Problems with MetaEditor

Hi guys, Could someone tell me, why MetaEditor sometimes ignore this command, what is wrong with it? is it becuase Relational operations or while command or what? because sometimes it shows ext1buffer when k>4... Thank you (my metaeditor version is 5.00 b1241)

Inserted Code
              k=0; p=0;
              while(p<=9){ p++;
              if ((Close[i+p]/Poin==(Open[i+p]/Poin+1)) || (Open[i+p]/Poin==(Close[i+p]/Poin+1))) k++;}
              if (k<=4)
              Ext1Buffer=1

Be careful about the operations precedence. Metaeditor is now strict about this.

Not sure if that's your issue, but by first looking, I can see few precedences to be addressed.

What I was referring to is this : https://docs.mql4.com/basis/operations/rules

You will then see that you might have to add some additional parenthesis to be sure the math is done correctly.

Again, I am not saying that it's your issue ... Just to be sure you understand the precedence rules in your "maths".

you are right man, change
"((Close[i+p]/Poin==(Open[i+p]/Poin+1))" and "(Open[i+p]/Poin==(Close[i+p]/Poin+1))"

to "((Close[i+p]/Poin)==((Open[i+p]/Poin)+1))" and "((Open[i+p]/Poin)==((Close[i+p]/Poin)+1))"

and it solved.. why Metaeditor like parenthesis so much dont understand this language design

Thank you man, really appreciate it..

have that problem again.. i think something wrong with these operations, they cant recognize the numbers
kill 2 days of mine with this idiotic problem...

ok, i changed k<=4 to k<5 and used lots of parenthesis and problem is solved.. there is something wrong with these operations...
