Returns the engine's account registry and block facility.

Applies an account-adjustment batch for accountId.

accountId accepts an AccountId object or a number | bigint | string. adjustments is any iterable of AccountAdjustment objects or plain AccountAdjustmentInit literals. On success the result carries the produced outcomes; on rejection it carries the failing index and the rejects.

Errors

Throws ParamError/AssetError/AccountIdError when accountId or an adjustment in the batch is invalid. Re-throws the original error a custom policy callback threw, if any.

Applies an execution report across all policies and returns the aggregated post-trade result.

report accepts an ExecutionReport object or a plain ExecutionReportInit literal. A wrapper report is not consumed, so the caller may reuse the same object afterwards.

Errors

Throws ParamError/AssetError when report is neither a valid ExecutionReport nor a valid ExecutionReportInit literal. Re-throws the original error a custom policy callback threw, if any.

Returns the engine's runtime policy configurator.

Runs start- and main-stage checks in one step, returning a [JsExecuteResult].

order accepts an Order object or a plain OrderInit literal. A wrapper order is not consumed, so the caller may reuse the same object afterwards.

Errors

Throws ParamError/AssetError when order is neither a valid Order nor a valid OrderInit literal. Re-throws the original error a custom policy callback threw, if any.

Runs start- and main-stage checks as a non-mutating dry-run.

order accepts an Order object or a plain OrderInit literal. A wrapper order is not consumed, so the caller may reuse the same object afterwards.

Errors

Throws ParamError/AssetError when order is neither a valid Order nor a valid OrderInit literal. Re-throws the original error a custom policy callback threw, if any.

Runs start-stage checks and returns a [JsStartResult].

order accepts an Order object or a plain OrderInit literal. On success the result carries a single-use Request; on rejection it carries the rejects. A wrapper order is not consumed, so the caller may reuse the same object afterwards; a field-equivalent clone is retained as the request payload for later policy callbacks.

Errors

Throws ParamError/AssetError when order is neither a valid Order nor a valid OrderInit literal. Re-throws the original error a custom policy callback threw, if any.

Runs start-stage checks as a non-mutating dry-run.

order accepts an Order object or a plain OrderInit literal. A wrapper order is not consumed, so the caller may reuse the same object afterwards.

Errors

Throws ParamError/AssetError when order is neither a valid Order nor a valid OrderInit literal. Re-throws the original error a custom policy callback threw, if any.

Returns a fresh staged engine builder.
