Leveraged Futures Exchange for Simulated Trading (LFEST)
:warning: This is a personal project, use a your own risk.
:warning: The results may not represent real trading results on any given exchange.
lfest-rs is a blazingly fast simulated exchange capable of leveraged positions. It gets fed external bid ask data to update the internal state and check for order execution. For simplicity's sake (and performance) the exchange does not use an order book. Supported futures types are both linear and inverse futures.
Order Types
The supported order types are:
- market - aggressively execute against the best bid / ask
- limit - passively place an order into the orderbook
Performance Metrics:
The following performance metrics are available through AccTracker struct:
- win_ratio
- profit_loss_ratio
- total_rpnl
- sharpe
- sortino
- cumulative fees
- max_drawdown_wallet_balance
- max_drawdown_total
- num_trades
- turnover
- trade_percentage
- buy_ratio
- limit_order_fill_ratio
- limit_order_cancellation_ratio
- historical_value_at_risk
- cornish_fisher_value_at_risk
- d_ratio
Some of these metric may behave differently from what you would expect, so make sure to take a look at the code.
How to use
To use this crate in your project, add the following to your Cargo.toml:
[dependencies]
lfest = "0.19.1"
Then proceed to use it in your code.
Here is a basic example:
//! Example usage of Exchange using external trade data.
//! A randomly acting agent places market buy / sell orders every 100 candles
extern crate log;
use ;
use load_prices_from_csv;
use ;
use Instant;
/// analyze the resulting performance metrics of the traded orders
TODOs:
- proper liquidations
- add order filter configuration such as min_qty and qty_precision
- add max_num_limit_orders to config
- impl Display for Side and FuturesType
- add optional order filtering such as
- PriceFilters:
- min_price
- max_price
- tick_size
- SizeFilters:
- min_size
- max_size
- step_size
- PriceFilters:
- add config option to disable acc_tracker, which will save a bunch of RAM
