A GTT triggers and places its order during one trading session. On a later trading day:
1. Does `get_gtt(trigger_id)` / `get_gtts()` still return that GTT, with `orders[].result.order_result` including the order_id?
2. Can the order be retrieved with `order_history(order_id)`? Does it appear in `orders()` (the day's order book) on the later day, or only through `order_history`?
3. For how long are triggered GTTs and the orders they placed retrievable this way?
