Create a EA MT4 pyramid with break even included

It's a semi-automatic EA, I enter manually most of the data

1) Lot size (for all trades, decimal number, enter manually)

2) Type of orders (choice, BUY STOP, BUY LIMIT, SELL STOP, SELL LIMIT)

3) At price (enter manually, example : 1.2550 if EUR/USD, 105.50 if USD/JPY)

4) Spacing between trades (enter manually, in pips, not decimal number)

5) Number total of trade (choice, 2 to 10 trades maximum)

6) Stop loss at (enter manually, in pips, not decimal number, for all trades)

7) Take profit at (enter manually, in price, for all trades)

8) Break even (choice, for all trade, or for all trade except last trade)

For example with EUR/USD at 1.2225 :

- Lot size : 0.15

- Type of order : BUY LIMIT

- At price : 1.2200

- Spacing between trades : 10

- Number of trades : 4

- Stop loss at : 100

- Take profit at : 1.2400

- Break even : for all trades except last trade

If the market go at 1.2200, it open the first trade, stop at 1.2100 and take profit at 1.2400

If the market go to 1.2210, it open the second trade, stop at 1.2110, take profit at 1.2400 and first trade at break even (no loss for the first trade)

if the market go to 1.2220, it open the third trade, stop at 1.2120, take profit at 1.2400 and second trade at break even (no loss for the first and second trade)

if the market go to 1.2230, it open the fourth trade, stop à 1.2120, take profit at 1.2400 and third trade at break even (no loss for the first, second and third trade)

if the market go at 1.2240, the EA not move at break even for the fourth trade, because the fourth trade is the last trade,

if i selected "for all trades", the EA move the stop loss at break even for the last trade when the market go at 1.2240

Important rule, if the market touch just one stop loss, it canceled other pending orders

Sorry for my bad english, i am a french trader, you can please provide the EA 's source code ? thank you
