Sweep Indicator TradingView: Detect Smart Money Liquidity Grabs
I've watched ES futures sweep above a swing high at 10:30 AM, trigger a cascade of stop-losses, and drop 40 points in two hours. A sweep indicator is a Pine Script tool that flags these liquidity grabs — when price breaks a swing point but can't hold, then reverses hard. It scans 1000 bars back, identifies swing highs and lows, and marks a bearish sweep when price closes above a swing high but closes back below it. A bullish sweep fires when price dips below a swing low but recovers above it on the same bar.
This indicator changed how I read charts. Instead of chasing breakouts, I wait for the sweep and position for the reversal. After running it on BTC/USD on the 1-hour chart from October to December 2025, I caught 7 out of 11 major sweeps that led to reversals of at least 2%. I prefer using it on 15-minute and higher timeframes — anything lower generates too many false signals for my style. I haven't tested it on low-liquidity altcoins or exotic forex pairs, so I can't vouch for those markets.
