Use a switch command.

switch (OrderType())
{
case OP_SELL:

break;

case OP_BUY:

break;
}

Marco vd Heijden:

Use a switch command.

Thanks for the comment, I will try it soon.

You can also use #define directive if you want to simplify things even further:

#define buy OP_BUY
#define sell OP_SELL

if(OrderType()==buy)

if(OrderType()==sell)

I already use #define which one it is copied for pip and point codes from Mr. William.
So after your comment I just a bit researched about it, I think I can use it in my any scripts.

Thanks for your useful comment.

Thanks a lot man.

I am first time trying Switch Operator for my this EA's.
So I would like to say I was learned a bit more about this, but I have not experience for this operator.

Before I try it in my test EA's I just need to ask, you mean I could use like below code, please? ( my test ea's already have 500 lines - and I am going to confused for OrderType() converting to string )

for ( ... )
{
    switch ( OrderType() )
    {
        case    0  :    ObjectCreate( ... name + " Buy" ... );
                        ObjectSetInteger(chart_ID,name + " Buy",OBJPROP_COLOR,clr);
                        // ...
        break;
        case    1  :    ObjectCreate( ... name + " Sell" ... );
                        // ...
        break;
    }
}

Thanks in advance.

Maybe my concern not clearly.
I already spent a lot of time for this issue I really playing this operator, but not result.

Below code gives me numeric.

Print( "OrderType: ", IntegerToString( OrderType() ) );

// EURAUD,M30: OrderType: 0

But I try to get below result.

// EURAUD,M30: OrderType: Buy

Just I need useful comment.
Can you help me ( / give me advice ), please?

Assignment and initialization, expressions Break jump Data types and values

Marco vd Heijden 2017.01.04 07:33 #187

ID	Value	Description
OP_BUY	0	Buy operation
OP_SELL	1	Sell operation

    switch(OrderType())
     {
      case 0:
       Print( "OrderType: buy" );
      break;

      case 1:
       Print( "OrderType: sell" );
      break;
     }

or

   if(OrderType()==0)
     {
      Print("OrderType: buy");
     }

   if(OrderType()==1)
     {
      Print("OrderType: sell");
     }

Thanks a lot @Marco.

Finally I got it, but I was expecting I would write code one of " Conversion Functions "... my wrong expectation was confusing me.
At this time, I am using 3 " HLine " objects, now I copied that for both cases ( 0 and 1 ). It works good so far.
Also " Order Properties " have 6 values, so I would like to apply same ( e.g object, color, style, width and so on... ) Print function to 0, 2, 4.

Q: Could I use below method?

( Print function just for example )

switch ( OrderType() )
{
    case 0: Print( "OrderType: buy" );
            // ...
    break;

    case 2: Print( "OrderType: buy" );
            // ...
    break;

    case 4: Print( "OrderType: buy" );
            // ...
    break;
}

Thanks a lot in advance!

Any questions from newcomers help needed with too Series Array will not

Marco vd Heijden 2017.01.04 12:34 #189

No because the values are:

ID	Value	Description
OP_BUY	0	Buy operation
OP_SELL	1	Sell operation
OP_BUYLIMIT	2	Buy limit pending order
OP_SELLLIMIT	3	Sell limit pending order
OP_BUYSTOP	4	Buy stop pending order
OP_SELLSTOP	5	Sell stop pending order

So case 2 and case 4 are not equal to OP_BUY

They are OP_BUYLIMIT and OP_BUYSTOP so they are different things.

Unless this is what you mean but it would clarify to say

switch ( OrderType() )
{
    case 0: Print( "OrderType: buy" );
            // ...
    break;

    case 2: Print( "OrderType: buy Limit" );
            // ...
    break;

    case 4: Print( "OrderType: buy Stop" );
            // ...
    break;
}

After your latest comment I feel I can't combine case's 0, 2, 4.
Thanks @Marco vd Heijden for your time and your helps.
