I use different ZUP's. The last ones are the best. The last one on this forum is ZUP_v73. There is ZUP_v74 but is not spread out by Nen. If you want to learn about harmonic numbers read books by Larry Pesavento. ZUP's has function to show not only harmonic numbers but even more. There are instructions for ZUP's. Forgive me, but I will not give to people everything. Trading is an ART. ART brings money. It works only this way. I wish all people the best in trading.
