The Playground Series v1 to V4 - A combination of trading concepts - expert for MetaTrader 5

This code is not optimized and is provided as-is for educational and experimental purposes.

The Playground EA series was created to experiment with Fair Value Gap (FVG) and liquidity concepts. These Expert Advisors are designed to test different trading models and observe how different strategies perform under different market conditions. The author does not recall specific implementation details as these were quick experimental builds.

Please feel free to use, modify and study this code. It is fundamental to understanding trade based on aggression

g strategic and liquidity objectives.

The Playground EA series consists of five versions (v1.00 - v1.04), each introducing new features, improvements and bug fixes. All versions use the FVG library, and most versions utilize the liquidity library for market analysis.

Core concepts for all versions:

Status: Initial experimental version with dual-mode functionality

Description: The first iteration introduced two different trading modes: expropriation scalping and liquidity scalping. This version attempts to combine FVG detection with liquidity level scanning.

Input parameters:

Magic number: 9999

Status: Simplified and Practical - Removed Liquidity Mode

Description: Version 1.01 addresses key issues in v1.00 by removing the non-functional liquidity scalping mode and focusing entirely on expropriation scalping. This results in a clean, efficient implementation.

Changes in v1.00:

Input parameters:

Magic number: 9999

Status: Silver Bullet Timing Dual Mode Reintroduced

Description: Version 1.02 reintroduces the second trading mode, but with a completely different approach. Instead of liquidity scalping, it introduces the Silver Bullet mode with timed trading windows and liquidity targets. This release also changes the way modes operate - now uses enumeration-based selection.

Changes in v1.01:

Silver bullet features:

Input parameters:

Status: Parallel mode execution with appropriate DOL implementation

Description: Version 1.03 has been significantly refactored to allow both trading modes to run simultaneously and independently. It also corrects the Silver Bullet time window to match the liquidity library implementation and improves the DOL target logic.

Changes in v1.02:

Session DOL mapping:

Input parameters:

Status: Latest version with session-specific DOL and enhanced controls

Description: Version 1.04 is the most granular implementation, introducing session-specific DOL targets, where each Silver Bullet window targets liquidity for a specific trading session. It also adds switching between Silver Bullet sub-modes (fixed target vs. DOL-based), one trade per window rule, and improved stop loss management.

Changes in v1.03:

Session DOL positioning:

Stop loss implementation:

One transaction per window rule:

Input parameters:
