I can't get ideea where I'm wrong - Fibonacci tool follower

[Mesterica]

Hi, could someone give a hand of help?

I;m trying code a EA for MT4 .

The EA checks if the Fibonacci Retracements tool exists on the open chart of the trading instrument. If it exists, the EA reads the price value corresponding to Level 0 and the price value corresponding to Level 1 in the Fibo. It stores these values. The value of Level 1 is permanent and does not change.

If the price value corresponding to Level 0 increases, then automatically adjusts the fibo tool accordingly with the price.

If the value of Level 0 decreases, it holds the fibo tool at the highest price recorded before the fall, in which case the fibo ratios will not change.

I use the code:

#property copyright "Mesterica"

#property version   "1.00"


double Level0 = 0;
double Level1 = 0;
double highestPrice = 0;


int OnInit()
{
    // Check if the Fibonacci Retracements tool exists on the chart
    if (ObjectFind("Fibo") < 0)
    {
        Print("Fibonacci Retracements tool not found on chart.");
        return INIT_FAILED;
    }
    return INIT_SUCCEEDED;
}


void OnTick()
{
    // Get the price values corresponding to Level 0 and Level 1 in the Fibo
    Level0 = ObjectGetValueByShift("Fibo", 0, OBJPROP_PRICE1);
    Level1 = ObjectGetValueByShift("Fibo", 0, OBJPROP_PRICE2);


    // Store the highest price if Level 0 decreases
    if (Level0 < highestPrice)
    {
        highestPrice = Level0;
    }
    else if (Level0 > highestPrice)
    {
        // Update the fibo tool if the price value corresponding to Level 0 increases
        ObjectMove("Fibo", 0, TimeCurrent(), highestPrice, Level1);
    }
}

But after compiling I receive these errors: https://prnt.sc/oT4ikDLzzYbE

edit your post and use the code button to insert your code properly  </> or Alt-S  

don't use links to the errors put them in your post or attach them

Hello . 

You don't need to use GetValueByShift for fibonacci as the lines are horizontal and dont change 

Here is an example that reads all the fibo lines on the chart , their price and their ratio .

Specific to your issue , to get the prices use these :

  double onePrice=ObjectGetDouble(ChartID(),sparam,OBJPROP_PRICE,0);//get   100% retracement price
  double zeroPrice=ObjectGetDouble(ChartID(),sparam,OBJPROP_PRICE,1);//get 0% retracement price

Then the fibo offers the ratio of each level which can help you project the price of any level the user has active 

int total_levels=(int)ObjectGetInteger(ChartID(),sparam,OBJPROP_LEVELS);
  double onePrice=ObjectGetDouble(ChartID(),sparam,OBJPROP_PRICE,0);//get   100% retracement price
  double zeroPrice=ObjectGetDouble(ChartID(),sparam,OBJPROP_PRICE,1);//get 0% retracement price
  double range=onePrice-zeroPrice;
  for(int i=0;i<total_levels;i++)
     {
     double value=ObjectGetDouble(ChartID(),sparam,OBJPROP_LEVELVALUE,i);//ratio
     double price=zeroPrice+range*value;
     }

The example in full code for testing :

  int total_levels=(int)ObjectGetInteger(ChartID(),sparam,OBJPROP_LEVELS);
  Print("Fibo spotted , "+IntegerToString(total_levels)+" levels");
  double onePrice=ObjectGetDouble(ChartID(),sparam,OBJPROP_PRICE,0);//get   100% retracement price
  double zeroPrice=ObjectGetDouble(ChartID(),sparam,OBJPROP_PRICE,1);//get 0% retracement price
  double range=onePrice-zeroPrice;
