reduced CalcTWAP to only one snapshots range

[trinitys7]

Purpose / Abstract

• Closes CalcTWAP: can be reduced to only one snapshots range. #1553

Summary by CodeRabbit

• Refactor
  • Improved the efficiency of processing snapshots in the time-weighted average price (TWAP) calculation logic.

Walkthrough

The update in the CalcTwap function within twap.go streamlines the processing of snapshots by directly assigning values from the iterator, incorporating a count variable to monitor the number of snapshots, and refining the circuit-breaker logic for scenarios with a single snapshot. This change aims to enhance efficiency and accuracy in calculating time-weighted average prices (TWAP).

Poem

In the realm of code, where logic intertwines,
A rabbit hopped, through the lines of times.
With a tweak and a hop, it refined the flow,
Where snapshots align, in a seamless row.

🌟 "To calculate TWAP, with grace and ease,
Let's count and assign, like a gentle breeze."
In the heart of the code, where changes embrace,
A rabbit's touch, leaves a whimsical trace. 🐇

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit-tests for this file.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit tests for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository from git and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit tests.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

• 59-59: Introducing a count variable to track the number of snapshots processed is a good practice for clarity and can be useful for debugging or further logic enhancements. This addition aligns with the goal of simplifying the function's logic.
• 62-62: Incrementing the count variable for each snapshot processed is straightforward and effective. However, ensure that this logic correctly accounts for all relevant snapshots, especially in edge cases where snapshots might be skipped due to identical timestamps.
• 98-99: The updated circuit-breaker condition to handle cases with only a single snapshot or when cumulativePeriodMs equals zero is a logical improvement. It simplifies handling edge cases, ensuring that the function can gracefully handle scenarios with minimal data. However, verify that this change does not inadvertently affect the accuracy of TWAP calculations in edge cases.

[coderabbitai]

The direct assignment of values from the iterator to snapshots simplifies the logic for collecting snapshot data. This change should improve readability and potentially performance by eliminating explicit iteration. However, ensure that the iter.Values() method efficiently handles large datasets without significant memory overhead.
