It seems to me those long positions have been built (in substantial part at least) below $600. Since finex allows only 2:1 leverage they not be zhou-tonged above $300. Correct?
1) 2.5 lever, I thought.
2) You're forgetting the substantial interest rate on USD
3) There might be some 'safety net' for the margin requirements... don't know. Any active finex traders can clarify?
4) I hoped as well that most of them got in sub-600, but I'm not so sure anymore.
