Grid Trading with RSI and Fibonacci SL

This script implements a grid trading strategy that buys when the "AI" confidence is high and the RSI is oversold, and sells when the "AI" confidence is high and the RSI is overbought.
It uses a Fibonacci-based stop-loss and adjusts the grid levels and trade size after each trade.

The "AI" is a very simple rule-based system, not actual artificial intelligence. The script also plots the RSI, AI confidence, grid price, and stop-loss level on the chart.

It's important to thoroughly backtest and understand the risks associated with grid trading strategies before using them with real capital.
