state

tradeexecutor.state Python module in Trading Strategy framework.

Module description

Strategy execution state.

This module defines data structures used to manage the strategy execution.

• The internal data is a nested tree structure starting with tradeexecutor.state.state.State root class.

• The state includes portfolios, open and closed positions, trades being currently executed, deposits and withdraws, portfolio valuation events and such.

• The whole state must be serialisable as JSON, so that the JavaScript clients can read it.

• The same state structure is used for both backtesting (simulation) and live trading

• The application also internally stores its state as a flat file on the disk, see tradeexecutor.state.store

For an overview, see architecture documentation.
