Bollinger Bands - I'm willing to write indicators!

Has anyone seen this site? http://www.bbforex.com/lists/
I ask because I want to code what they do. But I can't find on the 'net what the formulas are let alone what the trigger levels are for each.

If anyone can point it out to me, please do. I'll program the indicators!

I like the charts on the bbforex and use the trend line drawing option and the lists too. The entire website including the lists are totally free so why bother to recode it?

I read his book Bollinger on Bollinger Bands and he explains similar trading systems there but using the equities markets not forex. That might provide insight into the trigger levels if you want to pursue it.

Thanks.

I want to put the indicators on Metatrader4. This way I can mess w/ the settings and code a little to suit me.
