The program is Amibroker Scilliams.
A fellow Amibroker user sent the swing chart code to me - nice isn't it?

The ribbons are mine :)
Good luck with your currency learning - is on my to do list too. I remember from a long time ago that a 25 point swing on the Swiss Frank worked like a charm - captured all the moves for a long time - don't know it it still does.
And I wonder whether point swings would be worth testing on other currencies - for those clever enough - but could be done with the eye I guess.
