Bars.TickCount for previous bar

[cutzpr]

How do I get the Tickcount for the previous bar or any particular bar.

Hello cutzpr,

There is not series of tick counts. You would need to save this with custom C# logic.

You could save this to your own custom series.

I wouldn't mine the tick data that is used for Market Replay/Tick Replay. Is that data accessible?

Hello cutzpr,

The data used for TickReplay is historical tick data that is stamped by the provider with the ask and bid the moment the tick was produced.

To use this enable TickReplay in Tools > Options > Market data > Real-time > Show Tick Replay. Then enable TickReplay in the Data Series window for the chart or in the strategy parameters (if not on a chart). Then set Calculate to .OnEachTick in State.SetDefaults.

Below is a public link to the help guide.

In the script this causes OnBarUpdate to trigger for each tick historically and OnMarketData to update historically.

The ask and bid can be found in OnMarketData with marketDataUpdate.Ask/marketDataUpdate.Bid.

So essentially, regardless, I would still have to do a counter on the series. I couldn't be able to reference those ticks of the previous bar in the array even using tick replay.

Hello cutzpr,

There are no series of tick counts stored by NinjaTrader. You would need to create this.
