foreign exchange交易存在风险，正如我们已看到的，保证金交易可以极大地放大利润率或亏损率。Foreign exchange transactions需要时刻警惕，交易者需要牺牲休息或休闲娱乐时间。

Orders executed immediately at the current exchange rate are called market orders. But traders can set some automatic instructions at certain predetermined prices to control losses and consolidate their gains.

　　?Stop loss order(STOP)This is an instruction that automatically clears the warehouse when the buyer's bid or the seller's asking price reaches the predetermined price.

If you hold multiple positions, you can set up a stop loss order below the current exchange rate. Once the market price falls below the stop loss trigger level, the order will be activated and your long position will be automatically closed.

If you hold a short position, you can set a stop loss order above the current price level. Once the seller's asking price rises to the trigger price, the order will be activated.

　　“Trailing Stop ”It is an instruction set when entering the profit stage. This strategy is beneficial for locking in profits. As positions become increasingly profitable, by raising the stop loss trigger price, traders can ensure that they can still achieve most of their book returns in the event of a market reversal.

The problem with stop loss orders is that in volatile markets, exchange rates may break through the stop loss trigger price, making it impossible for stop loss orders to be executed at precise stop loss levels.

　　?Profit instruction(TPO):Opposite to stop loss orders (i.e. limiting returns).TPOThis means that once the current exchange rate exceeds the set limit, the position will be closed. For short positions,TPOThe instruction will be set below the current exchange rate, while for long positions, the opposite will apply.

　　?Limit order: A buy or sell order that will be activated when the current exchange rate exceeds some predetermined limit prices.
　
When the exchange rate falls below a predetermined limit, traders may set“Buy”Limit order. On the contrary, when the exchange rate exceeds a predetermined limit price, traders may set“Sell”Limit order.

Price limit order(Limit)It can be valid for a specific period of time (such as one day or one month), or“Valid before cancellation”（GTC）. The daily effective limit order is valid for the remaining time of the trading day, unless executed before the end of the trading day.GTCThe price limit order remains valid until the transaction is completed, unless the account holder issues an instruction to cancel the order.

　　?If one instruction is valid, the other instruction will be cancelled(OCO):This is a combination of stop loss orders and limit orders (or two limit orders) set up at both ends of the price difference. When one instruction is triggered, another instruction is terminated.

For long positions, stop loss orders will be placed below the market spread, while limit sell orders will be placed above the market spread. If the exchange rate of the base currency exceeds the limit of the limit order, the position will be automatically sold, and a stop loss order is no longer needed, so the stop loss order will be cancelled. On the contrary, if the exchange rate drops to the stop loss order triggering price, the position will be closed, and there is no need for a limit order at this time.

For short positions, stop loss orders will be placed above the market spread, while limit orders will be placed below the market spread. If the exchange rate rises to the stop loss trigger level, the position will be closed and the limit order will be cancelled. If the exchange rate drops to the trigger price of the limit order, the limit order will be activated, the short position will be repurchased and closed, and the stop loss order will be cancelled.
