vn.oanda的gateway接入
|
||
|
||
由于OANDA采用的是外汇做市商的交易模式，因此和国内接口方面有若干区别，具体如下：
|
||
|
||
* 行情数据反映的是OANDA的报价变化，因此只有买卖价，而没有成交价
|
||
|
||
* OANDA的持仓管理分为单笔成交持仓（Trade数据，国内没有）
|
||
和单一资产汇总持仓（Position数据）
|
||
|
||
* OANDA系统中的所有时间都采用UTC时间（世界协调时，中国是UTC+8）
|
||
|
||
* 由于采用的是外汇做市商的模式，用户的限价委托当价格被触及时就会立即全部成交，
|
||
不会出现部分成交的情况，因此委托状态只有已报、成交、撤销三种
|
||
|
||
* 外汇市场采用24小时交易，因此OANDA的委托不像国内收盘后自动失效，需要用户指定
|
||
失效时间，本接口中默认设置为24个小时候失效
