Upgrading EA with 2 new variables

Hi everyone!
I have a working EA based on SMAs and need someone to code the following,

A. Conditions
- The programmer must allow me to do backtesting before making the payment.
- Upon payment, the programmer must provide the .mq4 file.
- The .mq4 file must compile without any "Warning".
- The EA will be tested and used on ICMarkets raw account using MetaTrader 4.
- The intellectual property of the EA belongs to the contractor.
- The programmer has no responsibility for the effectiveness of the EA.
- The EA must only place one order (BUY or SELL) at a time.
- The EA must be capable of backtesting on the following pairs - EURUSD,GBPUSD,USDCAD,EURGBP,EURAUD,AUDCAD,AUDUSD,EURCAD,NZDUSD,AUDNZD.

B. Required Coding (please adapt as required)
1. When placing a BUY order, I wish to retain the price at which the order was placed - variable "initial_price_buy" (e.g. using iOpen);
2. When placing a SELL order, I wish to retain the price at which the order was placed - variable "initial_price_sell" (e.g. using iOpen);
3. When closing a BUY, besides the provided SMA logic, the order will only close if "close_buy" is ABOVE " initial_price_buy ";
4. When closing a SELL, besides the provided SMA logic, the order will only close if "close_sell" is BELOW " initial_price_sell ";

NOTE
I've attempted to code items 1,2 and 3 above but could not manage. My code is commented in the sample code I'm attaching and is provided in the following lines..
24;25;26;27;63;64;65;66;88;93;99 and 108.
