HELP!!!

Alright, I've put together a strategy that is supposed to buy at the open of the next bar when the previous bar's Close > Open. The trade ends either at my stop/limit or when the Close < Open (if I haven't hit my stop/target, my trade should end at the open of the down close). I cannot get this code to compile correctly, any advice?

this code can't even pass compilation https://www.mql4.com/files/MQl4BookEnglish.chm

  
double firstStartSignal = iClose("EURUSD", PERIOD_M30, BarShift);
double secondStartSignal = iOpen("EURUSD", PERIOD_M30, BarShift);

double firstEndSignal = iClose("EURUSD", PERIOD_M30, BarShift);
double secondEndSignal = iOpen("EURUSD", PERIOD_M30, BarShift);

if(Close[BarShift] > Open[BarShift])
   double UseLow = iLow(NULL, 0, BarShift);

Initialize variables with constants outside of start. non-constants must be inside.

what is the value of UseLow when the if() is false.

If Close[BarShift] < Open [BarShift]) then the UseLow variable then my wish is to not implement the BarShift variable. Should I add this as an "else" statement?

BarShift is supposed to be designed to shift to a bar other than the current bar to analysis. Thoughts?

 
Does anyone have an answer? Thanks!
 

It looks like you are missing a few closing brackets.

For this one: 

{
               OrderSelect(SellTicket, SELECT_BY_TICKET);

and this one:

{
            OrderSelect(BuyTicket, SELECT_BY_TICKET);
