Changelog

  • All parameter updates (borrowing/funding) which require the current pair price are no longer done using the request/callback pattern but using signed prices from the oracles directly, in a single transaction
  • Triggering orders (SL/TP/LIQ/LIMIT_OPEN/STOP_OPEN) is now also possible using signed pair prices in a single transaction (previous request/callback pattern still exists as backup)
  • This both saves gas (5 less transactions) and decreases execution time
  • Signed pair prices are validated, stored temporarily in storage, and cleaned up at the end of the transaction so the storage gas costs are refunded
  • Refactored aggregator answer validation (OHLC values) and median/outliers filtering into separate helpers, re-used for signed prices validation (exact same logic as in fulfill)
  • Updated SL_LIQ_BUFFER_P to 5%, from 10%
  • Refactored _limitSlDistance to account for open and close fees, now min is liqThreshold - 2 * totalPositionSizeP * leverage - SL_LIQ_BUFFER_P.
  • Updated withinExposureLimits to allow skew improvements even when skew is above max, uses new withinSkewLimits helper.
