I made an Indicator which can draw a line on chart as below; some time this line cross the bars around it and some time this line always run above / below bars as below: the first situation: the second situation: So I want to get a good method of differing these two situations.

I find that the existing MQL4 tutorials and texts and reference material are fine to read through to learn about MQL4 by topic and aspect, but are not at all well structured and laid out when one is writing an MQL4 program and having problems there. i.e. they are not very useful to refer to by...
