ONLY CANDLE / BAR - How to catalog or segregate Candle? - PLEASE CORRECT ME! - page 4

I have a feeling we lose a little bit control over the code....

 

        if ( SignalBULL62Executed) CheckForClose_BULL6();       // I don't know it is the right place to close

No, this is for sure not the right place.

 

   int    result;
   if(Bid==Close[1]+3*Point)  
     {
      result=OrderSend(Symbol(),OP_BUY,0.61,Ask,0,Close[1]-25*Point,0,"",MAGICMA2,0,Red);
      return;
     }
   if (result == -1)
      {
      int e = GetLastError();
      Print(e);
      }   
  } 

This 'error handling' does not make anything better. Check it again.

 

bool Fun_New_Bar()                              // bool             

   {                                
   static datetime New_Time=0;      
   New_Bar=false;                   
   if(New_Time!=Time[0])           
      {
      New_Time=Time[0];                
      New_Bar=true;                    
      }
   }

This is not created for fun! It should be used to reset the executed flags on a new bar.

 

if(Bid==Close[1]+3*Point)  

What have we learned about comparing doubles and whether this makes any sense here?

So you have decided to delete your post I am referencing to... Well done, that's very helpful !

Sorry but yesterday was problem in internet (mql4.com stop working). I was try correct something and ...  collapse

It is not easy to help you. Why won't you try to implement only one strategy for now, but with a proper, Open(), Close(), Count(), NewBar(), Signal() function.

The below block is outside of the start function. I am not sure this is wanted.

Fun_New_Bar();
if (New_Bar==false);               // <-- ???
bool SignalBULL41Executed=false;   // <-- This could be correct, but I am not sure you know why and
bool SignalBULL42Executed=false;   //     its not more an accident that you initalize it here.
bool SignalBULL61Executed=false;
bool SignalBULL62Executed=false;
bool SignalBULL63Executed=false;

if(Fun_New_Bar())                  // <-- Your Fun_New_Bar() function doesn't return anything,
{                                  //     you set the global New_Bar variable with the function. 
   SignalBULL41Executed=true;      // <-- You should set it to false on a new bar.    
   return(SignalBULL41Executed);   // <-- ???
}

I think the same as You, small steps. Let's take just one option BULL4
Sometimes looking like Ea to my on codebase

https://www.mql5.com/en/code/9156 - interesting

I understand these (but not feel), i'ts a flag and I understand its purpose

Yes, small steps, so the errors are manageable...
Do you want to highlight something specific from the codebase EA?

I wont see this again - I will not help you anymore if you further ignore the correction steps, I - or someone else - has adviced to do:

if( Bid==Close[1]+3*Point)

 

Slippage is 0? You'll probably get an error. But the fixed error handling will catch it :-)

result=OrderSend(Symbol(),OP_BUY,0.41,Ask,0,Close[1]-25*Point,0,"",MAGICMA1,0,Blue);

 

This is not wrong, but not ideal and in a worst case it does not what you want inside the loop. Best, don't even start using loops from 0 to OrdersTotal. Read this: Loops and Closing or Deleting Orders

for(int i=0;i<OrdersTotal();i++)

 

What is your brokers spread and how many digits do you have for the symbol you want to trade? I am not sure you use Point correctly (Read on the first page of your thread). 

You can't NormalizeDouble() a bool,  the clue is in the function name and in the documentation too . . .  

double NormalizeDouble( double value, int digits)

It's a pitty we cannot normalize true to be very true :-(

 

No, you don't have to normalize Bid or Close[1]. What I meant is, you should just not compare it for equality.

Imagine: 
Close[1] = 1.31933
New_Bar
Tick1, Bid = 1.31935
Tick2, Bid = 1.31934 
Tick3, Bid = 1.31937
Tick4, Bid = 1.31937
Tick5, Bid = 1.31942 

Your code does look for a Tick where Bid is 1.31936  

if( Bid==Close[1]+3*Point)

You'll miss your signal. This would not happen, if you use > . 

 

This doesn't make it much better. All your calculation in Points should be Pips from my understanding. However, I have no experience with ECN brokers, so it might work.

 

Agree and there are many very good articles more, written by the same author. Also the book is not a bad place to start.

 

On your brokers website is stated, that for EURUSD, the minimal spread is 0,1. The average spread is 0,5. <-- This is meant in pips! So 0,1 is 1 Point. 0,5 is 5 Points.
So in your case, one Pip is 10*Point. The spread will confuse all your mini calculation where you add only 3 points to a price.
Search for 'adjust for 5 digit broker' and you should find a lot of examples.

HI :)

 

If this code was bad because I was passing signals, it has improved. I thought that the problem is entirely in a different place, not in the sign of equality '=='.........    the '>=' is better idea of course

if( Bid==Close[1]+3*Point)

if( Bid>=Close[1]+MyPips*3)

 Question 1. Do I have use MyPips in candle, in these function? bool BULL4()

 

DIGIT problem.

I found these 

https://www.mql5.com/en/forum/140097    by WHRoeder

https://www.mql5.com/en/forum/123736  by WHRoeder

What is Digit ? in https://docs.mql4.com/predefined/variables/digits  and  https://docs.mql4.com/convert/doubletostr

Because you are the expert I should have said something, it might be important.
Now I use the MT4 platform and I see 4 digits after the decimal point (Bid-Ask = 0.0001 usualy). At the moment we programmed in MQL4 let it be.
In MT5, I see 5 digits after the decimal point. threre is differs betwen MQL4 and MQL5. At the moment this spreed does not matter to me. Important to our EA worked well.
I do not want at this time to talk about it (unless necessary)

 

 

AND I WROTE PROGRAM for me is good :) how about You?
