External Signals Strategy Tester v5

The External Signals Strategy Tester v5 indicator is a universal back-testing tool that allows users to evaluate external buy/sell signals with advanced money management and risk modules. It is designed to work with any input series, including other indicators or higher-time-frame conditions, providing a comprehensive environment for strategy optimization.

Usage

The Usage section focuses on how to integrate external data and configure the trade engine for various market scenarios.

Core Workflow

• Signal Integration: Use the "Buy Signal" and "Sell Signal" inputs to link external series. Any value crossing above 0 is treated as a trade trigger.
• Time Filtering: Restrict testing to specific periods using the Start and End Date inputs to avoid historical anomalies or focus on specific market regimes.
• Trade Management: Enable or disable Long and Short directions independently. Users can choose between simply closing a position on an opposite signal or reversing the trade direction (flipping).

Risk Management Modules

• Fixed Percentage Block: Apply classic Take-Profit (TP), Stop-Loss (SL), and Break-Even (BE) levels based on a fixed percentage from the entry price.
• Fibonacci Bollinger Bands (FBB): This module generates dynamic envelopes based on various moving average types (VWMA, HMA, SMA, etc.) and ATR-scaled Fibonacci levels. These lines serve as dynamic targets or trailing stops.

Details

The script operates on a modular logic where each exit component can be toggled independently. Upon a trade entry, the script activates the specific Long or Short module, ensuring that calculations for Stop-Loss and multi-stage Take-Profits are isolated to the active trade direction.

The Fibonacci Bollinger Bands utilize a dynamic multiplier calculated from the ratio of current ATR to a historical ATR, allowing the bands to expand or contract based on volatility trends. When "Trailing" is enabled for FBB exits, the script re-evaluates the exit price on every bar, updating the strategy orders accordingly. The classic percentage-based exits are processed in parallel and generally take priority if triggered simultaneously.

Settings

• Date Range: Sets the start and end timestamps for the back-test.
• Buy/Sell Signal: Input sources for the external entry conditions.
• Trade Settings: Master switches for enabling long/short trades and defining reaction to counter-signals.
• Risk %: Configures fixed percentage-based TP, SL, and Break-Even levels.
• Fibo Bands: Settings for the FBB overlay, including length, source, basis type (VWMA, HMA, etc.), and visual style.
• FBB LONG/SHORT SL & TP: Detailed sub-menus for setting up to 3 take-profits and a stop-loss using specific Fibonacci levels. Includes options for volume percentage to close at each target and trailing functionality.

FAQ

How do I access External Signals Strategy Tester v5? You can get access on the LuxAlgo Library for charting platforms like TradingView, MetaTrader (MT4/MT5), and NinjaTrader for free.

Can I use this script to generate its own entry signals? No, this script is designed as a management and testing engine; it requires external signals (from another indicator or source) to be plugged into the "Buy/Sell Signal" inputs.

Does this strategy support pyramiding (multiple entries)? The current version is designed for single-position management and does not support pyramiding; it holds a maximum of one position at a time.
