              "date": "8/1/2018",
              "open": "8300",
              "high": "8325",
              "close": "8300",
              "low": "8200",
              "volume": "17178400"
            },

            {
              "symbol": "ASII",
              "date": "4/1/2018",
              "open": "8075",
              "high": "8225",

            },
            {
              "symbol": "ASII",
              "date": "3/1/2018",
              "open": "8250",
              "high": "8250",
              "close": "8050",
              "low": "8000",
              "volume": "40976100"
            },
            {
              "symbol": "ASII",
              "date": "2/1/2018",
              "open": "8300",
              "high": "8400",
              "close": "8200",
              "low": "8150",
              "volume": "24661300"
            }
            ...
    ];
    
    var result = changer(eodData,1, 3); 
    

    Output should be in 3 days duration data.

    Notes

    • Input data array should be sorted by date & time. New data on top.

    • It is possible to modify summarizer function, by passing the following object into the function

      var summarizer = [
                      {
                          fieldName: "high",
                          method: "max"
                      },
                      {
                          fieldName: "low",
                          method: "min"
                      },
                      {
                          fieldName: "date",
                          method: "first"
                      },
                      {
                          fieldName: "open",
                          method: "first"
                      },
                      {
                          fieldName: "close",
                          method: "last"
                      },
                      {
                          fieldName: "volume",
                          method: "sum"
                      }
