LocalBitcoins

LocalBitcoins data is available via its API. For example, the following URL gives data on current trades in GBP available by national bank transfer:

• https://localbitcoins.com/buy-bitcoins-online/GB/united-kingdom/national-bank-transfer/.json

The data returned by the API is of a form like this.

The function values_Bitcoin_LocalBitcoin returns the price values returned by calling the API in this way.

import denarius
denarius.values_Bitcoin_LocalBitcoin()

The script loop_save_LocalBitcoins_values_to_database.py loop records LocalBitcoins data to database. To address closed gateways arising from repeat calls, the script could be used in a way like the following:

while true; do
    loop_save_LocalBitcoins_values_to_database.py --timeperiod=3600
    sleep 5400
done

databases

A database of Bitcoin values can be saved in the following ways:

import denarius
denarius.save_database_Bitcoin(filename = "database.db")

import denarius
denarius.save_database_Bitcoin(filename = "database_Bitcoin_EUR.db", currency = "EUR")
denarius.save_database_Bitcoin(filename = "database_Bitcoin_GBP.db", currency = "GBP")

graphs

The function save_graph_Bitcoin creates a graph of Bitcoin historical values over a specified time. The function save_graph_LocalBitcoins creates a graph of LocalBitcoins Bitcoin lowest prices in GBP as recorded in a database by the script loop_save_LocalBitcoins_values_to_database.py.

denarius_graph_Bitcoin

The script denarius_graph_Bitcoin.py displays a PyQt GUI with a graph of the last Bitcoin values.

A graph can be generated of Bitcoin GBP value versus LocalBitcoins GBP lowest 5 values:

import denarius
denarius.save_graphs_Bitcoin_LocalBitcoins()

A graph can be generated of LocalBitcoins normalized prices over days:

A graph can be generated of LocalBitcoins normalized prices over weeks:

A graph can be generated of LocalBitcoins non-normalized prices over weeks:

KanoPool

KanoPool records for addresses can be recorded to CSV in a way like the following:

denarius_loop_save_KanoPool.py --help

denarius_loop_save_KanoPool.py --addresses=1Miner7R28PKcTRbEDwQt4ykMinunhTehs --interval=10

The CSV data can be analysed using the Jupyter Notebook KanoPool.ipynb.

Slush Pool

Slush Pool records for an address can be recorded to CSV in a way like the following:

denarius_loop_save_SlushPool.py --help

denarius_loop_save_SlushPool.py --addresses=1Miner7R28PKcTRbEDwQt4ykMinunhTehs --interval=60 --alarm=11800000 --slushloginname=user --slushworkername=worker1

The CSV fields are, in order, as follows:

• address

• hash rate

• shares

• UNIX timestamp

• unconfirmed reward in Bitcoin

• confirmed reward in Bitcoin

• total reward (confirmed + unconfirmed) in Bitcoin

• total payout since script launch in Bitcoin

• number of blocks found since script launch
