Detection of Coterminious Multiple-Timeframe Bar Closures

[whitmark]

For the sake of clarification, assume I am using a lower timeframe primary bar interval, say 1 minute, and a higher timeframe secondary bar interval, say 60 minute. The market is somewhat illiquid so I can't always be assured that I will have a bar print each minute. Ideally, I would like to place a trade on the first primary bar (1 min) of the secondary bar interval (60 min) under certain conditions when:

if (BarsInProgress == 0)

     if (Times[1][0] != PrevTimes && Time[0] >= Times[1][0])
     {
          // do entry logic
          PrevTimes = Times[1][0];
     }
}

However, since the primary bar OnBarUpdate event is updated before the secondary OnBarUpdate event, this condition will never be true when BarsInProgress == 0 for this coterminous bar closing event, will it?

What is the best practice for determining when a lower timeframe primary bar is printing at the same time as a higher timeframe secondary bar for the purposes of placing trades on the primary timeframe without waiting for the next primary bar to print?

Thanks,

Whitmark

I guess you would need to know what the bar time of each 60 min bar is.

So if your session start time was 9:30 AM the first 60 minute bar would be 10:30 AM, so if you only wanted to trigger an entry on the 1st one minute bar of the 10:30 AM 60 min bar....then it could only trigger on the 10:31 AM 1 minute bar.

Knowing this, you could filter for valid bar times.

PS - Although this is not supported in the scope of NinjaScript, you can access the sesion start time via the property SessionBegin, it returns a DateTime structure.
