Dropped bars

[jerimac2]

I'm running a NinjaScript strategy that uses 1-minute bars for 3 different ETFs. I'm using Print statements on 30-minute intervals to track prices, indicators, and other diagnostics, and I noticed that the bar counts for the 3 1-minute streams are significantly different. All 3 funds occasionally drop a bar, and one fund had a full day without an OnBarUpdate event.

Are there normal conditions under which NinjaTrader doesn't receive a bar update for a stock/ETF? Both my Barchart.com feed and my TDAmeritrade feed drop bars.

jerimac2,

NinjaTrader itself will never drop any data coming in from the data provider. If you have data flowing, it will be presented in NinjaTrader. It is like a radio receiver in this regards. Suggest you check your connection and try to reload your historical data.
