To compute the Stochastic Oscillator in Erlang, you can use the following steps:
Here's a simple Erlang function that demonstrates how to compute the Stochastic Oscillator:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
-define(PERIOD, 14). -define(SMA_PERIOD, 3). stochastic_oscillator(Prices) -> High = lists:sublist(Prices, ?PERIOD), Low = lists:sublist(Prices, ?PERIOD), {HighPrice, _} = lists:max(High), {LowPrice, _} = lists:min(Low), CurrentPrice = lists:last(Prices), K = ((CurrentPrice - LowPrice) / (HighPrice - LowPrice)) * 100, D = calculate_sma([K | lists:sublist(Prices, ?SMA_PERIOD)], ?SMA_PERIOD), {K, D}. calculate_sma(Values, Period) -> {Sum, _} = lists:foldl(fun(X, {Acc, Count}) -> {X + Acc, Count + 1} end, {0, 0}, Values), Sum / Period. |
You can call the stochastic_oscillator
function with a list of price values for a specific asset to calculate the %K and %D values. Remember to adjust the PERIOD
and SMA_PERIOD
constants as needed.
