In order to limit 'wild whales,' Binance has also introduced price ranges. After the adjustment, wild whales can only clear out sell orders within the range and push the price to the upper limit of the protection zone, but they can no longer use a single order to eat up endlessly and instantly push the price to an absurd level. However, the reference price keeps changing. If the market has already been pushed higher, the reference price will move up accordingly, allowing new active buy orders to continue sweeping within the new price range. The main purpose is to prevent sudden, massive price spikes in an instant.
