What Is The Aroon Indicator & How ... - Honest Forex Reviews

Is this a good use case for a macro?

I'll preface this with I have done OOP all my professional and amateur career (save for the one semester of BASIC I took in high school) and I'm still having issues understanding macros and the best way to use them.
That said, I'm writing a library to use for technical analysis on stocks/forex/futures/etc and am getting to the Aroon indicator. Basically the calculation is the same except for looking for a high for one part and then the low for the other part. Below is my naive first pass at solving the problem:
def aroon_up(prices) do number_of_periods = prices |> Enum.count corrected_prices = prices |> Enum.reverse high_period = calc_high(prices, 0, 0) (number_of_periods - high_period) / (number_of_periods * 100) end defp calc_high(prices, high, count) do case prices do [hd | tl] when hd > high -> calc_high(tl, hd, count + 1) [hd | tl] -> calc_high(tl, high, count + 1) [hd] when hd > high -> count _ -> count end end def aroon_down(prices) do number_of_periods = prices |> Enum.count corrected_prices = prices |> Enum.reverse low_period = calc_low(prices, nil, 0) (number_of_periods - low_period) / (number_of_periods * 100) end defp calc_low(prices, low, count) do case prices do [hd | tl] when low == nil -> calc_low(tl, hd, count + 1) [hd | tl] when hd < low -> calc_low(tl, hd, count + 1) [hd | tl] -> calc_low(tl, low, count + 1) [hd] when low == nil -> count [hd] when hd < low -> count _ -> count end end 
You'll notice there is a lot of repeating code. I'd love to be able to generate the base of the code from a macro but I'm stumped on how to do this without basically writing a bunch of case statements. Is this a valid use case for macros here or am I just over thinking the problem?
