Liquidity Sweep Detector
Paste OHLC price data (index, open, high, low, close). The tool finds recent swing highs and lows, then marks bars where price briefly breaks a level (e.g. wick through) but closes back and reverses—typical liquidity sweeps or stop hunts.

Price and levels
What is a liquidity sweep?
A liquidity sweep (or stop hunt) occurs when price briefly breaks a recent swing high or swing low—often with a wick—then closes back on the other side and reverses. Traders interpret this as institutions sweeping stops above highs or below lows before moving price in the opposite direction. This tool identifies such bars from your OHLC data.
How to use this detector
- Paste OHLC data: One bar per line, columns: index (or date), open, high, low, close. Comma- or tab-separated. Use "Load sample data" to try demo data.
- Swing lookback: Left/right bars to define a swing high (local max) or swing low (local min). Larger values find fewer, more significant levels.
- Sweep confirmation bars: Number of bars after the break that must stay on the "correct" side to confirm a sweep (e.g. after wicking above a high, close below and next bar(s) stay below).

All processing runs in your browser. You can paste data from any chart or export (e.g. CSV). The chart shows close price with swing levels (dashed) and highlighted sweep zones. Use it to spot potential stop hunts and liquidity grabs in your timeframe of choice.
Frequently asked questions
What is a liquidity sweep?
A liquidity sweep (or stop hunt) is when price briefly breaks a recent swing high or swing low—often with a wick—then closes back on the other side and reverses. Traders interpret this as institutions sweeping stops above highs or below lows before moving price in the opposite direction.
What OHLC format should I use?
Paste one bar per line with columns: index (or date), open, high, low, close. Use comma- or tab-separated values. The first column can be a bar index (0, 1, 2...) or a date string; the next four must be numeric open, high, low, and close prices.
What are swing lookback left and right?
These define how many bars to the left and right of a bar are used to decide if that bar is a swing high (local maximum) or swing low (local minimum). For example, with left=2 and right=2, a bar is a swing high only if its high is the highest among the 5 bars (2 left, itself, 2 right).
What is sweep confirmation bars?
After a bar wicks beyond a swing level but closes back (e.g. wick above a swing high, close below), this is how many following bars must stay on the "correct" side to confirm a sweep. For example, 1 means the next bar must also close below the swing high to confirm a sweep of highs.
