Help MQL4 Program !

 
Hello All
I want to write a simple Moving average cross. It like EA demo.Can you help me ?
The Following are noteworthy :
Timeframe 1 hr Chart
Profit Target default = 25(should be a variable)
Stop Loss default = 10(should be a variable)
EMA=Exponential Moving Average
Buy Entry is above EMA when the price crosses above the EMA and is 21 pips
Sell Entry is below EMA when the price crosses below the EMA and is 21 pips
Variables shoud be inputs like in TS
Thanks!
