2 Histograms

[wdgigi]

Here is what i need.


I think that the 2nd histogram is : first histogram (osc) minus 5 simple MA of the value of the first histogram.

But i don't know how make this efs, likely as line and not as a histogram.

Will youl help me please?

vHist2 = ((vMA2 - vMA1) - (MAStudy(5, 0, (vMA2 - vMA1), MAStudy.SIMPLE)));


return new Array(vHist1, vHist2);
}


help me!
