Simple BuyandSell Signals

This script is an original SuperTrend-based buy/sell signal indicator, designed to give clear, visually intuitive trading signals. It improves upon traditional Supertrend logic by adding trend highlighting, signal markers, and enhanced ATR handling.

🔹 Originality & Improvements

Combines a fixed ATR-based trend system with clear uptrend and downtrend highlighting.

Includes buy/sell labels and markers at trend reversal points for easy identification.

Highlights trends with semi-transparent fills for visual clarity.

Modified trend logic ensures consistent signals while avoiding repainting issues.

🔹 Fixed Parameters for Consistency

ATR period, multiplier, source, and trend highlighting parameters are all fixed.

Users cannot adjust these settings, ensuring consistent signals across all users.

🔹 Usage / Trade Guidance

Red line (Up Trend) → Consider entering long (buy) positions.

Green line (Down Trend) → Consider entering short (sell) positions.

Add-on / Scaling logic:

If price touches the red line but does not break below it, consider adding to long positions.

If price touches the green line but does not break above it, consider adding to short positions.

Suitable for multiple timeframes, swing trading, or as a filter for intraday setups.

🔹 Advantages

Reduces false signals with fixed ATR and trend logic.

Provides clear, visually intuitive trend signals.

Includes built-in alert conditions for trend changes and buy/sell events.
