Trading decision based on different period type bars

[Logicwar]

I am working on a multiple instrument strategy. The different instrument bars (period type = minutes) are as expected added in the “configure state”. All is working as expected.

Now I want to add a check whether I will trade on not each individual instrument in the current day. The simple control that I would like to put in place is basically to check for each instrument if the momentum is above 0. But the period type that I would like to use for the indicator is “day”.

As the period type is different to the already added bars, I am not sure what I should do. From other posts, I see that I should add “day” period type bars for each instrument to check the momentum. Is this the right approach as I only need to run the test once per day? And then, how can I in the “OnBarUpdate” event avoid treating the added daily bars?

Thanks in advance for your advice/suggestion,
Eric

Hello Eric,

Yes, if you want to use 1 Day bars for the input series of an indicator, you would need to add that series with AddDataSeries() along with any other series you may have added.

The Closes or BarsArray with the index of that added series would be supplied to the indicator.
The help guide provides sample code.

To check momentum for each instrument once per day, adding daily bars for each instrument is a good approach. This way, you can calculate momentum based on the daily bars and make your trading decision accordingly.
In the "OnBarUpdate" event, you can use a simple condition to check if the current bar is a daily bar or a different period type bar. For example, you could use an if statement like this:
if (BarsInProgress == 0 && Bars.Period.Id == PeriodType.Day)
{
// Calculate momentum based on daily bars here
}
This way, you can ensure that your momentum calculation is only applied to daily bars and not to other period types. Good luck with your strategy, and if you ever feel indecisive about your trading decisions, you could always toss a coin to help you decide!
