I had suggested some months ago to Ninjatrader that they give the option of assigning an instrument to a chart without having it plot at all, so that it would not have any effect on the scaling of other indicators. They did not see the merit of that suggestion. Maybe if a few hundred more people asked for it......
Imagine being able to do that for instruments having different time frames, that would be sweet.
Well done !
Please keep in mind that the Gomfolder stuff isn't a requirement : it's only to be used if you're not satisfied with the default file location, which is in your "My Documents" folder.
Also look through the Buy/Sell Volume thread on the Ninjatrader forums.

Latest beta of NT7 is now version 7.007. Not a good idea to keep using Beta 1 if anyone is doing so.
Thank you Zondor, I just want open charts and get historical data populated from the datafeed just like in IRT or MD without need to record. I guess its not possible yet.
Bid, Ask and Trade info are kept as different time series, with no synchronization between them. So the bid/ask info is pretty much useless... Looks like you're stuck with GomRecorder for persisting bid/ask info for some time :-)
Well it's more than that, the feature is also really required for indicators. I want a simple "enabled/disabled" switch for indicators, like there is for strategies. So I don't have to remove an indicator with 20 plots on it and then add it back just to test something.
>> that we simply can not backfill stuff made using onmarketdata() in 7 like we could not in 6.5
Your understanding is correct.
and post 21
Guys,
Let me outline the opportunities and limitations of the new historical bid/ask feature.
- you could have multiple bid/ask/last series on your indicator/strategy
- the historical bid/ask series would hold ALL bid/ask events sent out by the exchange. Thus, it would NOT be the bid/ask at the time a trade went off
- on the historical part they would be replayed by OnBarUpdate
- OnMarketData only would be triggered realtime
- on historical replay the series are synced by their timestamp
- timestamps in NT are down to 1 second granularity
- on realtime obviously the OnBarUpdate events on multiple series come in at the sequence as sent out by the exchange
So:
- the EXACT sequence of a mix of bid/ask/last events will NOT be maintained while processing the historical data from multiple series
- the EXACT sequence of the bid/ask/last events by themselves WILL be maintained while processing the historical data from multiple series
However, on events with DIFFERENT timestamps the sequence always IS maintained.
