Function for calculating static TP price for all opened orders by entering money

Hi all,

I need somebody to help me with writing a function for MT4 which will calculate static TakeProfit price for all opened orders by entering money in account currency.

I need this function for my grid system EA

For example:

My EA opened 3 market orders in same direction (EURUSD symbol)

1. order - buy with 0,02 lots, opened at 1.17196

2. order - buy with 0,04 lots, opened at 1.16946

3. order - buy with 0,08 lots, opened at 1.16696

my TP money is 10$, I need to calculate TakeProfit price when profit from all 3 orders together will reach 10$

function input parameter will be money, for example: 10 (USD)

function return result will be TP price, for example above: 1.17112

function need to iterate over all opened orders and calculate static TP price.

function will be used for opened buy or sell orders in same direction.

I want to use this function in all of my future EAs, so I need all rights for it.

double calcTPAll(double money)
{
  return TPprice;
}
