Binance will introduce new spot trading limitations to avoid erratic trading. The key trading hub for multiple tokens is looking to avoid extreme volatility events.
Binance will introduce the Spot Price Range Execution Rule (PRER), gradually unrolling across multiple markets.
The spot exchange is still key during periods of volatile sentiment, with increased trading activity. This has led to multiple cases of erratic price discovery. The new rule has been integrated into the Binance API, and other apps will have to constantly monitor the reference price range.
PRER aims to prevent user orders from being executed at abnormal prices that are often seen during extreme market conditions. The orders will only be executed within a predetermined dynamic price range.
Binance to restrict spot trading under volatile conditions
The new feature arrives after Binance introduced an expanded liquidity program for altcoins. The additional safeguards may make Binance safer even in a market with some distrust of altcoins.
PRER will launch on April 14, gradually introduced to not disrupt trading. Under normal trading conditions, the mechanism will not affect price discovery.
The aim of PRER is to restrict orders to only execute when there is liquidity within a certain price range. If the price deviates significantly due to volatile trading, the orders will not be filled.
All taker orders with execution prices outside the dynamic liquidity range will expire and not be filled. This will protect the market from erratic price movements and flash crashes. Binance has seen multiple spot trades outside normal price ranges, usually dismissed as inherent to crypto.
Did Binance cause the October 10 crash?
Binance has so far denied it was at fault for the October 10 crash. The exchange operated similarly to other markets, and cited external conditions as the main cause for volatile trading.
The biggest problem was caused by the depegging of the USDe stablecoin. The stablecoin had no problem functioning on-chain, but on Binance, the asset fell from $1 to $0.65. The sharp price move caused a wave of redemptions and liquidations, ending up with $19B erased from the market.
Trading within a predetermined price range may prevent similar price moves, especially for stablecoin pairs. Orders at extreme price ranges, set up to benefit from errors, will not be filled under the new rules.
The PRER trading rule will not protect retail users from volatility entirely. It will only prevent some orders from being filled during events like a flash crash. The exact trading rules may change with time, and each traded symbol will have its own limitations and price range.
Binance currently carries most of its trading on the futures market, but spot price discovery is key for oracles and affects the wider crypto ecosystem.
