Three Scenarios Tonight

(1) Powell releases a clear signal that there will be a rate cut in September, which would be positive, sounding the horn for a counterattack, probability 20%

(2) Powell says it is not appropriate to cut rates now, but slightly hints at a future rate cut, which would also be positive, probability 50%

(3) Powell shows no willingness to signal any rate cut expectations, and even strengthens hawkish sentiment, which may lead to another drop, probability 30%

Rationally speaking, observe first. If it's spot trading, then gradually buy the dips; for contracts, only take needle-insertion trades while waiting for a reversal in the situation.
