Read the help manual. Especially the one about array processing and
how AmiBroker is an array processing language. Read it multiple
times :) .. took me three times before it clicked. Once it did,
everything was much simpler
1 - Peakbar with the 0 will give you the high without a percentage
Change... I just noticed ther eis also hhvbars.. so you can use that
to get the bar number..but that function gives you "number of
periods that have passed since the closing price reached its 'N'
peak'" where N is the number of periods.. in your case.. 20..
2 - the formula I put down gives you the bar number. if you know the
bar number, then HIGH[bar] gives you the high..
You only loop if you want to go through the array. otherwise all
functions work on the entire array(hint..hint.. High is an array of
highs for the current symbol :) )
