Bars.GetBars Method

[Serialcoder]

Hi,

I'm trying to use the undocumented Bars.GetBars method to backfill historical ticks. I had it working in NT7.

Currently my example code in 8 looks like this and the code runs, but does not really produce results.

   BarsPeriod bpAsk = new BarsPeriod();
                bpAsk.BarsPeriodType = BarsPeriodType.Tick;
                bpAsk.MarketDataType = MarketDataType.Ask;
                bpAsk.Value = 1;
                bpAsk.BaseBarsPeriodValue = 1;


                

                Bars.GetBars(dBars.Instrument, bpAsk, this.beginTime, this.toTime, bars.TradingHours,
                   bars.IsDividendAdjusted, bars.IsSplitAdjusted, bars.IsTickReplay, bars.IsResetOnNewTradingDay,
                   LookupPolicies.Provider, MergePolicy.UseGlobalSettings, true, null, AdBars.IsRolloverAdjusted, null, GetBarsCallBack());

And the Callback method...Any help appreciated on how to use this, currently I just make it return null so that it compiles and runs.

  private Action<Bars, ErrorCode, string, object> GetBarsCallBack()
        {
            return null;
        }

Thanks a lot.

Hello Serialcoder,

Thanks for your post and welcome to the Ninjatrader forums!

Correct, in NinjaTrader 7 it is undocumented.

In Ninjatrader 8 you would want to use BarsRequest which is documented. Please see: http://ninjatrader.com/support/helpG...arsrequest.htm

(Note that while the link shows in the Helpguides's Add On area, the comment in the example advises: "...The concept can be carried over to any NinjaScript object you may be working on."
