A Python library which provides several algorithms to detect arbitrage opportunities across over 90 cryptocurrency exchanges in 34 countries
- Ensure you have installed pip.
- Run the following in your command line:
pip install git+git://github.com/Stakedllc/peregrine.git
This section provides a brief overview of Peregrine's functionality. Examples demonstrating many more features are available in peregrine/examples.
from peregrinearb import get_opportunity_for_market
import asyncio
opportunity = asyncio.get_event_loop().run_until_complete(get_opportunity_for_market("BTC/USD"))
print(opportunity)At the time of writing, this prints the following in less than one second.
{'highest_bid': {'exchange': <ccxt.async.lakebtc.lakebtc object at 0x10ea50518>, 'price': 11750.59},
'lowest_ask': {'exchange': <ccxt.async.gdax.gdax object at 0x10ea50400>, 'price': 8450.01}}
If you want to specify which exchanges to find opportunities on:
from peregrinearb import get_opportunity_for_market
import asyncio
opportunity = asyncio.get_event_loop().run_until_complete(get_opportunity_for_market("BTC/USD", exchange_list=["anxpro", "bitbay", "coinfloor", "gemini", "livecoin"]))
print(opportunity)If you want to find opportunities on the exchanges of only a certain country1, you can do it like so:
from peregrinearb import build_specific_collections, get_opportunity_for_market
us_eth_btc_exchanges = build_specific_collections('countries'=['US'])
opportunity = get_opportunity_for_market("ETH/BTC", us_eth_btc_exchanges["ETH/BTC"])
print(opportunity)1Accepted arguments in place of "US" in this example are Austria, Australia, Bulgaria, Brazil, British Virgin Islands, Canada, China, Czech Republic, EU, Germany, Hong Kong, Iceland, India, Indonesia, Israel, Japan, Mexico, New Zealand, Panama, Philippines, Poland, Russia, Seychelles, Singapore, South Korea, St. Vincent & Grenadines, Sweden, Tanzania, Thailand, Turkey, UK, Ukraine, and Vietnam.
import asyncio
from peregrinearb import load_exchange_graph, print_profit_opportunity_for_path, bellman_ford
graph = asyncio.get_event_loop().run_until_complete(load_exchange_graph('binance'))
paths = bellman_ford(graph, 'BTC')
for path in paths:
print_profit_opportunity_for_path(graph, path)This prints all of the arbitrage opportunities on the given exchange (in this case, Binance). At the time of writing, the first opportunity printed out is:
Starting with 100 in BTC
BTC to USDT at 7955.100000 = 795510.000000
USDT to NEO at 0.016173 = 12866.084425
NEO to ETH at 0.110995 = 1428.071041
ETH to XLM at 2709.292875 = 3869062.695088
XLM to BTC at 0.000026 = 100.208724
If you would like to account for transaction fees, set fees=True when calling load_exchange_graph.
import asyncio
from peregrinearb import load_exchange_graph, print_profit_opportunity_for_path, bellman_ford
loop = asyncio.get_event_loop()
graph = loop.run_until_complete(load_exchange_graph('binance', fees=True))
paths = bellman_ford(graph, 'BTC', unique_paths=True)
for path in paths:
print_profit_opportunity_for_path(graph, path)from peregrinearb import create_weighted_multi_exchange_digraph, bellman_ford_multi, print_profit_opportunity_for_path_multi
graph = create_weighted_multi_exchange_digraph(['kraken', 'bittrex', 'gemini'], log=True)
graph, paths = bellman_ford_multi(graph, 'ETH')
for path in paths:
print_profit_opportunity_for_path_multi(graph, path)This prints all of the arbitrage opportunities on the given exchanges. At the time of writing, the first opportunity printed out is:
Starting with 100 in ETH
ETH to ANT at 204.26088199848851 = 20426.08819984885 on bittrex for ANT/ETH

USD to ETH at 0.0017965900720432618 = 104.21100149317708 on kraken for ETH/USD
Should you like to account for transaction fees. In the example above, simply set fees to True when calling create_weighted_multi_exchange_digraph.
For example, the following code prints out all of the opportunities found on the given exchanges while accounting for fees:
from peregrinearb import create_weighted_multi_exchange_digraph, bellman_ford_multi, print_profit_opportunity_for_path_multi
graph = create_weighted_multi_exchange_digraph(['exmo', 'binance', 'bitmex', 'bittrex', 'gemini', 'kraken'], log=True)
graph, paths = bellman_ford_multi(graph, 'ETH', unique_paths=True)
for path in paths:
# total = calculate_profit_ratio_for_path(graph, path)
# print(path)
print_profit_opportunity_for_path_multi(graph, path)The most profitable of the two printed out is:

- Implement a fix to convert from USDT to USD and back again for markets based on USDT
- Write better/ more examples and unit tests
- Create (better) data visualizations (The Networkx documentation provides some useful guides on drawing Networkx graphs)
- Implement machine learning to see which markets or exchanges consistently host the greatest disparities
- Update cythonperegrine to reflect some of the changes to peregrine
- Update doc strings to the same standard as NumPy and SciPy
- Related to the above, implement feature to find maximally profitable arbitrage opportunity.
