Difference between 2 levels (change in Avg line)

[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.

Hello mrre1,

Your inquiry says NinjaTrader 8, but you have posted in the NinjaTrader 7 section of the forums.

Further, you have another post in the NinjaTrader 8 section of the forums.

Is this a duplicate post, or did you intend to ask for NinjaTrader 7?

Below is the code for NinjaTrader 7.

private int changeAmount = 4;

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