cr1- allows you to set alerts based on if DI+ and DI- crossover each other leading to a new trend
cr2- shows a constant background highlight of a trend.
threshold- you can set a threshold value so that any readings below that are ignored and the indicator paints a blank black area instead.
cr3 and cr4 are experimental- would not reccommend using yet (they were part of a test I did)
