DataSeries, IDataSeries or MIN MAX?

[mokodo]

Hi

I'm trying to 'record' the highest and lowest reading for an indicator (MACD) but only once a set of conditions are met. Once I have the high or low I need to use them in IF statements.

I've played around with DataSeries, IDataSeries and MIN MAX but wondered if there was an established approach?

Thanks in advance

Hello,

Thank you for your post.

Have you tried the HighestBar() and Lowest() Bar methods?

This will return the highest and lowest value within the period you have specified.

Hi Matthew,

It's not really how the levels are being recorded (I've opted for SwingLow as per the example below), It's how I can limit the dataseries to storing the data only when a set of conditions are met.

This approach seems to work but I wondered if there is a recommended approach

if (MACD(12, 26, 9).Diff[0] > MACD(12, 26, 9).Diff[1]
&& MACD(12, 26, 9).Diff[0] > Swing(MACD(12, 26, 9).Diff, 0).SwingLow[0]
{
mACDhistlow.Set(Swing(MACD(12, 26, 9).Diff, 0).SwingLow[0]);
Print(mACDhistlow[0].ToString("Swing 0.0000000"));
}

Hello,

I see no problem with this. You're storing the value in a DataSeries object which will allow you to access this for later. This is essentially the same approach that is being used in our reference sample on this subject:

Matthew,

That's reassuring - thanks for the review
