simple EA need help to program

hi i'm a new EA programmer,
need help to create an EA

rules:
1. average price = (previous day high + previous day low)/2
2. resistance = average price + 20
3. support = average price - 20
4. if running between support and resistance, order sellstop @ support and buystop @ resistance with SL @ average price and TP 30pips, expired on next day
5. if one of the stop order is done, cancel other
6. repeat if price running back between support and resistance, and there's no open position

thanks for your HELP!!!

If you're an EA programmer, you might learn best by trying to write your code first and then building it by help. Otherwise, you'll never really learn and always depend on free code
