datetime of a candle, open or close time?

bb2

Hello,

For a given CSV data, does backtrader assume that the datetime is the opening time of the candle? Is there any way to change that behaviour?

Thank you in advance

You probably need to enlighten us, with what you want. A candle has 4 points (OHLC) but a single timestamp. That doesn't have to do with days, minutes or the timeframe. It's a definition.

You are probably looking at using smaller timeframes.

@backtrader timestamp of the arrival time or timestamp of the closing time of the candle?

@backtrader in accordance with that, how does resampledata handle timestamps?

Let's assume I have 1 minute data with opening times starting from 18:00 until but not including 19:30, e.g.:

18:00 o h l c
18:01 o h l c
...
19:28 o h l c
19:29 o h l c

If I were to resample it to 30 minutes, what would be the timestamps of the resampled data?

I think what I am searching for is the rightedge attribute of resampledata. I will give it a quick shot.

figured it out. set boundoff=1 as arg of replaydata
