In lazytrade: Learn Computer and Data Science using Algorithmic Trading

Description

PURPOSE: Function that uses Deep Learning model and Time Series Column of the dataframe to find out specific market type of the financial asset it will also discard bad result outputting -1 if it is the case

Usage

mt_stat_evaluate(x, path_model, num_bars, timeframe)

Arguments

x	dataframe with one column containing asset indicator in the time descending order, typically 64 or more values
path_model	String, path to the model
num_bars	Integer, Number of bars used to perform transformation
timeframe	Integer, timeframe in Minutes.

Value

dataframe with predicted value of the market type
