$STMX Unconsciously, the stmx incident has been going on for more than a year. The similarities here are that the positions have risen sharply and the long-short ratio has dropped sharply, both of which happened on weekends. Of course, this is not a simple repetition. After all, the conditions are different from last year. There is no enlarged futures-spot spread, no position restrictions by the exchange, and no modification of the funding rate frequency. Looking back at last year, reviewing the past and learning the new, it also faced delisting.
