I need to Add() another Bars object to the same instrument

[pstrusi]

I need to add to the same instrument, another Bars object, where only changes "marketDataType".
For example I want to add all bid data to the script. According to NT help guide, this should go like this: Add(PeriodType periodType, int period). The problem with this is that doesn't allow "marketDataType" , so I can't add what I want.

How can I solve this?
by Add(string instrumentName, PeriodType periodType, int period, MarketDataType marketDataType) and under instrumentName put the same?

Is there other any way to Add a simple Bid series ?
I'd like to know which is best way to do this.

Thanks

Hello,

If you want to just add the Ask or Bid for the instrument you could use the following:

Add(Instrument.FullName, PeriodType.Tick, 1, MarketDataType.Ask);

or a string name:

Add("ES 12-15", PeriodType.Tick, 1, MarketDataType.Ask);

This would Add the instrument as 1 tick Ask series.

You could do the same for Bid choosing any Period and Interval you need.

I look forward to being of further assistance.
