Funds work like with dice, ie. there is a Prices plan that traders bet against.
PricesOpen -> oracletxid start with 'L' price, leverage, amount
funds are locked into global CC address
PricesFunding oracletxid, priceaveraging, maxleverage, funding, longtoken, shorttoken, N [pubkeys]
PricesBet -> oracletxid start with 'L', leverage, funding, direction
funds are locked into global CC address
it can be closed at anytime by the trader for cash settlement
the house account can close it if rekt
Implementation Notes:
In order to eliminate the need for worrying about sybil attacks, each prices plan would be able to specific pubkey(s?) for whitelisted publishers. It would be possible to have a non-whitelisted plan that would use 50% correlation between publishers.
delta neutral balancing of risk exposure
delta neutral balancing of riskexposure: fabs(long exposure - short exposure)
bet +B at leverage L
absval(sum(+BLi) - sum(-Bli))
validate: update riskexposure and it needs to be <= funds
PricesProfits: limit withdraw to funds in excess of riskexposure
PricesFinish: payout (if winning) and update riskexposure
need long/short exposure assets
exposure tokens + funding -> 1of2 CC global CC address and dealer address
pricebet -> user funds to 1of2 address. exposuretoken to exposure address
pricewin -> winnings from dealer funds, exposure token back to 1of2 address
priceloss -> exposuretoken back to 1of2 address
