On Friday the US futures sunk down lock-limit. Asia was crashing. You didn't cut rates. The US markets actually rose from their open but still closed down a hefty bit. You got lucky. Today, if the futures are down big again, you can't do the same. You must cut huge in order to restore what little credibility you have left. This is what the markets want you to do. If you don't, there is likely to be a crash. Don't make the same mistake twice.
