Whould I use fixed balance mode during backtesting?

Yes — using fixed balance mode in MagicTradeBot during backtesting is highly recommended. This ensures that all DCA and position sizing calculations are based on a consistent account balance, allowing for repeatable, reliable, and comparable results across different market scenarios.

🔹 1️⃣ How It Works

  1. Fixed Balance Mode

    • You manually set a balance value in the backtesting configuration (e.g., $5,000)
    • The bot uses this fixed balance as the reference for all initial and DCA order sizing
    • Ignores your live or fluctuating account balance

  2. Consistent DCA Calculations

    • Ensures that total_percent_investment_per_trade, size_multiplier, and max_orders produce identical order sizes in each backtest run
    • Prevents variations caused by previous trade outcomes affecting subsequent position sizing

  3. Repeatable Strategy Testing

    • Provides accurate comparison between different DCA strategies, settings, or money management sequences
    • Critical for testing across diverse symbols or market volatility conditions

🔹 2️⃣ Practical Example

Backtesting Settings:

auto_calculate_initial_amount: true
balance: 5000  # fixed balance for backtesting
total_percent_investment_per_trade: 5
max_orders: 3
size_multiplier: 1.2
  • Max DCA exposure = 5% of $5,000 → $250
  • Initial order = $75
  • DCA 1 = $90
  • DCA 2 = $85 (scaled to fit total $250)

Using a fixed balance ensures these order sizes are consistent across all backtesting simulations, regardless of hypothetical PnL from prior trades.

🔹 3️⃣ Key Benefits

Benefit Description
Consistency Order sizes remain the same for each simulation
Repeatable Results Enables reliable performance evaluation of strategies
Simplifies Analysis Easier to compare different DCA settings or money management sequences
Safe Testing Removes uncertainty caused by dynamic balance adjustments

🔹 4️⃣ Key Takeaways

  • Fixed balance mode is ideal for backtesting and demo simulations
  • Ensures predictable and repeatable DCA sizing
  • Makes strategy evaluation accurate across different market conditions
  • Supports testing of risk management, money management sequences, and leverage effects without interference from fluctuating balances

In short, fixed balance mode provides a controlled environment for evaluating DCA strategies, letting you see exactly how your settings would perform in live markets without unpredictable variables.
