$IR Key Practical Reference: When rebounding to positions 0.208, 0.228, if the trading volume does not increase, it may stagnate, and one can reduce their position; if the volume can stabilize above 0.247, a small position can be attempted to go long, with a target of 0.263; once the support at 0.174 is broken, decisively stop-loss and exit to avoid further downside risk.

As for the current market, be cautious of a second retest.
