there is any option that i need to change at metatrader platform  ? again at back test its work

the send order quote 

ordershort=OrderSend(NULL,OP_SELL,optimallotsize(percentloss,Bid,stoplossshort),Bid,20,stoplossshort,takeprofitshort,NULL,magicNMshort);
      
if(ordershort<0)
      {
         Alert("order faild error = " + GetLastError());
      }

   That is because it is broken.
   

2. ordershort=OrderSend(NULL,OP_SELL,optimall…

   Be careful with NULL.

   1. On MT4, you can use NULL in place of _Symbol only in those calls that the documentation specially says you can. iHigh does, iCustom does, MarketInfo does not, OrderSend does not.
   2. Don't use NULL (except for pointers where you explicitly check for it.) Use _Symbol and _Period, that is minimalist as possible and more efficient.
   3. Zero is the same as PERIOD_CURRENT which means _Period. Don't hard code numbers.
   4. MT4: No need for a function call with iHigh(NULL,0,s) just use the predefined arrays, i.e. High[].

Thank you for your answer

soo every place that i worth "NULL" i need to change to "_Symbol" and every place i worth "0" i need to change to "_Period" ?

why at the back test its was work good despite i worth "NULL" and " 0 "

IF you are not getting any alert then obviously the OrderSend() is not being executed.

You should check the conditions that should execute the above block of code

All the conditions above the block  was ok

as i said, i check this trade with back test and the trade was  executed

No they are not.

Keith Watford:

No they are not.

so i ask again

why at the back test the trade was  executed and at the real time is not ?

to only reason i see its like the previos commant was that i use "NULL" insted " _Symbol" 

[Netanel Tanami]

"Doesn't work" is meaningless — just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires — meaningless.

Hi Nati2009,

I had the same issue with one of my accounts only to find out that my Broker blocked my account from using Expert Advisors.

Use the following code to see if you are allowed to use an expert advisor on your account.

bool AccountTradeExpert = AccountInfoInteger (ACCOUNT_TRADE_EXPERT);//Is Expert Advisor allowed on my account true/false?
Comment ("Is EA allowed:",AccountTradeExpert);
