ProgramGarden
ProgramGarden은 AI 시대에 맞춰 파이썬을 모르는 투자자도 개인화된 시스템 트레이딩을 자동으로 수행할 수 있게 돕는 노드 기반 자동매매 DSL(Domain Specific Language) 오픈소스입니다.
노드를 조합하여 워크플로우를 정의하고, 실행 엔진이 이를 자동으로 처리합니다. LS증권 OpenAPI를 메인으로 해외 주식/선물 거래 자동화를 지원합니다.

from programgarden import ProgramGarden

# 워크플로우 비동기 실행 (리스너 연결)

await job.stop()
Broker account trackers belong to the workflow job. Normal completion, stop(),
cancel(), and force_stop() cancel pending broker startup/history tasks, stop
account polling, and close each tracker's dedicated WebSocket. Late account PnL
callbacks do not restart work after shutdown. This cleanup also covers partially
initialized trackers and leaves other jobs running.
Scheduled cycles reuse the same broker account tracker, including pending startup.
A failed startup stops its tracker and closes its connection before a later cycle
may try again; no immediate retry or extra workflow node is introduced.
Already queued or in-flight PnL notifications have up to one second to finish
after account trackers stop, before listeners close. On timeout, cleanup logs the
pending count and cancels those tasks, allowing another 0.25 seconds for cancellation.
A listener that suppresses cancellation is reported and remains tracked; it cannot
hold job shutdown indefinitely. Delivery beyond this bounded grace is not guaranteed.
Overseas-stock OpenOrdersNode treats the observed terminal COSAQ00102 02679
empty envelope as open_orders=[] / count=0 without an error. The echoed date,
market and filters must match its current-day pending query, the empty detail
array must be explicitly present, and continuation must be terminal. This follows
the finance package's observed-response reference and StockAccountTracker;
02679 is not a generic success code. Missing, malformed, mismatched and failed
reads retain error / reason=fetch_failed so workflows can block new entries.
For one-shot workflows, an unhandled order_result.success=False returned directly
by a main-flow node makes the final job status failed and emits WORKFLOW_FAILED.
The original broker message remains in node diagnostics and the failure statistics.
Successful downstream nodes do not erase that rejection. reason="no_signal" stays
a normal no-op. Scheduled/resident workflows continue after a rejected cycle;
SplitNode and automatic iteration retain their existing item-error continuation
policies. Final failure is not inferred from cumulative errors_count or old logs.
Raised main-node exceptions retain the existing fail-fast behavior.
New-order nodes for overseas stocks, overseas futures, and Korea stocks expose
the catalog's result port as a list of outcome rows: {{ nodes.order.result }}
can feed TableDisplayNode directly. Each row copies the final order_result
and includes order_id from the existing top-level or nested order number.
Legacy order_result and order_id outputs are unchanged. The projection occurs
after fill confirmation, fractional-remainder annotation, and replay marking;
an accepted order is not promoted to a fill without confirmation. Rejections and
no_signal keep their original diagnostics/reason as an outcome row, with no
fabricated order number. Dry runs add a simulated row while retaining the legacy
flat simulation envelope; request/credential data is not copied into the row.
Automatic iteration merges these rows into one list. Implicit SplitNode collection
of a new-order result retains its legacy order_result row shape; explicit
nodes.order.result bindings always read the list. Modify/cancel nodes retain their
separately declared modify_result/cancel_result ports and are outside this change.
Explicit execution identities in local ledgers
WorkflowPositionTracker.record_fill(..., execution_id=...) can preserve a
broker-provided execution identity. Within one ledger/product/provider/mode,
order date and normalized order number, an identical replay returns the first
classification without changing FIFO or history. Conflicting facts raise
ExecutionIdentityConflictError. Positive numeric identifiers ignore padding;
opaque identifiers retain case. Missing, blank and zero identifiers retain legacy
behavior and are never inferred from time, price or quantity. Every pending
partial fill is retained while its order acknowledgement is being recorded.
The migration is additive and does not invent identities for existing rows. Callers must establish consistent identifier and timestamp semantics first; exchange execution numbers and broker execution numbers are not interchangeable. This ledger API alone does not reconcile finite workflows after their shutdown.
Standalone futures TC3 callbacks interpret s_b_ccd="1" as sell and "2" as buy,
matching the SDK contract. Unknown or blank side codes are logged and skipped
before any inventory write is scheduled. With an app order lifecycle handler,
TC3 still bypasses this legacy fill path: canonical REST reconciliation remains
the sole writer. This side correction does not establish an alias between TC3
and REST execution identities, dates, or times.
Futures monetary evidence
Futures workflow PnL events preserve native gross estimates separately from
accounting results. workflow_*, other_*, total_*, account and competition
monetary/rate scalars remain null when accounting evidence is unavailable.
pnl_by_currency contains gross price-change subtotals by contract currency;
monetary_positions retains their basis/status and unmodified, unconfirmed
broker_pnl_amount. No fee, FX, margin/equity return or verified contest score
is inferred from these estimates. Actual zero and negative amounts are retained.
currency is null for mixed or unavailable currencies. Consumers must handle
nullable monetary fields and must not coerce them to zero.
Personal workflow execution metrics
WorkflowPositionTracker.personal_metrics() reads retained SQLite trade_history
for the current product, provider and paper/live mode. Its independent
WorkflowPnLEvent.personal_metrics envelope retains stock realized PnL after all
positions close and counts distinct positive executed orders by valid stored
order date and normalized order number. Partial fills of one dated order count
once. This is the reporting runtime's retained workflow ledger, not a complete
account history or verified contest score. No credential/account generation is
claimed by this legacy local storage.
Stored stock realized PnL is gross long-only FIFO before fees. The reader validates sufficient recorded buys and consistency with stored results; mixed manual/product/provider/exchange FIFO ownership makes the affected symbol unavailable. Amounts remain separate by symbol/exchange, with currency null because the historical table has no currency evidence. No FX conversion or return denominator is invented. Futures executed-order counts are available under the same identity rules, but futures monetary results and portfolio MDD remain null: the retained FIFO lacks contract accounting and risk price windows are not equity curves. Invalid order identities also yield a null count with its reason.
The listener refreshes this evidence at most once per 10 seconds to avoid scanning
retained history on every price tick; reused observations retain their original
as_of. The cache is isolated to the actual tracker/product/provider/mode, and
other broker-node callbacks do not receive it. A newly recorded fill may appear
at the next refresh. Existing open-position PnL fields are unchanged. Core and
engine consumers must ship together to support the additive event field.
Stock read failures
Stock open-order queries include current-day orders (ThdayBnsAppYn="1").
OpenOrdersNode reports unusable COSAQ00102 responses with error,
reason="fetch_failed", and the original TR, HTTP status and broker response
fields in diagnostics. Its legacy empty payload/count remains for compatibility;
an error result is unavailable, not evidence of zero orders. A successful empty
response requires documented success plus parsed echo and aggregate blocks.
Unknown broker codes receive no inferred meaning.
Stock MarketDataNode preserves failed g3101 attempts under failures.
An entirely failed fetch returns error and reason="fetch_failed"; mixed
results retain usable values with _partial_failure and _failure_reason.
The existing exchange fallback and empty upstream no-signal behavior remain.
Futures master errors likewise report the observed catalogue and original broker
fields without inferring account entitlement, token or quota causes.
