down volume, and up OI,
lets say, first day 100 contracts trade, all 100 are cross trades,
one side of the contract is new position, other side is old postion, so change in
OI is zero. next day volume is 50 contracts trade, volume is DOWN, but
both sides are new long and new short so OI is UP +50.
Interpretation, ie bullish bearish? I am guessing you need to also look at the price...
since if the price was rising the down volume signal bear, but the up OI signal
bull, so overall mixed,
reverse the roles, for the case up volume, down OI.
hope others chime in with their interpretation and what else they look at when
doing analysis.
