Martingale code

Hi,

I need a code to work like below:

I need to set manually an OCO pair BUY/SELL order with fixed TP/SL.

After any of pending order get activated, the code has to work automatically. 

When a BUY order is closed at Stop Loss, a new SELL market order is opened at a double amount of the just closed order with the same SL and TP in PIPS like just closed order.

When a SELL order is closed at Stop Loss, a new BUY market order is opened at a double amount of the just closed order with the same SL and TP in PIPS like just closed order.

When any order is closed at TP, than it has to do nothing.

For any opened/closed order I need to receive an email.

How much does it cost? 

Thank you.
