System built-in iGator() function is wrong !!!

Yu Zhang 2021.08.10 06:18

look at the code, please note that the parameters is "13,9,9,6,5,3".

//--- paramters is not "13,8,8,5,5,3", is "13,9,9,6,5,3".
   int handle = iGator(_Symbol, _Period, 13,9,9,6,5,3,MODE_SMMA,PRICE_MEDIAN);
   double gator[];
   ArraySetAsSeries(gator,true);
   CopyBuffer(handle, 0, 0, 10, gator);
   Print("System built-in gator:");
   ArrayPrint(gator);
   
   int handle1 = iCustom(_Symbol, _Period, "Examples\\Gator", 13,9,9,6,5,3,MODE_SMMA,PRICE_MEDIAN);
   double gator1[];
   ArraySetAsSeries(gator1,true);
   CopyBuffer(handle1, 0, 0, 10, gator1);
   Print("examples gator:");
   ArrayPrint(gator1);
   
   int handle2 = iCustom(_Symbol, _Period, "Examples\\Gator_2", 13,9,9,6,5,3,MODE_SMMA,PRICE_MEDIAN);
   double gator2[];
   ArraySetAsSeries(gator2,true);
   CopyBuffer(handle2, 0, 0, 10, gator2);
   Print("examples gator_2:");
   ArrayPrint(gator2);

Use it on EURUSD and the result is :

2021.08.10 14:11:24.442 test (EURUSD,D1)        System built-in gator:
2021.08.10 14:11:24.442 test (EURUSD,D1)        0.00098 0.00125 0.00209 0.00308 0.00413 0.00477 0.00519 0.00557 0.00572 0.00601

We can see the result of iGator() is shifted. And if we try to add system built-in gator indicator to EURUSD Chart. And see Data Window, the result is:

It also tell us system built-in iGator() function is wrong !!!

You compare the parameters you use 13,9,9 with 13,9,5. Who is wrong?
