The 430 margin was based on XAU/USD ounce, not on 1000 ounce. There was a floating losses of 100 thousand according to the latest data.

Hantec notified that the margin would be adjusted on October 21st, while mine was modified on 19th. The margin before the adjustment was: 1490.53x43=430 On 19th, the margin became: 1490.53x43=609.56 The closing price the day was: 1490.53x43=640.9 The margin on 21st: 1484.66x43=638.4 The price difference between 18th and 29th: 640.9-638.4=2.5xauusd The price of USD was 1770 with 43 lots, i.e. usd=43x1770=76110, 76110/100=-761.1 For example: 1400x43=602，1450x43=623.5623.5-602=21.5 Thus I reckoned that the 430 margin was based on 1000 ounce, while it was on XAU/USD. 430x43=184.9, 1000x43=430, 1800-430=1370, 1000-430=570, 1450-430=1020, 1450-609=841, 609+430=1039 Min: 1410.34=606.44 Min: 1400x43=602, 1410.34x43=606.44 MAX: 1429.25x43=614.6 So the price couldn’t be down to 1420. My position was modified into 430 from 1000 ounce.
