I looked at the rates, and almost all of them are negative, and the stronger the currency, the higher the negative rate... What does this indicate?

It actually means that those "gamblers" who used to chase after rises and leverage their positions to the max have been mostly cleaned out in last week's market.

In the current market, there are basically no new investors left; it's all experienced traders and high-level players who start hedging as soon as prices rise and wait for a pullback.
