Summation Index
It looks like something I should track more closely but one red flag stands out. Every day I pull down A/D data from the NYSE yet it's different data depending on where you get it. Every source I check is different from the next. The last time I checked I went to the NYSE, Yahoo, BMI, PC Quote, Pinnacle and Reuters and they were all different.
Pinnacle, as a matter of fact, often changes it from last night to this morning for example. I usually wait to download data from Pinnacle until the morning and there is usually a "flag" that tells tells me that the A/D numbers, A/D volumes, New Highs, New Lows and so forth have changed overnight.
Not such a big deal on a daily basis but cumulatively the net change can be extreme. On the other hand, as long as the Osc is consistent with regard to the source of the data I imagine it's not such a major glitch.
