How can I set buy limit and sell limit on fibonacci levels?

[Ali Azizifar]

Hi, I codding a custom fibo levels but when i set orders i do not take an answer.

The code is here:

   if( Fibonacci() == 0.78)
     {
      OrderSend(Symbol(), OP_BUYLIMIT, lot, Bid, 3, StopLoss, TakeProfit, NULL, 0, 0, Green);
     }

   if( Fibonacci() == 0.618)
     {
      OrderSend(Symbol(), OP_SELLLIMIT, lot, Ask, 3, StopLoss, TakeProfit, NULL, 0, 0, Red);
     }

I already define lot,...

Can anyone help ME?

It appears your Fibonacci() function detects when price is on those levels .
If yes ,then send OP_BUY on the first case ,and OP_SELL on the second case.(instant trade)

If not , then send the price at the fibonacci level instead of the Bid or Ask prices.(pending trade)

   You can't create pending orders at market prices.

   Check your return codes, and report your errors. Don't look at GLE/LE unless you have an error. Don't just silence the compiler, it is trying to help you.

Thank you.

The error is -->  Fibonacci: failed to create => Fibo object! Error code = 4200 and I don't know what is that for.

I am new member & I don't know about that section.

I change the Bid & Ask, But the error is -->  Fibonacci: failed to create => Fibo object! Error code = 4200 and I don't know what is that for.

I understand that you have a function which scans the Fibonacci Retracement object that was placed on the chart manually ? 

try measuring with this if you know the fibonacci swing points

double WhereIsPriceInFibonacciRetracement(double past_swing_point,
                                          double recent_swing_point,
                                          double current_price)
{
double fib_where=0;
double unit=MathAbs(past_swing_point-recent_swing_point)/100;
if(unit>0)
{
fib_where=100-((current_price-past_swing_point)/unit);
}
return(fib_where);
}

Your tip help me but I still have problem.

The error is -->  Fibonacci: failed to create => Fibo object! Error code = 4200 and I don't know what is that for.
