# Gap Filling Guide

**Status**: Planned for v6.0.0+

**Current Capability**: Automatic gap detection implemented and working

**Pending Implementation**: REST API-based gap filling

## Overview

This guide will document the comprehensive gap filling workflow once implemented in v6.0.0+.

## Current Gap Detection (Available Now)

Gap detection is fully implemented and operational:

- Automatic timestamp sequence analysis
- Timeframe-aware gap detection (1s to 1d intervals)
- Gap boundary identification
- Gap reporting in validation results

See [Validation Overview](../validation/OVERVIEW.md) for gap detection capabilities.

## Planned Gap Filling (v6.0.0+)

The following features are planned for future releases:

- Automatic gap filling via Binance REST API
- Batch API requests for efficiency
- Safe file merging with atomic operations
- Zero-gap guarantee enforcement

## Interim Solution

Until automated gap filling is implemented, gaps can be addressed by:

1. Collecting additional data ranges that overlap gaps
2. Using validation reports to identify specific gap periods
3. Manual data collection for critical missing periods
