v10.1 Update

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.
