# 限價

限價單係一個指示，要以指定價格或更好價格買入或賣出。唔似啲有條件嘅訂單，例如止蝕單、移動止蝕單或者止盈/止損組合——嗰啲會喺 goodcryptoX 伺服器上監察直到觸發條件達成——限價單會即刻傳送到交易所並直接放喺交易所嘅訂單簿上。

因為佢係存在交易所而唔係我哋嘅伺服器上，限價單嘅執行、成交行為或被拒，完全由交易所決定。一旦提交，就獨立於 goodcryptoX 運作：即使我哋嘅伺服器出現停機，你嘅限價單仍然會留喺簿上，並繼續按交易所嘅撮合引擎正常執行。

限價單可以用嚟直接入市或離場，亦都可以做為由 goodcryptoX 觸發嘅止限單（Stop Limit）同移動止限單（Trailing Stop Limit）嘅執行部分。網格及定投（DCA）機械人亦都依賴原生限價單。
