I am trying to implement sentiment index into my strategy, but i'm having a little problem understanding the data.
At the moment I am seeing 3 different sentiment index values for the same time period.

For example lets take USD/JPY at close time on 08.11.2013 (this friday).

The value on the web is 80.48% to Buy and 19.52% to sell, so I am assuming there are 80.48% of long positions.

On Demo account value of SWFX sentiment index is 51.68, (according to api it is the percentage of open long trades)

On live account at the same time this value is 74.23.

As far as I understand these values should be the same, can someone please explain why are they different ?
