Recent transations based on settlement price

[Klapeyron]

Describe the bug Right now frontend displays recent transactions based on latest created positions on given market, which is realized by following query:

subscription SubscribePositions($marketId: String!) {
        positions(where: { market: { id_eq: $marketId } }, limit: 10, orderBy: timestamp_DESC) {
            id
            price
            timestamp
            quantity
        }
    }

The thing is, that positions once created are immediately marked to market with known oracle price, so price that is in this position does not represent creation price of the position.

Position Creation and Position M2M are two independent operations represented by separate events. Right now, for Market.PositionCreated new record is created in the database and for Market.PositionMarkedToMarket position price is updated to oracle price.

Expected behavior

• Indexer provides information about latest transactions with prices before M2M settlement
• Additional data stored in database for this task follow market lifetime (Market.MarketCreated, Market.MarketRemoved) events

Screenshots

Additional content

• Example with market.createPosition call
• Production indexer deployment graphql api
• Sample query that extracts some real data from production deployment:

  
  query LatestPositionsOnGivenMarket {
  positions(where: {market: {id_eq: "9223372036854775809"}}, limit: 10, orderBy: timestamp_DESC) {
  id
  price
  timestamp
  quantity
  long
  short
  status
  }
  }
