AddDataSeries and OnMarketData

[johnok]

Hello,

Is it possible to get OnMarketData event for every DataSeries loaded ?

Hi johnok, thanks for posting.

Each added data series will be subscribed to OnMarketData and you can filter the context with the BarsInProgress property e.g.

OnMarketData:

if (BarsInProgress == 0)
{
//OnMarketData called for primary series
}

if (BarsInProgress == 1)
{
//OnMarketData called for secondary series.
}

Hi,

OnMarketData is an event which is called at every tick update but not bar, so i'm forced to use "Calculate.OnEachTick" and call every OnMarketData at every OnBarUpdate ?

Thanks

Hi johnok, thanks for your reply.

No, the indicator can still run OnBarClose, the Calculate property controls the frequency of OnBarUpdate, not OnMarketData.

Kind regards,

Sorry i don't understand how it's works.

I tried to use BarsInProgress with OnMarketData but that not seems to work.

See the picture.

Ok,

I found my error, i should load serie with string NQ 12-21 and not only NQ.

Is there a way to load a generic NQ(last contract) and not specify contract every time ?

Thanks

Hi johnok,

If the data feed you are using supports the continuous contract you can load "NQ ##-##". You can check if your data feed supports the continuous contract by loading "NQ ##-##" on a chart. If you plan to submit orders to this series, it must be hard-coded or taken as input from the strategy settings (excluding runs from the strategy analyzer).

Kind regards,
