"merge" function messes up MACD values

[iuliancioarca]

I was wondering why the macd function does not return the same values as a manually computed one so I started debugging. So far so good up until (just the classical MACD implementation):

MarketTechnicals.jl/src/momentum.jl

Line 113 in f0b6e22

sig = ema(dif, signal, wilder=wilder)

Ahead to

MarketTechnicals.jl/src/momentum.jl

Line 119 in f0b6e22

merge(merge(osc, dif), sig, colnames=new_cols)

and the return results are different from the dif/sig/osc values.
