1, different currencies occupy different deposits. Take Europe and America as an example: the occupied deposit is about 139, so there is still 300-139 =161to resist risks. In mini's hand, each point is 1. In practice, different platforms have different stress leveling conditions. If it is a formal ALPARI MT4 platform, the system will force liquidation when the net capital is around 27.8 USD. If it is the GTS platform of FXSOL company, the position can be closed when the available margin is 0.

The account of $2,500, calculated in the same way, is 500- 139=36 1 dollar, which theoretically resists the fluctuation risk of 36 1 point. In fact, the system is strong and flat when the net value in MT4 is $27.8.

3. 1000 USD theoretically resists 86 1 point fluctuation,

The above calculation is based on the European and American exchange rate of 10 on the evening of June 25th, excluding the spread, because the spread is almost negligible in investment transactions.
