Debugging with VisualStudio NT8

[tornadoatc]

Hello,

I am debugging an Indicator using VisualStudio in NT8 in a backtest. I am trying to understand the object structure of various PriceSeries like High[0], Low[0], etc.

If I have a simple line of code such as:

m_CurrWaveHigh = Math.Max(m_CurrWaveHigh, High[0]);

When I try to evaluate High[0] I can not determine where the price of the currentBar is being held.

For instance, I see High.Bars.CurrentBar = 22. But where is the High Price of CurrentBar 22 held? I thought it would be LastPrice but that is the LastPrice of Bar on Chart not the CurrentBar 22.

Thanks,

Hi tornadoatc,

When Calculate on bar close is set to True or the script is processing historical data, High[0] will refer to the close of the previous bar.
When Calculate on bar close is False and the script is processing realtime data, High[0] will refer to the high of the current bar.

If you are looking for high of the 22nd bar, you can use High[CurrentBar - 22].

The Close of the 22nd bar can be found with Close[CurrentBar - 22].

Hello Chelsea,

Thank you for your response. My question is specific to a backtesting scenario. I am stepping through my Bars via debugging through VS (looking through the High Properties using the VS debugging inspection tool) and the next instruction of my code says to compare High[0]. Doesn't this somehow get the High of the Current Bar being processed? If so, what property of the Bars.BarsSeries.??? would I find the HIgh of the CurrentBar being processed (e.g. Bar 22 in my example)?

Otherwise do I have this all wrong for strategy backtesting? And, you have to look at

High[CurrentBar]

for the High of current bar being processed and

High[CurrentBar - 1]

for the High of Previous Bar being processed for Historical data?

Or, something like

 High[BarsArray[0].Count - CurrentBar]

to get the High of Bar being processed in Backtest ?

Actually the logic seems to be processing correctly but I just can't see the values in the VS debugger to verify.

Thanks,

Hello tornadoatc,

When backtesting High[0] is the current bar being processed (as when you print High[0] you get the high of the bar being processed).

If you want the high of the bar 22 bars before the bar being processed, use High[CurrentBar - 22]. CurrentBar will be the bar number of the bar being processed.
