Still the same saying, all the increase is for better sales. If you haven't held at the bottom, it's not advisable to chase the highs. Those who entered halfway can consider reducing their positions or exiting, after all, what you have secured is yours. This refers to spot trading.

As for contracts, it is inherently dual-sided. Follow the trend; if the market is good, go long; if the market is bad, go short. There is still a significant difference between the two.
