Bitcoin Momentum Strategy RSI(5) > 70

This script implements a momentum-based Bitcoin strategy using a single indicator: RSI (Relative Strength Index). The logic is simple yet powerful: it enters a long trade when RSI crosses above a certain threshold, signaling strength, and exits when momentum weakens.

🔍 How It Works
Buy Entry: RSI crosses above the Overbought Level (default: 70) and no position is open.

Exit: RSI drops back below the Overbought Level.

This strategy is designed to ride short-term bullish momentum on the 1D timeframe for BTCUSD.

All logic is handled using Pine Script v5 with fully adjustable input parameters.

🛠 Customizable Inputs
RSI Period: default 5

Overbought Level: default 70 (entry/exit trigger)

Oversold Level: default 30 (used for visual cues)

📊 Visual Enhancements
RSI line is green above Overbought (bullish), red below Oversold (bearish), and yellow in between.

Overbought/Oversold zones are marked with dotted lines and subtle background fill for easy chart reading.

⚠️ This strategy only takes long trades. It does not use any stop-loss or profit target logic and should be combined with sound risk management.
