Algorithmic-trading Library in Python

The AT Library is a python library that can be used to create trading algorithms using technical indicators. It's built on Pandas, Numpy, and Matplotlib.

How to use (Python 3)

First download the code of the library.it can be found in AT (or download the new version AT) and put it in your working directory or use

import os
path="C:/Users/pc/Desktop/..."  # the location of the downloaded code 
os.chdir(path)

Then import the libray :

import AT as at

Genetic Algorithms

A genetic algorithm (GA) is a metaheuristic inspired by the process of natural selection that belongs to the larger class of evolutionary algorithms (EA). Genetic algorithms are commonly used to generate high-quality solutions to optimization and search problems by relying on biologically inspired operators such as mutation, crossover and selection.(Mitchell, Melanie (1996). An Introduction to Genetic Algorithms)

In this project, we used the DEAP library to implement genetic algorithm. In our case, we used those technics:

            * Selection: Tournament selection (tools.selTournament)
            * Crossover: Simulated Binary Crossover (tools.cxSimulatedBinaryBounded)
            * Mutation: polynomial mutation (tools.mutPolynomialBounded )

Updates

Instead of creating just one module that contains all functions, we create a package AT_new_version that contain 5 modules. Each one has a specific task.

There are 5 modules in the package:

           * Indicators: to compute technical indicators
           * Signal: To generate trading signals 
           * GraphIndicators: To visualize technical indicators
           * GraphSignal: To visualize trading signals
           * Performance: Tools to evaluate trading strategies
