Description:

hftbacktest 2.0.0

High-Frequency Trading Backtesting Tool
This framework is designed for developing high-frequency trading and market-making strategies. It focuses on accounting for both feed and order latencies, as well as the order queue position for order fill simulation. The framework aims to provide more accurate market replay-based backtesting, based on full order book and trade tick feed data.

Key Features
The experimental features are currently in the early stages of development, having been completely rewritten in Rust to
support the following features.

Working in Numba JIT function (Python).
Complete tick-by-tick simulation with a customizable time interval or based on the feed and order receipt.
Full order book reconstruction based on L2 Market-By-Price and L3 Market-By-Order (Rust-only, WIP) feeds.
Backtest accounting for both feed and order latency, using provided models or your own custom model.
Order fill simulation that takes into account the order queue position, using provided models or your own custom model.
Backtesting of multi-asset and multi-exchange models
Deployment of a live trading bot using the same algorithm code: currently for Binance Futures and Bybit. (Rust-only)

Getting started

Installation
hftbacktest supports Python 3.10+. You can install hftbacktest using pip:
pip install hftbacktest
Or you can clone the latest development version from the Git repository with:
git clone https://github.com/nkaz001/hftbacktest

Data Source & Format
Please see Data or Data Preparation.
You can also find some data here, hosted by the supporter.

A Quick Example
Get a glimpse of what backtesting with hftbacktest looks like with these code snippets:
@njit
def market_making_algo(hbt):
asset_no = 0
tick_size = hbt.depth(asset_no).tick_size
lot_size = hbt.depth(asset_no).lot_size

# in nanoseconds
while hbt.elapse(10_000_000) == 0:
hbt.clear_inactive_orders(asset_no)

a = 1
b = 1
c = 1
hs = 1

# Alpha, it can be a combination of several indicators.
forecast = 0
# In HFT, it can be various measurements of short-term market movements,
# such as the high-low range in the last X minutes.
volatility = 0
# Delta risk, it can be a combination of several risks.
position = hbt.position(asset_no)
risk = (c + volatility) * position
half_spread = (c + volatility) * hs

max_notional_position = 1000
notional_qty = 100

depth = hbt.depth(asset_no)

mid_price = (depth.best_bid + depth.best_ask) / 2.0

# fair value pricing = mid_price + a * forecast
# or underlying(correlated asset) + adjustment(basis + cost + etc) + a * forecast
# risk skewing = -b * risk
reservation_price = mid_price + a * forecast - b * risk
new_bid = reservation_price - half_spread
new_ask = reservation_price + half_spread

new_bid_tick = min(np.round(new_bid / tick_size), depth.best_bid_tick)
new_ask_tick = max(np.round(new_ask / tick_size), depth.best_ask_tick)

order_qty = np.round(notional_qty / mid_price / lot_size) * lot_size

# Elapses a process time.
if not hbt.elapse(1_000_000) != 0:
return False

last_order_id = -1
update_bid = True
update_ask = True
buy_limit_exceeded = position * mid_price > max_notional_position
sell_limit_exceeded = position * mid_price < -max_notional_position
orders = hbt.orders(asset_no)
order_values = orders.values()
while order_values.has_next():
order = order_values.get()
if order.side == BUY:
if order.price_tick == new_bid_tick or buy_limit_exceeded:
update_bid = False
if order.cancellable and (update_bid or buy_limit_exceeded):

if order.cancellable and (update_ask or sell_limit_exceeded):
hbt.cancel(asset_no, order.order_id, False)
last_order_id = order.order_id

# It can be combined with a grid trading strategy by submitting multiple orders to capture better spreads and
# have queue position.
# This approach requires more sophisticated logic to efficiently manage resting orders in the order book.
if update_bid:
# There is only one order at a given price, with new_bid_tick used as the order ID.
order_id = new_bid_tick
hbt.submit_buy_order(asset_no, order_id, new_bid_tick * tick_size, order_qty, GTX, LIMIT, False)
last_order_id = order_id
if update_ask:
# There is only one order at a given price, with new_ask_tick used as the order ID.
order_id = new_ask_tick
hbt.submit_sell_order(asset_no, order_id, new_ask_tick * tick_size, order_qty, GTX, LIMIT, False)
last_order_id = order_id

# All order requests are considered to be requested at the same time.
# Waits until one of the order responses is received.
if last_order_id >= 0:
# Waits for the order response for a maximum of 5 seconds.
timeout = 5_000_000_000
if not hbt.wait_order_response(asset_no, last_order_id, timeout):
return False

Migration to V2
Please see the migration guide.

Roadmap
Currently, new features are being implemented in Rust due to the limitations of Numba, as performance is crucial given the size of the high-frequency data.
The imminent task is to integrate hftbacktest in Python with hftbacktest in Rust by using the Rust implementation as the backend.
Meanwhile, the data format, which is currently different, needs to be unified.
On the pure Python side, the performance reporting tool should be improved to provide more performance metrics with increased speed.
Please see the roadmap.
