportionality and risk alignment.

Required Change (Core Requirement)
The slave must follow the master’s martingale multiplier, not just the raw lot size.

Desired Behavior
The lot progression ratio on master must be mirrored on slave, scaled by the slave base lot.

Example 1
Master base lot: 0.1

Slave base lot: 1.0

Master Lot Multiplier Slave Lot
0.1 1.0
0.5 5.0
0.9 9.0
Example 2
Master base lot: 0.01

Slave base lot: 0.1

Master Lot Multiplier Slave Lot
0.01 0.1
0.03 0.3
0.09 0.9

write prompt for this funcation whare i have slave code i will give code implemt that features
