A Python script for monitoring products supported by coinbase in real time
The script is written in Python and subscribes to the websocket feed provided by coinbase. It leverages the APIs provided by an unofficial Python client for coinbase. Users can select products they want to monitor and view live changes in their prices.
The script is tested with Python v3.8.2. It has the following dependencies:
The dependencies can be installed with the help of the requirements.txt file included in this repository.
> pip3 install -r requirements.txt
usage: monitor.py [-h] [-f PLOTS_PER_FIG] [-i ANIMATION_INTERVAL] [-m MAXLEN] [-p PRODUCTS] [-s] [-c SELECT_CURRENCY] [-q]
Monitor prices of cryptocurrencies
optional arguments:
-h, --help show this help message and exit
-f PLOTS_PER_FIG, --plots-per-fig PLOTS_PER_FIG
maximum number of plots per figure (default: 2)
-i ANIMATION_INTERVAL, --animation-interval ANIMATION_INTERVAL
interval (in milliseconds) after which animation is updated (default: 1000)
Warning: low interval might increase resource usage
-m MAXLEN, --maxlen MAXLEN
maxium number of data points to show on plots (default: 1000)
Warning: high number of data points might increase resource usage
-p PRODUCTS, --products PRODUCTS
comma separated list of products to monitor (e.g., -p BTC-USD,ETH-USD,XLM-USD) (default: BTC-USD)
-s, --show-supported-products
display products supported by coinbase (default: show all products; filter using --select-currency)
-c SELECT_CURRENCY, --select-currency SELECT_CURRENCY
display products supported by coinbase in a specific quote currency (default: show all products; similar to --show-supported-products)
-q, --show-supported-quote-currencies
display supported quote currencies
By default, BTC-USD is monitored if no arguments are provided.
> python monitor.py
Additional products can be monitored via the -p switch.
> python monitor.py -p BTC-USD,ETH-USD
In fact, several products can be monitored at once.
python monitor.py -p BTC-USD,ETH-USD,BCH-USD,XLM-USD
By default, the script shows two plots per figure. However, this can be modified using the -f switch. In addition, the rate at which the plots are updated can be changed from the default of once every 1000 milliseconds to a user-defined value using the -i switch. Each plot retains 1000 data points by default. Once more than 1000 data points have been received, older data points are truncated. This value can be modified by providing a new value by using the -m switch.
> python monitor.py -p BTC-USD,ETH-USD,BCH-USD,XLM-USD -f 4 -i 100 -m 25
Products supported by coinbase can be viewed with the help of the -s, -c, or -q switches. See usage for details.
