Difference between 2 levels

[mrre1]

How would one code the following logic in NT8:

Change in value of Macd.Avg line (for example) from 20 bars ago to current bar, where the strategy only fires if the change is greater than x. For this example if the total change is 4 points, not a certain level.

Also is there a code snippet example for NT8 to replicate complex ATMs in backtesting?

Thanks.

Hello mrre1,

In the scope of the class:
private int changeAmount = 4;

In OnBarUpdate():
if (CurrentBar > 20 && Math.Abs(MACD(12, 26, 9).Avg[0] - MACD(12, 26, 9).Avg[0]) > changeAmount)
{
// execute code
}

Below is a link to an example that demonstrates trailing and chasing.
