Closing an Order by Opposite Order

Request: close one order using another opposite-position order Sends a request to close a position by matching it with an opposite order.

---

Code Example

// --- Quick use (service wrapper) ---
// Closes one order by its opposite order.
svc.ShowOrderCloseByExample(ctx, 123456, 654321)

// --- Low-level (direct account call) ---
// Preconditions: account is already connected.
// ⚠️ This action closes trades — use on demo or with caution.

ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()

result, err := account.OrderCloseBy(ctx, 123456, 654321)
if err != nil {
    log.Fatalf("❌ OrderCloseBy error: %v", err)
}

fmt.Printf("Closed by opposite: Profit=%.2f, Price=%.5f, Time: %s\n",
    result.GetProfit(),
    result.GetClosePrice(),
    result.GetCloseTime().AsTime().Format("2006-01-02 15:04:05"),
)

🧩 Notes & Tips

• Same symbol required: Both tickets must be for the same symbol and opposite directions.
• Partial overlap: If lot sizes differ, only the overlapping volume is closed; the larger position remains with the residual volume.
• Ticket types: Tickets are int32 in your API; avoid mixing with uint64 types used elsewhere.
