No, but it has to. Say you have a neutral day, with 1500 advances, 1500 declines, up volume 400,000 and down volume 400,000. Trin = 1.00
At 4:10 p.m. IBM or some other biggie reports news, and all of a sudden goes from being down to being up, and a bunch of other companies follow suit.
In the composite close, now there are 1525 advances and 1475 declines on a change of 25 stocks flipping to positive. Up/down volume stays at what it was at the 4 p.m. close.
All of a sudden, trin = 1.03 On 50 stocks, it is 1.07
It just isn't very consistent or logical, if you use formulas and look at changes in an oscillator closely from one day to the next.
You could use Yahoo figures, but if you miss a day you are out of luck.
BMI could have a problem with their satellite feed. Then there are bad ticks.
I'm not going to lose any sleep over it. |
