Order Lifecycle And Reconciliation

IMC keeps order execution and exposure verification explicit.

Open Flow

1. Read current mode context from funds or analyzer status.
2. Send placeorder, placesmartorder, basketorder, splitorder, optionsorder, or optionsmultiorder with mode precondition fields.
3. Verify the broker order with orderstatus.

Close Flow

1. Send closeposition with the strategy name and mode precondition fields.
2. If the close response succeeds, read positionsopen for the same strategy, symbol, exchange, and product.
3. Treat positionsopen.quantity = 0 as zero-exposure proof.
4. Treat closeposition returning NO_STRATEGY_EXPOSURE as zero-exposure proof.
5. If neither proof is available, keep the local client state pending reconciliation rather than assuming the position is still open.

Why positionsopen Exists

positionsopen is not an order endpoint. It is a strategy-scoped reconciliation read. It answers one question: "does this strategy still have exposure for this symbol/product?"

Because it is read-only, it is mode-checked but does not create a protected operation lease.

Protected entries

Use protected-order lifecycle to place broker-managed TP/SL with entry. Protected book v2 supplies actual cumulative fill evidence; no exposure alone must not release margin or invent a fill/P&L. Strategy closes verify linked protection cancellation before closing; generated working/uncertain exits block unsafe closes. Protection failure does not automatically liquidate the entry.
