how to get the "peak" K line and "valley" K line in a charting formed by many K lines.
vx0532:
What is a "K line" ?
I mean whether there is a function in MQL4 to do this?
if there is, shall I know which function?

This is a "charting formed by many K lines".
This is a "K line".

OK, so a candle or a bar . . . use iHighest() and iLowest() <--- click for the documentation.
