open/close orders, from MT4 to MT5

[M N]

I have written an expert advisor in MT4 and I want to convert it to MT5. Everything seems to work except I can't open or close any orders. I used the function from the MT5 reference library:

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
input double Lots=...;




//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+

void OnTick()
  {
   MqlTradeRequest request;
   MqlTradeResult  result;
      request.action=TRADE_ACTION_DEAL; 
      request.symbol   =Symbol();                             
      request.volume   =Lots; 
      request.deviation=100;   
...
        request.order=order_id; 
      request.price    =SymbolInfoDouble(Symbol(),SYMBOL_BID);
      request.type     =ORDER_TYPE_SELL;  
OrderSend(request,result);
...
}

Thanks, I updated the message with the full code. The only thing missing is a few if statements and other variables declarations, but they should be fine. I just wanted to check if my open order code is not completely wrong or something. MT5 is a lot harder than MT4. I wasn't sure where to put the lines but I put them into the top of the Tick function for general things, then for whether it's a sell or buy, I put it before each sell and buy to change it, then send the order. Please let me know which part is wrong.

M N:

I have written an expert advisor in MT4 and I want to convert it to MT5. Everything seems to work except I can't open or close any orders. I used the function from the MT5 reference library:

        "MqlTradeRequest request;

        MqlTradeResult  result;

request.action=TRADE_ACTION_DEAL; 

      request.symbol   =Symbol();                              

      request.volume   =Lots; 

      request.price    =SymbolInfoDouble(Symbol(),SYMBOL_BID);

      request.deviation=100;

request.type =ORDER_TYPE_SELL;

OrderSend(request,result);"

"Lots" is the only parameter I use which is the volume. The code does nothing in the strategy tester though. I doubt that Lots is the error, but I am not sure how to check for errors either.

Do you know a super simple way to write the open order code please? I don't want to write 100 lines of code when in MT4 it was 1 line. I am looking for the simplest way. I don't have many parameters.

Thanks

Please post your code properly, so I can read it. Use the code button to insert code. Edit your original post, don't repost.
