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, margin, 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
|
||||
|
||||
funding -> 1of2 CC global CC address and dealer address, exposure tokens to global 1of2 assets CC address
|
||||
pricebet -> user funds and exposure token to 1of2 address.
|
||||
pricewin -> winnings from dealer funds, exposure token back to global address
|
||||
priceloss -> exposuretoken back to global address
