What is the default time frame for NT?

[Kevin_in_GA]

Probably a really dumb question, but what is the default time frame for NT? Ticks?

I want to have all calculations run with COBC = true on 1 min bars. I doubt this is the default, so do I need to specify this with something like

Add(PeriodType.Minute, 1);

in the Initialize() section?

Kevin, it would strictly depend on which chart / series you run the study / script from.

Thanks. This is not exactly what I had expected, so it raises a few questions (just to better understand how NT works). Hopefully you can help me better understand the relationship and/or requirement for charts in an automated strategy.

My plan is to use a custom set of stocks (say 200 in total) and have the automated strategy scan these using a 1 min bar as the operative timeframe.

1. Does this require each stock to have an open chart?

2. Does a chart actually need to be open or does simply defining the time frame as 1 min suffice?

3. If a chart being open is a requirement for NT, would having only 1 chart open from the presected set allow for monitoring and trade execution for the entire list?

In essence, I just want my strategy to run against a set of pre-selected stocks without drawing too many objects which could impact performance.

You're welcome, a chart does not have to be open - you can create a MultiSeries strategy that would just Add() internally the bars series needed for your calcs / signals. Or another way would be starting the strategies on your instrument list in the Strategies tab in NT's Control Center - however keep in mind strategies started from there would not be visualized at all - it would be just a high performing mode to run strategies for execution sakes alone.

Hope that helps, have a good Friday,

Was what I had posted initially the correct code for this? If not, can you show me how this would be achieved?

Thanks again,

Yes, correct, this is how you would Add() a one minute bar. In your calculations in the OnBarUpdate() filter with BarsInProgress between the added series -
