[amibroker] Looping - our previous discussion

[bernardedmond01]

Ed
You assisted me with the following code (your code) on March 23rd. 
The background to our discussion was that I wanted to understand how 
to hold for a number of periods.
I wondered if I could ask you a couple of questions on your code (at 
end):

SetBarsRequired(10000,10000); 

triggerPercentage = 1.03; 
waitPeriod = 15; 

Setup = C < BBandBot(C,20,2); 

for (i = 0; i < BarCount - waitPeriod; i++) { 

   if (Setup[ i ]) { 

      for (j = i + 1; j < i + waitPeriod; j++) { 
       
         Setup[ j ] = 0; 
       
      } 

      i = j; 

   } 

} 

 
1. Is it correct to refer to the j loop as being "nested" in the i 
loop? I'm wondering whether the j loop completes its internal loop 
for the 15 or so bars and then re-enters the i loop at the end or 
whether both i and j loops run the 15 or so times?

2. "i<BarCount-waitperiod" – can you explain how the code translates 
that please? I thought that would have  meant you terminate once the 
current bar is less than the total number of bars less 15, whereas 
it seems to me an you terminate at 15.

3. You mentioned when we previously discussed this issue that Setup 
has a "1" wherever C < BBandBot. Is that why in other codes, 
sometimes the values of an array are set to 0 before a loop (to 
remove any previous arrays triggered)?

Thanks for your assistance,
Bernard
