(Req) DecisionBar mt4


Recommended Posts

Re: REQ DecisionBar mt4

 

After having both side by side I can say that there is not much difference between the DecisionBar indicators and FractalChannel. As a matter of fact DecisonBar's indicators are harder to use I think. But they both give identical signals, which means that DecisionBar is based on Bill William's fractals

 

here is fractal
