Hi, I'm not entirely sure that I understand your question, but I'll try to give some pointers.
There are subtle differences between native javascript and angular expressions <https://docs.angularjs.org/guide/expression>. Importantly, angular expressions are forgiving. From the docs: - Forgiving: In JavaScript, trying to evaluate undefined properties generates ReferenceError or TypeError. In Angular, expression evaluation is forgiving to undefined and null. Put another way: If you have an object a, which has a property b a = {b:"foo"} Then *In Javascript:* a.b.c is undefined *As an angular expression:* {{a.b.c}} evaluates to nothing *In Javascript:* a.b.c.d will give you a TypeError *As an angular expression:* {{a.b.c.d}} evaluates to nothing So may want to consider putting {{query.results.quote.Volume}} as an angular expression to avoid the nasty if then else logic that you would have to write for every property to guard against error (if you were unsure if they existed).
