Transition

[carmiFR]

Hello,

In a real-time strategy, OnStateChange with State==State.Configure is the correct moment to request bid/ask series.
(I am not clear on how I should request and use bid/ask series, my question below ...)

Let's suppose some call to AddDataSeries had been done.

Then I guess some historical data is loaded (bid/ask series as the strategy requested) and Bars is filled with it.

In OnStateChange, when State==State.Configure, which variant of AddDataSeries should I use to get the maximum of historical bid/ask series available ?

Then, is it true to say that since Bars.GetAsk() or Bars.GetBid() allow to retrieve some past tick, a bid or ask available via GetCurrentBid or GetCurrentAsk will be transfered just after into Bars ?

How to get the maximum index for Bars.GetAsk() argument ? Bars.TickCount ? Bars.TotalTicks ?
I notice these property have setters. Can these setters be used in order to truncate the series ?


Thanks for your help

Hello carmiFR,

Thank you for your post.

Please visit the following link for information on using AddDataSeries() for Bid and Ask data: http://ninjatrader.com/support/helpG..._ask_serie.htm

The syntax to use for the full available data on the chart is as follows:
AddDataSeries(string instrumentName, BarsPeriodType periodType, int period, MarketDataType marketDataType)

You would not use GetAsk() or GetBid(). You would use Closes for example to pull the close. I recommend reviewing our details on multiple data series in your code for further details: http://ninjatrader.com/support/helpG...nstruments.htm
