IsFirstTickOfBar triggering each 15 seconds

[XTradeX]

Hi,

I put your sample indicator IsFirstTickOfBarAddedSeriesTest on GBPUSD 1 minute chart. I activated Show Tick Replay in the General Options->Market Data and Tick Replay on my data serie.

Why I receive OnBarUpdate event each 15 seconds with IsFirstTickOfBar = true ? This is the result from my script output window:

2020-09-16 10:54:45 | State: Realtime, BIP: 1, IsFirstTickOfBar: True, Bars TickCount: 1, Volume[0]: 11, BarsInProgress: 1, NewBar: True
2020-09-16 10:55:00 | State: Realtime, BIP: 1, IsFirstTickOfBar: True, Bars TickCount: 1, Volume[0]: 2, BarsInProgress: 1, NewBar: True
2020-09-16 10:55:15 | State: Realtime, BIP: 1, IsFirstTickOfBar: True, Bars TickCount: 1, Volume[0]: 12, BarsInProgress: 1, NewBar: True
2020-09-16 10:55:30 | State: Realtime, BIP: 1, IsFirstTickOfBar: True, Bars TickCount: 1, Volume[0]: 1, BarsInProgress: 1, NewBar: True
2020-09-16 10:55:45 | State: Realtime, BIP: 1, IsFirstTickOfBar: True, Bars TickCount: 1, Volume[0]: 8, BarsInProgress: 1, NewBar: True
2020-09-16 10:56:00 | State: Realtime, BIP: 1, IsFirstTickOfBar: True, Bars TickCount: 1, Volume[0]: 27, BarsInProgress: 1, NewBar: True
2020-09-16 10:56:15 | State: Realtime, BIP: 1, IsFirstTickOfBar: True, Bars TickCount: 1, Volume[0]: 2, BarsInProgress: 1, NewBar: True

Than you for your help.

Hello, thanks for your post, and welcome to the NinjaTrader forum.

It looks like you are printing the time stamp of the primary series, or you are running the script OnEachTick on a 15 second bar period. If that is the case, you will only have time stamps for each 15-second interval. So even if the first tick of the bar was at 56:14, it would print as 56:15

I look forward to assisting.

Hi Chris,

I verify the chart and I am on 1 minute chart. I tried with 2 minutes chart and I also get an event each 15 seconds.

Hello XTradeX, thanks for your reply.

My test is working fine. I get a print out on the 00 second each time the bar closes. Could you provide a test script?

protected override void OnBarUpdate()
{
    if(State == State.Realtime)
    {
        if(IsFirstTickOfBar)
        {
            Print(DateTime.Now);
        }
    }
}
