Chess Game

🧠 Concept

This script is an experimental chess game simulation built entirely in Pine Script, rendered as an overlay on a trading chart. It does not support interactivity like mouse clicks or real-time move detection, but instead relies on manual inputs to simulate moves and visualize board state.

This was created purely for educational purposes—to test the creative boundaries of Pine Script and explore how far visual scripting can be pushed within the limits of a financial charting tool.

🎯 Goals

Render a full 8×8 chessboard with labeled rows (1–8) and columns (a–h)

Display all pieces using Unicode chess symbols

Allow users to simulate moves using manual input

Validate basic move legality

Display turn status, current move, and instructions

🔧 How It Works

Chessboard Rendering

Uses tabel.new() to display 64 tiles and corresponding pieces.

Light and dark squares alternate based on standard chessboard layout logic ((row + column) % 2).

Pieces

All pieces (white and black) are placed at their initial positions using Unicode characters:

♙ ♖ ♘ ♗ ♕ ♔ for White

♟︎ ♜ ♞ ♝ ♛ ♚ for Black


⚠️ Limitations
Pine Script is not a general-purpose programming language. This game is non-interactive and must be controlled using input.int() and input.bool() for every move.

No click or drag-and-drop functionality.No timers, clocks, or multiplayer.No automated check/checkmate detection (yet!).No visual indication of selected squares (though that could be added with color-coded highlights)

📌 Why I Built This

TradingView is made for charting markets, but I wanted to see how far I could stretch it. Chess is grid-based like many financial charts, so I challenged myself to bring chess logic into Pine Script just for fun and learning.
