This is usually understood as a stop-hunt or liquidity grab, so it's logical that a lot of orders should be executed during this time. As regular users, we can check this by monitoring trading volumes during that period. So, I turn on the volume indicator on the chart, and it really does look like a sweep if you see that the volume increased as the price moved outside the range.

However, this doesn't necessarily mean that the price will reverse. Additional confirmations are still needed.
