Thanks Progster - I have just started working with looping and I have
your information provides a important building block.
I know how to identify pivots but my question is how do I reference
the price of the past trough when a new peak is reached or vice versa?
It seems it should be simple but I am struggling with it.
Any help is appreciated.
TIA,
David K.
