help with making a loop command for swing indicator

Hello... Thanks in advance

I'm only at a basic level when it comes to creating indicators.

I've been working on a new one that uses the Swing indicator in it.

Works great until I found that the Swing indicator can have consecutive highs or consecutive lows..

When that occurs I require to use the highest of the consecutive highs and low for lows.

I think I need to use a "loop" to achieve this but never used one before.

Where can I learn how to do this, or if somebody could help get past this that would be great..

Thanks.
