Getting avg sub aggregation

I'd like to get the avg of a sub aggregation. For example, i have daily profit of each branch. I want to sum them so that i can get total daily profit. and then i want to get the monthly or week average of that daily profit. So far i have done this

{
    "size" : 0,
    "aggs" : {
        "group_by_month": {
          "date_histogram": {
            "field": "Profit_Day",
            "interval": "month",
            "format" : "MM-yyyy"
          },
          "aggs": {
                "avgProf": {
                    "avg": {
                        "field": "ProfitValue"
                    }
                },
                "group_by_day": {
                    "date_histogram": {
                        "field": "Profit_Day",
                        "interval": "day",
                        "format" : "yyyy-MM-dd"
                    },
                    "aggs": {
                        "prof": {
                            "sum": {
                                "field": "ProfitValue"
                            }
                        }
                    }
                }
            }


        }
    }
}

Issue is i am getting daaily sum which is correct but instead of getting monthly average of daily sum i am getting monthly average of profit from each branch.

{
  "size": 0,
  "aggs": {
    "group_by_month": {
      "date_histogram": {
        "field": "proffit_day",
        "interval": "month",
        "format": "MM-yyyy"
      },
      "aggs": {
        "group_by_day": {
          "date_histogram": {
            "field": "proffit_day",
            "interval": "day",
