ibar shift

New comment
 

Hi...I was hoping someone would know the answer to what I thought would be obvious  ;-)

When I run in an Ea, Test 1 only,   Hrcnttot   increases according to my sendemail details received.  But if I run only test 2 or 3 , Hrcnttot  never changes....  I assume I have misunderstood the ilow shift ... thanks in advance....

 // ############ TEST 1 ###########
  if( iLow(NULL,PERIOD_H1,0)
    > 0.00001 )
     {Hrcnttot=Hrcnttot+1;}

 // ############ TEST 2 ###########
  if( iLow(NULL,PERIOD_H1,-2)
    > 0.00001 )
     {Hrcnttot=Hrcnttot+1;}

 // ############ TEST  3###########
  if( iLow(NULL,PERIOD_H1,-3)
    > 0.00001 )
     {Hrcnttot=Hrcnttot+1;}

  1. Don't paste code
    Play video    		Please edit your post.
    For large amounts of code, attach it.
  2. Post all the relevant code. What is Hrcnttot? Is it initialized? Is it a static or globally declared?
  3. Bar numbers (all shifts) start at zero (currently forming bar) and increase going back in time. What are you passing?
 

Hi WH..

 double Hrcnttot;  // is globally declared as shown here.

I understand all shifts start at zero, and test 1 works fine. it increments  Hrcnttot every tick so the total becomes into the thousands eventually. Tests 1,2&3 are purely tests because I realised shifts -1 -2 -3 etc etc being hourly bars back in time from the current bar zero, were not incrementing.  Hrcnttot represents hour count total in this example and could be used for many purposes..such as counting how many hourly lows in past 3hours or whatever were in a specific price range(determined by other parts of an Ea) I wouldn't be incrementing their...I increment only for this test to try to prove shift -1,-2 etc don't seem to work.

The problem is shift 0 increments but all minus shifts such as -1,-2,-3 etc don't increment.....I hope that's a bit clearer.

Thanks in advance...

 What part of "start at zero and increasing going back in time" was unclear?
 

Hi WH ... to put it another way...if you run this in experts ...test 0 sends an email...but test -1...never does. The only difference I can see is the -1   ....thanks in advance....

-1 is decreasing from zero - BOGUS

Asked and answered three times.

 
anyway ...after all the bogus .... I obviously missed the obvious...I changed -1 to +1 etc and it worked ;-))   ....bottle of whisky to you WH for your persistence ;-))
