TA-Lib

A Julia wrapper for TA-Lib (Technical Analysis Library)

Sample / Features

TALib.jl supports both Array and DataFrames thanks to multiple dispatch.

julia> using TALib

julia> using DataFrames
julia> filename = "test/ford_2012.csv"
julia> dfOHLCV = readtable(filename)
julia> dfOHLCV[:Date] = Date(dfOHLCV[:Date])

Development

See discussion and roadmap here:

https://github.com/femtotrader/TALib.jl/issues/1
There is 3 levels of functions
- level 0: raw C TA-Lib function calls
- level 1: function with Julia Arrays as inputs / outputs
- level 2: more high level functions with
  - DataFrame (from DataFrames.jl) as inputs / outputs
  - TimeArray (from TimeSeries.jl) as inputs / outputs
