Module resample 

Higher-timeframe candle resampling.

Aggregates base-timeframe candles into a higher-timeframe (HTF) series using standard OHLCV rules:

• Open = first constituent bar’s open
• High = max of constituent highs
• Low = min of constituent lows
• Close = last constituent bar’s close
• Volume = sum of constituent volumes
• Timestamp = last constituent bar’s timestamp (marks bar completion)

Functions

base_to_htf_index

Map each base-timeframe index to the most recently completed HTF bar index.
