fastmm::bt::ReplayOptions Struct Reference

#include <fastmm/backtest/replay.hpp>

Public Attributes
std::string	strategy
	empty -> the strategy recorded in the journal header
bool	verify = true
	compare every outbound message with the journal's Out* records
bool	session_from_journal = true
	Restore session epoch, quoting enabled, RNG seed and per-venue cancel-replace from a v2 header (a journal without them replays with the given configuration's values).
bool	param_updates = true
	Apply the journal's ParamUpdate records, their fields matched to the strategy's parameters by name (false: skip them and keep the configured parameters, a what-if run).
bool	allow_incomplete = false
	Replay a journal whose writer never closed it (no trailer) or whose last block is corrupt.

Member Data Documentation

strategy

std::string fastmm::bt::ReplayOptions::strategy

empty -> the strategy recorded in the journal header

verify

bool fastmm::bt::ReplayOptions::verify = true

compare every outbound message with the journal's Out* records

session_from_journal

bool fastmm::bt::ReplayOptions::session_from_journal = true

Restore session epoch, quoting enabled, RNG seed and per-venue cancel-replace from a v2 header (a journal without them replays with the given configuration's values).

param_updates

bool fastmm::bt::ReplayOptions::param_updates = true

Apply the journal's ParamUpdate records, their fields matched to the strategy's parameters by name (false: skip them and keep the configured parameters, a what-if run).

allow_incomplete

bool fastmm::bt::ReplayOptions::allow_incomplete = false

Replay a journal whose writer never closed it (no trailer) or whose last block is corrupt.

The events before the damage are intact, so a replay of them runs and the outbound comparison stops early; by default such a file is refused rather than compared against a stream that was cut off. fastmm-replay --allow-incomplete sets it and warns instead.
