Indicator code, please

Hi
I wonder if anyone can help me making a new indicator.
I know it exists in some other platforms but i didn't find it on MT4 and i don't have a clue of how to write an indicator.
so, this indicator should show the firsr bar that its high is higher then the highs of the "n" bars preceding that bar, and the first bar that its low is lower then the lows of the "n" bars preceding that bar.
If the "n" in the input is a problem then 3 will be fine.
This should work on any timeframe.
Hope my description is understandable http://www.forexfactory.com/images/icons/icon9.gif
Thanks.

Did I ask for something that should not be asked?
Is there another reason why I get NO replys?

MrTrader,

You're perfectly entitled to ask for anything you wish.

Whether anybody chooses to down tools, and make the time and effort to research a reply, is their choice. For many of us here, time is money. No offense, but perhaps some people were deterred by the "you owe me a freebee" tone in your post.

The attached indicator plots the highest high for the previous N bars, and the lowest low. Is it close to what you're looking for?

Have you tried the search facilities (e.g. "highest high") on this forum, www.forex-tsd.com and www.mql4.com? Sometimes you can find an answer more quickly this way, rather than waiting for a reply here.

hanover,
thanks a lot for your reply and the time.
I searched the net and found some indicators, none of them were exactly what i kooked for.
the one you were so kind to attach in the closest one.
I was thinking of an arrow drawn above or below the bar each time it reversed.
thanks again.
