Add()... causing cs 1502 & 1503 - NT7

[Art09]

Hi,
I'm trying to add a longer term MACD to my indicator. Below code is copied from NT7 strategy sample, but still causing errors:

protected override void Initialize()
{
// Add 10 minute Bars object to the strategy
Add(PeriodType.Minute, 10);
Add(MACD(5,20,30)); // This line causing errors
//Add(SMA(50)); -- orig NT code also causing errors if uncomment --

CalculateOnBarClose = true;
}

If I remove Add MACD and uncomment the original NT code: Add(SMA(50)); this will cause the same errors. The strategy sample compiles w/out errors.

I just noticed another problem: the Add(PeriodType.Minute, 10); causing all my arrows up/down dissapearing from the chart. If I comment this line - all works fine.
Thank you.
Regards, Art.

Hi Art,

Yes, you can add Indicators to strategies for visualization but you can't use this approach in an indicator.

You can call the MACD indicator in your custom indicator if you want to calculate a value on it. If you want to visualize it, then you need to set plots in your indicator. Your options for setting plots are:

• Duplicating the MACD logic in your new indicator.
• Set plots based on called MACD value.
• Creating a copy of MACD indicator (Right Click Save as from MACD editor) and working from that.

Hi,
How would I calc. values or get a direction-rising/falling of higher time frame MACD in my custom indicator? If higher time frame MACD is rising then return 1... and pass this value to my custom indicator... I'd like to be able to read values of higher time frame MACD from the indicator attached to my lower time frame chart. Is this possible at all? How would I do this? Is there lk global variable or such? Is there a sample or help on this topic please?
Thank you very much.

Yes, there's a sample multiTimeFrame indicator built into the platform. You can access by clicking Tools > Edit NinjaScript > Strategy > SampleMultiTimeFrame.

It's easy to access plots from other indicators. You just call the indicator and then the plot.
EX:
MACD(12,26,3).Avg[0]

If you want to access indicator values that are not plots, this sample can help:

Thank you. But that example is for the strategy that uses Add()... which did not work... The question is how can I check the higher time frame MACD value from the lower time frame indicator. For ex. call this inside the indicator on 5 min chart:
double 15minChartMacdVal = MACD(12,26,30).Avg[0]; // This should return the value of 15 min. chart MACD...
Thank you very much.

You need to work with multiple series scripts and Add() is used for this to add a secondary time frame, not indicator plots. The sample is relevant to what you're looking to do.

Documentation for multiple series scripts is available here:

Please review the sample and documentation for help working with multi time frame scripts. If you're having trouble implementing it, please share what you have written so far.
