Plotting

This page explains how to plot prices, indicator, profits.

Table of Contents

Plot price and indicators

Usage for the price plotter: script/plot_dataframe.py [-h] [-p pair]

Example

python script/plot_dataframe.py -p BTC_ETH,BTC_LTC

The -p pair argument, can be used to specify what pair you would like to plot.

Advanced use

To plot the current live price use the --live flag:

python scripts/plot_dataframe.py -p BTC_ETH --live

To plot a timerange (to zoom in):

python scripts/plot_dataframe.py -p BTC_ETH --timerange=100-200

Timerange doesn't work with live data.

Plot profit

The profit plotter show a picture with three plots:

  1. Average closing price for all pairs
  2. The summarized profit made by backtesting. Note that this is not the real-world profit, but more of an estimate.
  3. Each pair individually profit

The first graph is good to get a grip of how the overall market progresses.

The second graph will show how you algorithm works or doesnt. Perhaps you want an algorithm that steadily makes small profits, or one that acts less seldom, but makes big swings.

The third graph can be useful to spot outliers, events in pairs that makes profit spikes.

Usage for the profit plotter: script/plot_profit.py [-h] [-p pair] [--datadir directory] [--ticker_interval num]

The -p pair argument, can be used to plot a single pair

Example

python python scripts/plot_profit.py --datadir ../freqtrade/freqtrade/tests/testdata-20171221/ -p BTC_LTC

When it goes wrong

*** Linux: Can't display**

If you are inside an python environment, you might want to set the DISPLAY variable as so: $ DISPLAY=:0 python scripts/plot_dataframe.py
