From 345ad11ba33954bbd7f28e1ea27f571422e61ea1 Mon Sep 17 00:00:00 2001 From: discountry Date: Mon, 6 Apr 2026 20:05:03 +0800 Subject: [PATCH] refactor: enhance order handling and tracking in GridEngine - Introduced a clientOrderId system for better order identification. - Updated order creation logic to ensure unique clientOrderIds. - Improved order cancellation methods to maintain accurate current orders. - Added tests for new clientOrderId functionality and level state tracking. - Ensured that desired orders have an intent field set for clarity. - Enhanced snapshot functionality to include level states for grid lines. --- src/core/order-coordinator.ts | 2 + src/exchanges/aster/gateway.ts | 1 + src/exchanges/binance/gateway.ts | 3 + src/exchanges/dry-run-adapter.ts | 4 +- src/exchanges/order-handlers.ts | 3 + src/exchanges/order-schema.ts | 1 + src/exchanges/types.ts | 1 + src/strategy/common/grid-storage.ts | 17 +- src/strategy/grid-engine.ts | 1210 +++++++++++++++------------ tests/grid-engine.test.ts | 375 ++++++++- 10 files changed, 1067 insertions(+), 550 deletions(-) diff --git a/src/core/order-coordinator.ts b/src/core/order-coordinator.ts index ec0d04f..da8720d 100644 --- a/src/core/order-coordinator.ts +++ b/src/core/order-coordinator.ts @@ -134,6 +134,7 @@ type PlaceOrderOptions = { skipDedupe?: boolean; slPrice?: number; tpPrice?: number; + clientOrderId?: string; }; export async function placeOrder( @@ -180,6 +181,7 @@ export async function placeOrder( closePosition, slPrice: opts?.slPrice, tpPrice: opts?.tpPrice, + clientOrderId: opts?.clientOrderId, }); pendings[type] = String(order.orderId); log("order", `挂限价单: ${side} @ ${priceNum} 数量 ${quantity} reduceOnly=${reduceOnly}${opts?.slPrice ?
