Referencing daily data within an intraday script

[jonesr227]

Forgive me of this has been asked before, but after reeading through the manual and doing a quick search of these forums, I unfortunately did not find the answer to my following problem.

I have an intraday script that runs using 5 minute data. However, the conditions on whether a trade is taken on any particular day is dependent on conditions dependent on daily data. Specifically, within my 5 minute data script I would like to find the ATR and Bollinger Bands of daily data which have look back periods of 20 days. I would appreciate some sample code of how this could be done.

Thanks,
Rick

After some thought, would the following work?

// in the variables section
private double atr20, boll20;
private boolean canTrade;

protected override void Initialize()
{
Add(PeriodType.Day, 1);
atr20 = ATR(BarsArray[1], 20)[0];
boll20 = Bollinger(BarsArray[1], 2, 20).Upper[0];

// example expression
canTrade = atr20 > boll20;
}

protected override void OnBarUpdate()
{
if (BarsInProgress != 0 || !canTrade)
return;
}


Is this the right way to do this? Also how do I make sure that NT sees at least 20 days of my 5 minute data for proper determination of the indicator values?

Almost there. You would need to check the condition in OnBarUpdate like:

protected override void OnBarUpdate()
{
if (BarsInProgress != 0
|| ATR(BarsArray[1], 20)[0} <= Bollinger(BarsArray[1], 2, 20).Upper[0])
return;
}
