Yes, you can have cross order positions which means, you can have a sell position and a buy position of the same pairs at the same time as long as these are held in the same account. In other words, you can participate in Forex trading without choosing either rising or falling market.
However, please note that cross orders can be affected by various factors such as swap rate and spread. Even if you have a complete set of matched orders, there may be a loss due to swaps and spread expansion.
We strongly recommended that you secure sufficient margin in your account to cover them when trading.
