Function for calculating static TP market price for all open orders by entering profit percentage

Hi all,

I need somebody to help me with writing a function for MT4 which will calculate TakeProfit market price for all open orders entering profit percentage, when profit of winning orders exceeds loss of losing orders.

For example, if I set 10% as input value, profit of open winning orders have to be 10% more than loss of open losing  orders.

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 percentage is 10%, I need to calculate TakeProfit market price when profit from open  winning orders exceeds loss of open losing orders for 10%.

function input parameter will be percentage, for example: 5 or 10 or 15.5 (%)

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

function need to iterate over all open orders and calculate TP market price.

Order swap and order commission must be taken into account in the calculation.

function will be used for open 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 calcTPFromPercentage(double percentage)
{
  return TPMarketPrice;
}
