What's wrong with ESignal's Bollinger Bands?

Attached is a screenshot of a 5min chart of CVC as an example. I'll also post a screenshot of the same chart using Investor RT.

As you can see, there is a dramatic difference in the calculation of the bollinger bands on the two charts. I'd like to know which of the two programs is calculating the bands correctly.

I pulled up the chart on QCharts and the calculation of the bands match Investor RT. Because of this, I'm assuming the problem is with ESignal.

Had to zip the file as it was too big to upload without compression.

Hi Derek,

Looking at the two charts, it looks like the chart of eSignal has been set to a 10 minute interval whereas the Investor RT chart has been set to 5 minute; which is most likely the reason for the difference. Please let me know if I'm correct in my comparison.

You're right. Doh! That was a dumb error on my part. Sorry about that.
