Count cross

How to count price crosses any line?

Take a look at crossUnder and crossOver functions

If you want to count them in the past you will also want Bar() too

thank you for your advise

i think bar() function can't count that price crosses any line.

You're absolutely right. It counts bars. So use the value of Bar() to loop over bars in the past and count each time an event occurs.

Unless there is a special function for such a thing that's how I would do it.

EDIT: C, like many languages is case sensitive. Bar() != bar()

is it possible to chat with you through any social chat app?

I'm not on any social netwonking sites. But if you post some code I'd be glad to try and help further.

How to write code that price crosses first time upper bollinger band line. Actually there many crosses upper bollinger band line. I need the first cross.

It needs to be relative to some other event otherwise you will just get the first cross in the simulation period.

Can you write code about it? I think it is easy for you.
