OnBarClose() and indexing of data points

[Sidhartha]

Hi All,


Question. When OnBarClose() is called, are we still 'in' the bar that just closed or have we moved onto the next (new) bar for the purposes of indexing of data points.

For example, it's just struck 16:00. And the OnBarClose() method of 5 min bars has been called because the 15:55 bar has just ended. IF I now look at Open[0] will I be looking at the open of the 15:55 bar or the open of the new and in progress 16:00 bar...?

Many Thanks

OnBarUpdate() is called in a backtest on the close of the bar. In real-time it will depend on the property CalculateOnBarClose. If true, then on the close of a bar. If false, then on each incoming tick for that bar.

Thanks Ray. Yup, I got that.

Just for clarity... From the point of view of historical data (i.e. backtesting) OHLCV data is not produced for any bar until it closes... is that correct...??

i.e. in my example, in backtest it's 16:00... if I look at Open[0] it will give me the open of the 15:55 bar...??

In backtest, Close[0] will give you the close price for the bar with the time stamp provided by Time[0].

So if Time[0] is 16:00, you will get the close of the bar for that time stamp.

Thanks Ray. That's what I need.
