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 simulated futures 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: - winratio - profitlossratio - totalrpnl - sharpe - sortino - cumulative fees - maxdrawdownwalletbalance - maxdrawdowntotal - numtrades - turnover - tradepercentage - buyratio - limitorderfillratio - limitordercancellationratio - historicalvalueatrisk - cornishfishervalueatrisk - dratio

Some of these metric may behave differently from what you would expect, so make sure to take a look at the code.
