vectorbt - blazingly fast backtesting and interactive data analysis for quants

I want to share with you a tool that I was continuously developing during the last couple of months.
https://github.com/polakowo/vectorbt

As a data scientist, when I first started flirting with quant trading, I quickly realized that there is a shortage of Python packages that can actually enable me to iterate over a long list of possible strategies and hyper-parameters quickly. Most open-source backtesting libraries are very evolved in terms of functionality, but simply lack speed. Questions like "Which strategy is better: X or Y?" require fast computation and transformation of data. This not only prolongs your lifecycle of designing strategies, but is dangerous after all: limited number of tests is similar to a tunnel vision - it prevents you from seeing the bigger picture and makes you dive into the market blindly.
After trying tweaking pandas, multiprocessing, and even evaluating my strategies on a cluster with Spark, I finally found myself using Numba - a Python library that can compile slow Python code to be run at native machine code speed. And since there were no packages in the Python ecosystem that could even closely match the speed of my own backtests, I made vectorbt.
vectorbt combines pandas, NumPy and Numba sauce to obtain orders-of-magnitude speedup over other libraries. It builds upon the idea that each instance of a trading strategy can be represented in a vectorized form, so multiple strategy instances can be packed into a single multi-dimensional array. In this form, they can processed in a highly efficient manner and compared easily. It also integrates Plotly and ipywidgets to display complex charts and dashboards akin to Tableau right in the Jupyter notebook. You can find basic examples and explanations in the documentation.

Below is an example of doing in total 67,032 tests on three different timeframes of Bitcoin price history to explore how performance of a MACD strategy depends upon various combinations of fast, slow and signal windows:
import vectorbt as vbt import numpy as np import yfinance as yf from itertools import combinations, product # Fetch daily price of Bitcoin price = yf.Ticker("BTC-USD").history(period="max")['Close'] price = price.vbt.split_into_ranges(n=3) # Define hyper-parameter space # 49 fast x 49 slow x 19 signal fast_windows, slow_windows, signal_windows = vbt.indicators.create_param_combs( (product, (combinations, np.arange(2, 51, 1), 2), np.arange(2, 21, 1))) # Run MACD indicator macd_ind = vbt.MACD.from_params( price, fast_window=fast_windows, slow_window=slow_windows, signal_window=signal_windows, hide_params=['macd_ewm', 'signal_ewm'] ) # Long when MACD is above zero AND signal entries = macd_ind.macd_above(0) & macd_ind.macd_above(macd_ind.signal) # Short when MACD is below zero OR signal exits = macd_ind.macd_below(0) | macd_ind.macd_below(macd_ind.signal) # Build portfolio portfolio = vbt.Portfolio.from_signals( price.vbt.tile(len(fast_windows)), entries, exits, fees=0.001, freq='1D') # Draw all window combinations as a 3D volume fig = portfolio.total_return.vbt.volume( x_level='macd_fast_window', y_level='macd_slow_window', z_level='macd_signal_window', slider_level='range_start', template='plotly_dark', trace_kwargs=dict( colorscale='Viridis', colorbar=dict( title='Total return', tickformat='%' ) ) ) fig.show() 

https://reddit.com/link/hxl6bn/video/180sxqa8mzc51/player
From signal generation to data visualization, the example above needs roughly a minute to run.

vectorbt let's you
The current implementation has limitations though:

If it sounds cool enough, try it out! I would love if you'd give me some feedback and contribute to it at some point, as the codebase has grown very fast. Cheers.

Renewable energies, particularly hydro, are powering a growing share of Bitcoin and other proof-of-work mined cryptoassets. The ‘3rd Global Cryptoasset Benchmarking Study’ shows that the share of renewables in the total energy consumption of proof-of-work miners globally has reached 39%. This compares with the 28% share recorded in the 2nd benchmarking study in 2018 and... If bitcoin’s price drops below the cost associated with mining one bitcoin, the entire workflow becomes unprofitable for the miners. Back in December, Sam Doctor, the head of data science at Fundstrat Global Advisors, said; Our model suggests the cash cost of mining each BTC on the Antminer S9 is now $4,500, down from $5,300 in September. This price was even more than a bitcoin’s price ... Mining Bitcoin by yourself is not profitable, but renting out your hash rate could be, and mining other cryptocurrencies could also be profitable. Leaving me with an answer of maybe. Footnotes *Note that revenue is based on actually mining a bitcoin. If you mine by yourself you gain either nothing or an entire Bitcoin (and the vast majority of the time you'll get nothing). If you join a large ... Development. This stage of the mining process requires establishing a path to the mineral deposit. That path, however, requires more than excavation. In order to even begin work, mining rights must be acquired, access roads must be constructed to help workers navigate the site, and a power source must be established. Production. Once these elements are obtained, the physical mining process ...
