Code for Buy Limits?

I am trying to set buy limits based on a percentage of the entry price. Does anybody know the code to do that?

For example, if I enter long at 1.2500 and I want a buy limit to be set automatically at 110% below the entry price, what code would be used to accomplish this?
Thanks

"if I enter long at 1.2500 and I want a buy limit"
You mean buy at 1.2500 and take profit at 110% from 1.2500.

If so : You set you TakeProfit to be

 

1. Bid * 1.10

Easy as that, Or you can use :

1. Bid + (Bid * 10 / 100)*Point

so you get you 10% profit

Make sure you have enought between TakeProfit and entry, since many broker ask a minimum pip TP (Ex.: InterbankFX ask minimum 5pips diffence)

If you mean set a buy limit at entry 1.2500 and TP 110%
Its the same anyway...

1. (Entry you want) * 1.10

Ex.: OrderSend(symbol,OP_BUYLIMIT|OP_SELLLIMIT,volume,1.2500,1.2500*1.10,etc...

Thank you for your reply. What I wanted to do was set up the buylimit to enter based a percentage or a factor of the entry price.

If the entry worked out to be 1.2500 I would want to divide that by 1.008 to get the buylimit entry price of 1.2401 if I carry the decimal 4 places.

Is there a variable that means entry price or is there some function I need to run in order to declare a variable as the entry price with out manually entering it?

I think I understand the rest of the code you gave me.

Thanks

A little addon for sell limit:

its not 1.2500 * 1.10 , or you will get 1.2500 +10%, it should be 1.2500 - ~10%

You must substract for selllimit

so Buy limit is

 

1. Bid + (Bid * 10 / 100 )

Ans Sell limit

1. Ask - (Ask*10/100)

Also its a bit weird!!!!
1.2500 * 10 / 100 = 0.125 so 1.25+0.125 = 1.3750
How could you get 1250 pip ? its hard to get 100pip so 1250pip ;-) Sorry my mistake.

I think it will be more
Buy Limit:

1. (EntryPrice + (EntryPrice * Percentage * Point))-> 1.2500*10*Point = 1.25 + 0.00125 = 1.25125

Sell Limit

1. ((EntryPrice - (EntryPrice * Percentage * Point))-> 1.2500*10*Point = 1.2500 - 0.001255 = 1.24785

If you want to place 1.2401 at the same time you place your order you do it manually.

1. Use 'Ask' for current ask price
2. Use 'Bid' for current bid price

But if the order is already place, then you do this....

1. Use 'Point' if you need it to get currency decimal 4 give =0.0001 and 2 give 0.01 ( 0.0008 = Point * 8pip)
2. When you have done your Order
   1. you use OrderSelect(...) to get the order
   2. then OrderModify(...) to modify the order
   3. and when you modify you use OrderOpenPrice(), OrderTakeProfit(), etc...

OrderOpenPrice(), OrderTakePRofit and other use current selected order to get there price. So thats the reason why you must use SelectOrder before.

Do 'F1' on OrderOpenPrice to have more info and also look for "Predefined variables"

I'm having trouble reading this. You're saying you want the buylimit entry to be a percentage of the entry? That doesn't make sense to me. The buylimit entry is the entry, no?

He want to sell at 1.2500 and take profit at 1.24...
Right?I'm sure

ps.: By the way, if you want to buy/sell and place after a sell or buy limit order be carefull. If you do this you will be hedging...

Seems there are two entries: one market entry and a buy limit based on a certain percentage of that entry.

That is correct, sorry I wasn't clear.
I am trying to figure out how to set an EA to enter a trade and at the same time or shortly after, set a buylimit based on the price it originally entered. I hope that clears up the confusion.

Not take profit. If I am going long and the trade is going against me, I want to enter a buylimit to add to my position. I would be hedging with a different pair to lower risk and close all trades and pending orders once I have reached a certain amount of profit.

Ok, so its like i said, if you already put your order...
You OrderSelect(...) the order, then use the OrderOpenPrice() to get the entry price.

If you have multiple order on the same currency :
Ex.: Buy at 1.2500 and 1.2550
you can use the Magic Number(magic parameter from OrderSend) to identify each order and OrderType() to get order type (the buy,sell,buy limit and sell limit,etc...) .

I think I got it now. Thank you very much for your responses!

I'm not a programmer, but if I see an example I can figure it out. Could you give me a complete example of how to use OrderSelect() followed by OrderOpenPrice() based on the scenerio we have been following? I know other variables are needed so assume they have been defined.
Thanks

int total = OrdersTotal();

for(int loop=0;loop < total ; loop++ ){<total;loop++){><total;loop++){></total;loop++){></total;loop++){>

if(!OrderSelect(loop,SELECT_BY_POS)){

Print("Error selecting order : ",GetLastError());
return(0); // if your not able to select stop and find out why!
// Or use 'continue' to go back to 'for' to do the second iteration.

}
// ounce you have your order selected verify that is the one you are looking for

if(OrderSymbol() == Symbol() && OrderType()==OP_BUY ){

// you can replace OrderType() and use OrderMagicNumber() == 12345, you can use Magic number
// if you have multiple order (Since you know what number you put in:ex.: 111x buy, 222x buy limit,
// 333x sell, 444x sell limit)

if(!OrderSend(Symbol(),OP_BUYLIMIT,Lots,OrderOpenPrice(),0,Stoploss,OrderOpenPrice()+8*Point)){

Print("Error opening Buy order : ",GetLastError());
return(0);

}else{

break;//if you found what your looking for, you stop turning arround

}

}

}

}

I did this quickly. did not try it. But you get the essential to start i think...
If they are errors sorry.. its for the concept only...

thank you. I'll let you know if I can get it to work

I got it to work with 1 pair but it won't place the buylimit for the second pair. Any ideas? I have each pair assigned to a variable.

What is the error message? In the terminal window under expert tab...
If you use the
Print("Error opening Buy order : ",GetLastError());
it should output the error message.

If not post your code. I look at it...

There isn't an error message listed. All I did was change this working code:
int totalPO = OrdersTotal();
for(int loop=0;loop < totalPO ; loop++ ){
if(!OrderSelect(loop,SELECT_BY_POS)){
Print("Error selecting order : ",GetLastError());
return(0); // if your not able to select stop and find out why!
// Or use 'continue' to go back to 'for' to do the second iteration.
}
// once you have your order selected verify that is the one you are looking for
if(OrderSymbol() == Symbol1 && OrderMagicNumber()== Magic && POrder1 == 0){
// you can replace OrderType() and use OrderMagicNumber() == 12345, you can use Magic number
// if you have multiple order (Since you know what number you put in:ex.: 111x buy, 222x buy limit,
// 333x sell, 444x sell limit)
OrderSend(Symbol1,OP_BUYLIMIT,0.01,OrderOpenPrice() - 1.0111,0,0,0,comment,Magic);
if (GetLastError()==0) {POrder1=1;}
//if(!OrderSend(Symbol1,OP_BUYLIMIT,0.01,OrderOpenPrice(),0,0,OrderOpenPrice()+8*Point)){
// Print("Error opening Buy order : ",GetLastError()){POrder1=1};
//}
return(0);
}else{
break;//if you found what your looking for, you stop turning arround
}
}


I basically changed all variables with 1's to 2's for the second pair:

int totalPO2 = OrdersTotal();
for(int loopy=0;loopy < totalPO2 ; loopy++ ){
if(!OrderSelect(loopy,SELECT_BY_POS)){
Print("Error selecting order : ",GetLastError());
return(0); // if your not able to select stop and find out why!
// Or use 'continue' to go back to 'for' to do the second iteration.
}

if(OrderSymbol() == Symbol2 && OrderMagicNumber()== Magic && POrder2 ==0){
// you can replace OrderType() and use OrderMagicNumber() == 12345, you can use Magic number
// if you have multiple order (Since you know what number you put in:ex.: 111x buy, 222x buy limit,
// 333x sell, 444x sell limit)
OrderSend(Symbol2,OP_BUYLIMIT,0.01,OrderOpenPrice() - 1.0104,0,0,0,comment,Magic);
if (GetLastError()==0) {POrder2=1;}
//if(!OrderSend(Symbol2,OP_BUYLIMIT,0.01,OrderOpenPrice(),0,0,OrderOpenPrice()+8*Point)){
// Print("Error opening Buy order : ",GetLastError());

return(0);
}else{
break;//if you found what your looking for, you stop turning arround
}
}

I am sure the problem is simple. Thank you.

Here what i do when i have difficulty.

 

1. I put Print("Stepx"); // X to be replace by number
   1. I put this Print in the code to view the step, I whant to know the code get reach. Sometime you think your code get executed but in faq it doesnt
   2. You can place if(Debug) Print("Step1:xxxx"); // Debug is a global variable bool, set to true if you want to debug, you must not leave this to true when your not.(Because if youre in a loop it will take to much ressource for nothing)

2. Or if i were you, ill put the 2 orders together in a seperate EA to see if the order are executed.
   
   
   

    

   1. Hard coded

Ref.:#2
in the start add:

OrderSend("EURUSD",OP_BUYLIMIT,1,Ask+10*Point,0,Bid-20*Point,Ask+20*Point);

OrderSend("USDCHF",OP_SELLLIMIT,1,Bid+10*Point,0,Ask+20*Point,Bid-20*Point);

if they both get executed, then you have 2 possibilities

 

1. Wrong variable values (But i dont think so since you dont receive message)
2. The order does not get executed(Lets says because one 'if' does not meet criteria by exeample: #1 should give you clues to find it)

Buy the way,
You go from 0 to TotalOrder ( I know i write this )
but you should go backward, from TotalOrders-1 to 0
Why?
the day you would delete one order ( if you dont use by ticket number)
you will have problem. if you count from 0 to TotalOrder , when you reach
2 (The one you want to delete) and you delete it, you continue, then 2 thing happen:

 

1. You will get a loop error
2. and/or if you delete a second order you will get error

Why?
Everytime you delete the TotalOrder change, delete #2, the #3 become #2, #4 become #3 and so on,
So you missed and you delete the wrong one, or at the end you try to read, Total -1 but in fact is Total-2 now.
So begining at the end you are sure to not miss anyone.
