Binance accounted for most of the new perpetual contracts in the 24 hours to 12:30 UTC on Oct 29. Our collectors first spotted six of them at 10:52 UTC, and each trades on Binance alone.

Those six are EWZS, SMR, OXY, AMGN, PFE and MELI. HTX added the other two on the list, JIO and PREDICT, first spotted at 05:52 UTC and also limited to that one venue.

None of the eight shows up on a second exchange among the six we follow.
