Question Edit indi zigzag sup-res

MazquFx · 05 Oct 2015

apakah ada rekan-rekan yang bisa membantu untuk merubah logic inikator zigzag ini, soalnya saya masih bingung,
indikator ini akan membuat dot setelah terbentuk support dan resisten nya
versi aslinya , jika terbentuk support bawah maka akan ada dot di bawah[low]
, jika terbentuk resisisten atas maka akan ada dot di atas[high]

versi yang saya akan rubah:
jika , terbentuk support bawah, maka indi akan membentuk dot di [high] candle tersebut
dan jika terbentuk resisten atas, maka indi akan membentuk dot di [low] candle tersebut.

secara penampakan, http://prntscr.com/8nw82l

keterangan, dot adalah versi indi aslinya,
garis gold adalh dot yang saya inginkan biar keluar di high//low nya
