Yep have got that thanks.

I did some more checking on the difference between MM as comes with the Dolly and the one I use. I am not a programmer but I think, if I undestand the code, the Dolly version uses the High High & Low Low of the period to calculate the lines.
The indicator I use works on the Highest close & the lowest close for the period.
So, if that is the case that is where the difference comes from when it calculates. Murrey uses the close to calculate.
As I said I might be wrong on this, hope CJA has time to check it out.

Thanks again
