Hi, new to the forums, new to ProRealTime programming. First off, having some C coding experience the concept of the code iterating through each bar automatically is a concept I need to get used too. In C/C++ you would need to code that element too.

I am working through Advanced programming > Loops > Descending loops and got to the code

ema20=average[20,1]
ema50=average[50,1]
result=0

FOR x = 100 DOWNTO 0 DO
result = result+(ema20[x]>ema50[x])

IF result = 50 THEN
 BREAK
ENDIF

IF result < 30 THEN
 CONTINUE
 ENDIF

IF result = 30 then
 signal = 30
ELSE
 signal = 0
ENDIF

NEXT

return result, (ema20>ema50), signal

My question (probably the first of many) is that as noted in the ‘IF result = 30 THEN signal = 30’ test, once ‘signal’ is equal to 30 it gets set at 30. However the true value of ‘signal’ is 30 or below and does not get reset to 30 again until ‘signal’ moves above 30. Isn’t his poor programming? Shouldn’t ‘signal’ get reset to zero just after the last ENDIF and before NEXT. I realise that this is just a teaching exercise but want to make sure I understand this correctly. Or is it simply dependant on exactly what you are trying to achieve? Thank you for your time.
