Ubuntu touch: Change: %s

[Hannie Dumoleyn]

Could anyone tell me what is meant by the word "Change" in ubuntu-rest-scopes #220 and #221?
Change: %s
Located in
     src/scopes/yahoofinance.py:257
%% Change: %s

I found this in the code:
# Content for the text widget
             text_for_values  =  []
             text_for_values.append(
                 translator('Price:%s'  %  result['value'],  locale))
             text_for_values.append(
                 translator('Change:%s'  %  result['change_v'],  locale))
             text_for_values.append(
                 translator('%%  Change:%s'  %  result['change_p'],  locale))

Thanks for helping me on this,
Hannie
