[Ahmed Atef]

i want to open buylimit or sellimit orders but at specific time only .

example : set buy limit order 1.10001 from 6 am to 9 am only after that cancel the order .

please check the code and give me the right code or correct it , please .

if((D'6:00:00'<= Time[0]<=D'9:00:00') == true)
      {
         double minstoplevel=MarketInfo(Symbol(),MODE_STOPLEVEL); 
   Print("Minimum Stop Level=",minstoplevel," points"); 
   double price=Ask; 
//--- calculated SL and TP prices must be normalized 
   double stoploss=NormalizeDouble(Bid-minstoplevel*Point,Digits); 
   double takeprofit=NormalizeDouble(Bid+minstoplevel*Point,Digits); 
//--- place market order to buy 1 lot 
   int ticket=OrderSend(Symbol(),OP_BUYLIMIT,0.1,h,3,stoploss,takeprofit,"My order",0,0,clrGreen);                     
         }
         else
            Comment("false");

1. if((D'6:00:00'<= Time[0]<=D'9:00:00') == true)

   D'6:00:00 is six AM of the  day you compiled. Not 6 today. Either use StringToTime or:

2. True = 1 and false = 0 so you get

   if( 3 < 2 < 1 ) if( false < 1 ) if(     0 < 1 ) if(     true  )	if( 3 > 2 > 1 ) if(  true > 1 ) if(     1 > 1 ) if(     false )

3. You should be able to read your code out loud and have it make sense. You would never write if( (2+2 == 4) == true) would you? if(2+2 == 4) is sufficient. So don't write if(bool == true), just use if(bool) or if(!bool). Code becomes self documenting when you use meaningful variable names, like bool isLongEnabled where as Long_Entry sounds like a trigger price or a ticket number and "if long entry" is an incomplete sentence.

4. double stoploss=NormalizeDouble(Bid-minstoplevel*Point,Digits);

   Do NOT use NormalizeDouble, EVER. For ANY Reason. It's a kludge, don't use it. It's use is always wrong
   • SL/TP (stops) need to be normalized to tick size (not Point.) (On 5Digit Broker Stops are only allowed to be placed on full pip values. How to find out in mql? - MQL4 and MetaTrader 4 - MQL4 programming forum) and abide by the limits Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial and that requires understanding floating point equality Can price != price ? - MQL4 and MetaTrader 4 - MQL4 programming forum
   • Open price for pending orders need to be adjusted. On Currencies, Point == TickSize, so you will get the same answer, but it won't work on Metals. So do it right: Trailing Bar Entry EA - MQL4 and MetaTrader 4 - MQL4 programming forum or Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 and MetaTrader 4 - MQL4 programming forum
   • Lot size must also be adjusted to a multiple of LotStep and check against min and max. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.

5. double takeprofit=NormalizeDouble(Bid+minstoplevel*Point,Digits); 
   //--- place market order to buy 1 lot 
      int ticket=OrderSend(Symbol(),OP_BUYLIMIT,0.1,h,3,

   Using Points means code breaks on 4 digit brokers, exotics (e.g. USDZAR where spread is over 500 points,) and metals. Compute what a PIP is and use it, not points.
