issue with data coming back from quote service

[davpin]

at specific times of day, the UI displays nothing and curling the UI gives the following error:
{"timestamp":1452867880919,"status":500,"error":"Internal Server Error","exception":"org.thymeleaf.exceptions.TemplateProcessingException","message":"Error formatting decimal with minimum integer digits = 0, thousands point type = COMMA, decimal digits = 2 and decimal point type = POINT (fragments/marketsummary_fragment:67)","path":"/"}

Seems to suggest there is something wrong with the data passed to the UI.
