It is a great indicator but When it works!!!
If you have one or two charts it might work for a while otherwise under medium loads of multiple charts with other indicators It wont handle the load and will not respond any clicks or freeze it self and candle bars stops updating real-time completely .Also I am getting error messages like" indicator too slow rewrite the code etc." or "array out of range" I ve contacted with author and followed his recommendations but did not make any difference at all!!!! Author still insists not to update/correct the indicator,he says it works flawlessly...
This indicator with other products of FerruFx, makes a great trading system ! . I am very satisfied :)
