TICK一定要和TRIN结合用才有效

stockhq的观察是对的。
我用IB的5-min TICK, TRIN chart.
比如今天3:00pm左右850的高点，TICK进入了高于1000的extreme area，这时TRIN<1.0是个confirmation>1.0的话，就不是confirmation，多半3:30pm就趴窝了(i.e., throw back to the support line underneath)。
Bearish state正相反，TICK enters <-1000 extreme area, at this moment TRIN > 1.0 is a confirmation (of bear). Otherwise, likely throw up to the resistance line above.
