Calculating percentage growth on Nested Fields

Elastic Stack Elasticsearch
1

Hi All,

I would like to calculate, fastest growing company(each document is a company) in Germany for the year 2016 with the below formula,
(New value - original value)*100/original value
I have below structure in my ES index,

 {
	"allData": [{
			"currency": [{
				"pAndL": {
					"netSales": 59955
				}
			}],
			"stmtDate": "2015-03-31",
			"isLatest": true
		},
		{
			"currency": [{
				"pAndL": {
					"netSales": 63134
				}
			}],
			"stmtDate": "2014-03-31"
		}
	]
}

From the above structure New value will be netSales where isLatest is true and original value will be netSales from other object.
Along with the above two object sometimes I may contain more than two objects.
Could someone please help me on writing Elasticsearch query for fulfilling this requirement.

Thanks,
Ram
