I wrote in Quick Takes Pro yesterday that the JNK junk bond ETF scored a death cross as the 50-day average dropped under the 200-day average. A customer challenged my saying that there was no such cross on Stockcharts.com and it was not even close.
Hmmm, I thought. Well, not hmmm but this could be a problem. So, I downloaded eSignal’s data (my charting package) and plotted it in excel. Same chart that eSignal itself plotted. Then I drew the same chart in Barchart.com and Bigcharts.com and they both agreed with eSignal.
How many people use Stockcharts? Rhetorical question. The answer is plenty. Are they trading off this discrepancy? Trust nothing and if you can afford it, buy two systems.
Stockcharts, if you are reading this I used to do this sort of chart checking for a living for Tradecenter and then Knight-Ridder Financial (their buyer).
