Python code for creating candlestick charts with slider using Bokeh

Creating candlestick charts with range slider using bokeh

This code snippet simulates parts of the workflow used in technical analysis:

• connecting to a sql database to extract price data for a specific trading instrument, and
• plotting a candlestick chart with a range slider and a tooltip for detailed price info

For illustration, I'm using daily OHLC price data for two instruments (EURUSD currency pair, and Apple stock) stored in a sqlite database, where each instrument represents a table. The script can easily be adopted to plot from csv files, assuming they contain the columns date, open, high, low & close.

Usage:

Required dependencies:

• bokeh
• pandas

To use with pipenv, run:

• pip install pipenv to install pipenv
• pipenv install to install dependencies
• bokeh serve --show plotting.py to open in browser
