Hello, can anyone tell me why my ordersend function wont execute? 

Where do you open your first order? I'm asking because in the code u posted, a first order is expected, before any further orders can be opened.

Now, assuming that you have the first order, then can you do a Print(GetLastError()) right after your OrderSend() function and let us know the error code?

Also, please use the code icon when you include codes:

1. Why did you post your MT4 question in the Root / MT5 General section instead of the MQL4 section, (bottom of the Root page?)

   Next time post in the correct place. The moderators will likely move this thread there soon.

2. When you post code please use the CODE button (Alt-S)! (For large amounts of code, attach it.) Please edit your (original) post.

4. int ticket=OrderSend(Symbol(),OP_SELL,LotSize,Bid,3,OrderStopLoss(),OrderTakeProfit(),NULL,0,0,NULL);

   You would know why (lack of error code means № 3 or you are not even calling the function,) if you check your return codes for errors, and report them including GLE/LE. Don't look at it unless you have an error. Don't just silence the compiler, it is trying to help you.

   Only those functions that return a value (e.g. iClose, MarketInfo, etc.) must you call ResetLastError before in order to check after. 

5. You have an open buy order (assuming not № 3,) therefor any SL must be below market and any TP is above. How can you open a sell order with the same stops? You would know this if you had checked (№ 4)

6. You didn't set your profile, but Since 2009, hedging is not permitted for US traders.

7. vbid==OrderStopLoss()

   Doubles are rarely equal. Understand the links in:
             The == operand. - MQL4 and MetaTrader 4 - MQL4 programming forum

8. double vbid= MarketInfo (Symbol(),MODE_BID);
   
   double vask= MarketInfo (Symbol(),MODE_ASK);
   
   double StopLoss= OrderStopLoss();
   
   double openprice= OrderOpenPrice();

   1. These are globally declared variables, they are initialized once on load. They don't update unless you assign to them.
   2. Don't try to use any price or server related functions in OnInit (or on load,) as there may be no connection/chart yet:
      1. Terminal starts.
      2. Indicators/EAs are loaded. Static and globally declared variables are initialized. (Do not depend on a specific order.)
      3. OnInit is called.
      4. For indicators OnCalculate is called with any existing history.
      5. Human may have to enter password, connection to server begins.
      6. New history is received, OnCalculate called again.
      7. New tick is received, OnCalculate/OnTick is called. Now TickValue, TimeCurrent, account information and prices are valid.
   3. You can not use any Trade Functions until you first select an order.
