Here is a little trick for opening orders for the loyal fans:
Look at the prices of spot and perpetual USDT and Yue. If the spot price is lower than the perpetual price, the market is basically bullish. When the market is bullish, Heyue is basically at a positive premium.
On the contrary, if the spot price is always higher than the perpetual price, the larger the price difference, it means that the overall trend is still bearish.
When it is almost flat, you should pay attention to whether the market has reversed.
