Poloniex, a cryptocurrency exchange, announced that the exchange is allowing its customers the option to "trade two tokens at the center of the about the pending Bitcoin Cash (BCH) hard fork." Starting on November 7, users on Poloniex will be able to trade Bitcoin Cash ABC (BCHABC) and Bitcoin Cash SV (BCHSV).
This is not the first time an exchange has enabled pre-fork trading for cryptocurrencies. Back in October 2017, HitBTC users were able to trade futures for the SegWit2x token — the token behind the contentious "NO2x" debate. SegWit2x was ultimately called off due to the lack of consensus and support. Traders with SegWit2x token futures ended up owning unredeemable options. (Source: Circle)
