AO moved to negative after yesterday

$NVIDIA (NVDA.US)$ looking at AO in correlation to price movement yesterday showed negative period starting today or tomorrow, looks like there was enough pressure to end the day in negative AO oscillation. this time as we touch and move negative we are much closer to the 90$ low experiences during a positive AO into negative, we are only 17$ from that 90$ point. we just got negative AO and price could go deeper than the 90$ experienced during the last drop. just my thoughts but if anyone cares to look they might be able to confirm my theory
