While the US stock market is closed, pricing doesn't stop. More and more of my friends who trade with US stock brokers are starting to keep an eye on so-called "on-chain prices." "On-chain" generally refers to the US stock contract quotes on platforms like Binance and Hyperliquid. Some even go to great lengths to specifically check these prices. Their positions are still with their brokers, but they're already referring to these prices to plan how to manage their holdings in advance. In my opinion, this is information that professional traders find difficult to ignore. Especially for event trading. If news breaks over the weekend and your position is still open, waiting for the US stock market to open could result in a price gap. The NVDA incident is a prime example. After the negative news broke over the weekend, Binance NVDA perpetual contracts were already trading. According to the snapshot at the time, the contract index price was about 3% lower than the previous closing reference price. How the underlying stock will open next remains to be seen. However, even during the market closure, those willing to place orders have already made their intentions clear. Let's look at the NVDA contract comparison data from this weekend: Trading volume: Binance $360 million, second place $181 million, nearly double. Open interest: Binance $90.6 million, second place $57.8 million, approximately 1.6 times. In this comparison, Binance ranks first in both trading volume and open interest. With trading and open positions, these quotes naturally attract more attention. With weekend news, you can still adjust your contract positions or temporarily hedge your US stock holdings at your brokerage. Some traders simply look at the price, while others are already using it to manage risk. These contract quotes are entering the daily judgment of truly professional US stock traders. Binance also has a dedicated holiday price page where you can directly view price changes and trading activity. Many unexpected events occur outside of trading hours, and Binance will provide you with the best trading experience. News doesn't wait for the market to open, and trading doesn't have to either.
