Risk Management Strategies

The Pro Tester includes Scaled Exits, Take Profit, Stop Loss, and Trailing Stop Loss in backtest calculations. This allows users to emulate risk management strategies for more realistic profit estimates.

Risk management elements do not influence backtest data displayed in the Pro Trader Calculations Table. The Calculations Table Comparison section provides further details.

See the Strategy Optimization section for details on incorporating Risk Management.

Trade Account Emulation

The Pro Tester allows trade account emulation. Users can specify Initial Capital (account size), Order Size, Pyramiding, Commission, and Margin for Longs or Shorts in Property Settings. These settings will be reflected in profitability data displayed in Strategy Tester Panel.

Trade Account Emulation does not influence backtest data displayed in the Pro Trader Calculations Table. The Calculations Table Comparison section provides further details.

Deep Backtesting

The Deep Backtesting feature of the Pro Tester allows backtesting within a specific date range. However, this feature is only available to TradingView Premium subscribers. See the Deep Backtesting section for details.
