Copy Trading System Overview
1. Core Concept
Copy trading allows users to automatically replicate the trades of expert traders. Users invest money to "copy" an expert's trading strategy and receive profits/losses based on the expert's performance.

2. Key Components
Expert Traders (copytradings table)

Professional traders with profiles showing:
Win rate (percentage of successful trades)
Rating/reputation
Minimum investment amount
Trading performance history
User Copy Trades (user_copytradings table)

Records when a user starts copying an expert
Tracks: investment amount, current balance, profits, trade statistics
3. How It Works Step by Step
Starting Copy Trading:
User browses available expert traders
User selects an expert and enters investment amount (must meet minimum)
System checks if user has sufficient account balance
Money is deducted from user's account and allocated to copy the expert
A copy trading record is created linking user to expert
Profit Generation (Automated):
The system automatically generates profits/losses every 2-8 hours:

Profit Calculation:

Uses expert's win rate to determine if trade is profitable
Profitable trades: 0.5% to 4% of current balance
Losing trades: 0.2% to 2% of current balance
What Happens When Profits Are Generated:
Copy Trade Balance Updated: Profit added to copy trade's current balance
User Account Balance: Profit added directly to user's main account
User ROI Updated: Overall return on investment recalculated
Transaction Recorded: Each profit/loss logged in transaction history
Email Notification: User notified of significant profits (>5% of investment)
Stopping Copy Trading:
User can stop copying an expert anytime
Current balance (investment + profits) returned to user's account
Copy trade marked as inactive
Expert's follower count decremented
