What? How exactly are you planning to do that with the price of your token? What mechanism will you use for that? Because as for me, I don't understand what you are talking about. You will do that manually?
Via liquidations - kinda like BitMEX does it with XBTUSD, by liquidating traders according to mark price.
Suppose mark price goes up, but actual market price doesn't move. In this case, short positions will be liquidated anyway, and the forced buy orders will be placed at mark price, thus influencing the actual market price.
Think of "mark price" as a data feed that we provide to exchanges. It's true that we need to list the token on exchanges that support margin trading (e.g. Bitfinex, Huobi, or some of the new ones). That's why listing the token is our highest priority, as we've mentioned in the ANN post.
FYI, BTCV is already listed on
Voltex, although it doesn't support margin trading yet.
