Does anyone have any documentation on the folmula to build Renko charts ? My traders want to use it on a new strategy gray box but I cannot find any technical documentation on building the chart.
See Achelis, TA from A to Z, pgs 233, 258-9 and 275. 275 shows 3 line breaks which you may want to develop as well for comparison.
Take a look at this companies SDK.. http://www.linnsoft.com/renko/ This is actually a very simple formula/code..nothing to hard to build.
