The total_percent_investment_per_trade setting in MagicTradeBot is a key parameter in automatic DCA position sizing. It defines the maximum portion of your account balance that can be used for all DCA orders combined in a single trade, ensuring that your exposure remains controlled and risk is managed effectively.

🔹 1️⃣ How It Works

1. Caps Total Exposure

   • This setting limits the sum of the initial order and all subsequent DCA orders
   • Ensures that even if the market triggers all DCA levels, your total investment does not exceed the defined percentage of your balance

2. Integrates with Other DCA Parameters

   • Works together with:

     • auto_calculate_initial_amount → determines initial order size dynamically
     • max_orders → total number of DCA orders allowed
     • size_multiplier → scales each subsequent DCA order
   • Together, these parameters ensure safe, controlled scaling of DCA orders

3. Risk Management

   • Directly controls the maximum capital at risk per trade

   • Prevents accidental overexposure, especially important for:

     • High-leverage trading
     • Volatile coins
     • Multiple trades running simultaneously

🔹 2️⃣ Practical Example

Account Balance: $1,000 DCA Settings:

auto_calculate_initial_amount: true
total_percent_investment_per_trade: 5
max_orders: 3
size_multiplier: 1.2

Step 1 – Calculate Total Allocation

• 5% of $1,000 → $50 maximum for this trade

Step 2 – Calculate Initial and DCA Orders

• Initial order = $50 ÷ (1 + 1.2 + 1.2²) ≈ $15.15
• DCA 1 = $15.15 × 1.2 ≈ $18.18
• DCA 2 = $18.18 × 1.2 ≈ $21.67
• Total exposure ≈ $50 → matches total_percent_investment_per_trade

This ensures that no matter how many DCA orders are triggered, the total investment never exceeds 5% of your account balance, keeping your trade safe.

🔹 3️⃣ Key Benefits

🔹 4️⃣ Key Takeaways

• total_percent_investment_per_trade is the risk cap for each trade
• Works with automatic initial amount calculation, size multiplier, and max orders to safely scale DCA positions
• Ensures total exposure never exceeds your desired percentage of the account, even if all DCA orders are executed
• Essential for disciplined, risk-managed DCA trading, especially in volatile markets

In short, this setting is the main safety limiter for DCA trades, allowing MagicTradeBot to manage risk automatically while executing multiple DCA orders.
