What is a Multi-Symbol Scanner in Pine Script v5? (Simple Meaning)
A multi-symbol scanner is a custom script that checks multiple markets at the same time and shows conditions like:
- Buy/Sell signals
- Trend strength
- RSI oversold/overbought
- Breakout confirmations
- EMA crossovers
- Volume spikes, etc.
Instead of switching charts manually, this script automatically scans multiple tickers simultaneously and displays results on your current chart.
Step-by-Step Guide: Build a Multi-Symbol Scanner in Pine Script v5
Below is the cleanest and simplest method to build a fast multi-symbol scanner.
Step 1: Define the List of Symbols
//@version=5
indicator("Multi-Symbol Scanner v5 – 2025", overlay=false)
symbols = array.from( "NSE:NIFTY", "NSE:BANKNIFTY", "NSE:RELIANCE", "NSE:TCS", "NSE:INFY" )
Step 2: Create the Scan Condition
Example: RSI below 30 (oversold condition)
scanCondition(sym) =>
rsiValue = ta.rsi(request.security(sym, timeframe.period, close), 14)
rsiValue < 30
Step 3: Loop Through Symbols & Show Results
var results = ""
for i = 0 to array.size(symbols) - 1 sym = array.get(symbols, i) condition = scanCondition(sym) status = condition ? "📉 Oversold" : "—" results := results + "\n" + sym + ": " + status
label.new(bar_index, high, text = results, style = label.style_label_left)
What This Scanner Does
- Scans all selected symbols every candle
- Applies RSI logic to each
- Displays the output in a clean formatted list
- Updates automatically
You can replace the RSI logic with:
- EMA cross
- MACD cross
- Breakout
- SuperTrend
- Volume strategy
- Custom Algo Logic
Pro Tips to Improve Multi-Symbol Scanners (2025)
✔ Use request.security() carefully
Keep your script light — avoid too many symbols + too many indicators.
✔ Use var variables
This improves memory usage and speed.
✔ Avoid repainting
Always use lookahead = barmerge.lookahead_on only when required.
✔ Keep the scanner simple
Complex scanners slow down TradingView heavily.
