Question About the "For Loop"

[unaizams]

Hi,

Question About the "For Loop".

When does one use "for (i=0;i<limit;i++)" and not "for (i=limit;i>0;i--)" or vica versa? In other words, when one has to count from 1 to 10 or the opposite?

Regards.

it doesnt matter whether you are counting from 1 to 10 or 10 to 1 as you will still be iterating through the loop 10 times..

for(i = 0 - initialises 'i' and sets value to 0
i<limit - while i is less than limit, carry on the loop
i++ - add 1 to i after each iteration

so.....

for (i = 0; i < 10 ; i++)
console.write(i)

and

for(i = 10 ; i > 0 ; i--)
console.write(i)

would equate to 0,1,2,3,4,5,6,7,8,9 0r 10,9,8,7,6,5,4,3,2,1

but would still iterate 10 times - does this answer your question, or have i misunderstood?

Thank you for taking the time to answer.

I am talking about when (in MLQ4) it is suitable, allowed or mandatory to use the incremental counter (i++) and therefore count up and when it is suitable, allowed or mandatory to use the decremental counter (i--) and therefore count down.

For example when:

• Counting open trades
• Modifying open trades
• Closing open trades
• Deleting pending trades

It appears to me that they are not exchangable in every situation so what is the rule for selecting the right ascending or decending counter?

Best regards,
