1-78: Consider additional improvements and clarifications.While the main change has been addressed, here are some suggestions to enhance the overall function:
Error Handling: The function raises an exception when no existing perpetual position is found. Consider adding a more graceful error handling mechanism or documenting this behavior clearly in the function description.
Documentation: The function's description could be expanded to include information about the
dydx_get_weighted_average,dydx_trim_scale, anddydx_perpetual_position_and_order_side_matchingfunctions. This would provide better context for future maintainers.Performance: For frequently called functions, consider adding an index on (
subaccountId,perpetualId,openEventId) if not already present, to optimize the initial SELECT query.Could you provide more context on:
- The frequency of calls to this function?
- The typical volume of data it processes?
- Any performance benchmarks or requirements for this function?
This information would help in determining if any further optimizations are necessary.

47-47: Approved: Entry price calculation reverted as intended.The change from
perpetual_position_record."sumOpen"toperpetual_position_record."size"in thedydx_get_weighted_averagefunction call aligns with the PR objective to revert the previous change in entry price calculation.To ensure the change doesn't introduce unintended consequences, please verify:
- The accuracy of entry price calculations, especially for positions that have been partially closed and reopened.
- The consistency of this change with other parts of the codebase that may rely on the entry price calculation.
Consider adding a comment explaining the rationale behind using
sizeinstead ofsumOpenfor future reference. For example:-- Using 'size' instead of 'sumOpen' for entry price calculation to accurately reflect the current position entry_price := dydx_get_weighted_average( perpetual_position_record."entryPrice", perpetual_position_record."size", price, size );indexer/services/ender/src/scripts/helpers/dydx_liquidation_fill_handler_per_order.sql (1)
203-203: Approved: Correction to entry price calculationThis change reverts the entry price calculation to use
perpetual_position_record."size"instead ofperpetual_position_record."sumOpen"when calculating the weighted average. This modification aligns with the PR objective and likely provides a more accurate representation of the current position size for the entry price calculation.The impact of this change:
- It corrects the entry price calculation, addressing the issue introduced in PR Revert "[CT-629] Fix entryPrice calc" #2425.
- The resulting
entry_pricewill now be based on the actual size of the position rather than the sum of open amounts.- This change ensures that the entry price more accurately reflects the current state of the perpetual position.
To ensure this change doesn't introduce any unintended side effects, please verify that:
- All other occurrences of
dydx_get_weighted_averagein the codebase use the correct size parameter.- The
perpetual_position_record."size"is always up-to-date and accurately represents the current position size.You can use the following script to check for other occurrences:

140-141: Update in default perpetual position sizeThe
sizeproperty ofdefaultPerpetualPositionhas been changed from '10' to '5'. This change affects the initial state of the perpetual position used in tests.This change is likely intentional and may be part of adjusting test scenarios to match updated business logic or requirements.
395-397: Consistent updates to test expectationsThe test expectations for
sumOpenand other calculations have been updated to reflect the change in the initial position size. This ensures consistency with the modifieddefaultPerpetualPosition.These changes maintain the integrity of the test cases and accurately reflect the new initial conditions.
Line range hint
1-1180: Summary of changesThe primary change in this file is the update to the initial perpetual position size from '10' to '5'. This change has been consistently applied throughout the test cases, with appropriate adjustments to calculations and expectations. The core functionality and structure of the tests remain unchanged.
These changes appear to be intentional and well-implemented, maintaining the integrity and purpose of the test suite while adjusting for new initial conditions.

442-442: Approved: Consistent use ofsumOpenfor perpetual position calculationsThis change correctly updates the
expectPerpetualPositionfunction to usedefaultPerpetualPosition.sumOpeninstead ofdefaultPerpetualPosition.sizewhen calculating the expectedsumOpenvalue. This modification ensures consistency with the changes made to thedefaultPerpetualPositionobject and more accurately reflects the intended behavior of the perpetual position calculations.
141-142: Verify the relationship betweensizeandsumOpenThe
sizeproperty has been reduced from '10' to '5', but thesumOpenproperty remains at '10'. This results insumOpenbeing larger thansize, which might be intentional but could also be an oversight. Please verify if this is the desired behavior for thedefaultPerpetualPositionobject.✅ Verification successful

nit: Possible to add a test-case where perpetual position size is = negative size of fill to test that the previous error case couldn't happen again?
