Expert advisor Parabolic SAR

[Francesco Martinelli]

Hi all 

i'd like to code an expert advistor in mql5 for the Parabolic SAR indicator that give the same results of the default indicator availble on metatrader 5 menu'.

I coded using this examples https://www.youtube.com/watch?v=UiIOHeewo5k&t=267s.

That version works quite good but when the SAR trend switch the first green dot diverge from the calculated value.

This is the code (called on ontick function)

   double mySARArray[];

   isar =iSAR(trdsymbl,period,0.02,0.2);

   ArraySetAsSeries(mySARArray,true);

   CopyBuffer(isar,0,0,3,mySARArray);

   double psar=NormalizeDouble(mySARArray[1],5);   

   Comment("PSARValue ",psar);

attached on this message the picture where the error is visible
