Watchlist Screener - NASAlgoTrading

The Watchlist Screener - NASAlgoTrading indicator provides a centralized dashboard to monitor market bias and trend signals for up to 10 customizable symbols from a single chart. It utilizes a dual Exponential Moving Average (EMA) crossover logic to categorize assets into Bullish, Bearish, Long, or Short states, helping traders track multiple instruments efficiently without switching timeframes or tabs.

Usage

The Usage section focuses on how to interpret the dashboard and configure the symbol tracking. The script is designed as a companion tool for trend-following strategies, specifically those looking for momentum shifts.

• Interpreting Signals: The screener prioritizes the most significant price action. A "Long" or "Short" signal indicates a crossover has occurred within the last 4 bars. If no recent crossover exists, the tool displays "Bullish" or "Bearish" based on the current EMA stack.
• Symbol Configuration: Users can input any valid ticker (Forex, Crypto, Stocks) into the 10 available symbol slots. The "Max Symbols to Display" setting allows users to trim the table size to match only the active tickers they wish to monitor.
• Visual Integration: The table can be moved to any corner of the chart to avoid overlapping with price action. Color-coding provides immediate visual feedback: bright green/red for active signals and muted yellow/orange for established trends.

Details

The script executes calculations using request.security to fetch data for external symbols. The core logic relies on two Exponential Moving Averages (EMAs).

• Logic Hierarchy: The status is determined in the following order: Long > Short > Bullish > Bearish.
• Recency Filter: To ensure traders do not miss momentum shifts, "Long" and "Short" signals are held for a lookback period of 4 bars after the initial crossover.
• Conditionals:
  • Bullish: Fast EMA > Slow EMA.
  • Bearish: Fast EMA < Slow EMA.
  • Long: Fast EMA crosses over Slow EMA within the last 4 bars.
  • Short: Fast EMA crosses under Slow EMA within the last 4 bars.
