CFD差價合約常要留意的事

在fluent动网格计算过程中,经常会出现问题,想请各位精英帮助一下,也欢迎各位同学进行讨论。图1是动网格运动区域,呈一面扇形区域,扇形一边界可绕指定点进行转动,利用层变技术消减或生成网格。图2为出问题情况下的网格区域,从图中也可以看出它在指定位置并未发生网格消失。由此出现了负体积。经验证发现出问题时刻往往发生在运动边界速度最大值处,届时计算明显变慢,出现如图3所示的错误。捕获02.PNG 捕获01.PNG 捕获.PNG
后期也尝试了一些相似算例,在线程增大时,有时候会改善这种情况,但是有不确定因素。

差價契約CFD

3. 差價契約(CFD)交易可能遇到的風險?以及如何挑選較安全的交易商

它和期貨一樣,如果保證金不足或使用槓桿過大, 遇到市場波動加劇之時,容易會有被「斷頭」的風險, 因此盡可能避免將操作資金使用得太緊,或讓保證金水位充足會是一個較安全的做法。

A. 資金安全風險 (平台是否合法,出金服務是否有保障)

B. 流動性風險 (提供過大的點差報價)

4. 差價契約(CFD)交易最常遇到的問題

A2. 只要持單過夜就會產生「隔夜利息」,而利息是有正有負的,會視交易的商品利率不同而有所變動。以外幣為例: 每種貨幣都有本身的息率,當買入的貨幣息率高於賣出貨幣的息率,你就可以賺取過夜利息,反之亦然。

A4. 可以, 目前元大MoneyWin(MT5)支援iOS及Android版本,投資人可透過App Store或Google Play下載,便可隨時隨地進行差價契 約交易。

A5. 不行!槓桿交易商帳戶是獨立的, 就算已經開過期貨戶還是需要開槓桿交易商帳戶

5. 案例說明(槓桿風險):

在差價契約(CFD)交易中,因為具備槓桿的特性,所以帳戶風險是最重要的關鍵。意思就是你使用多少槓桿來進行交易。舉例來說,若只有1000美金,卻在交易時讓部位合約價值高達2萬(部位合約價值=交易單位x商品貨幣單位-以外幣保證金為例),就是使用了20倍的實質槓桿,只要行情波動1%,就等於部位損益波動200美金,即佔了帳戶資金的20%。反之如果你只使用了總資金的2%來進行交易,就會相對安全許多。因此在操作差價契約(CFD),必須特別留意自己使用的實質槓桿以及商品波動度,避免過大的槓桿造成損失或是見獵心喜讓自己曝在極大風險底下。
