Simple STO Cross problem

[gyoung]

I am trying to build a simple Sto cross indicator that alerts when the Sto 100 crosses below the 80 mark and I continue to get an index error.

The error is on the following line:
if (StochasticsFast(5,100)[0] < 80.0 && StochasticsFast(5,100)[1] > 80.0)

It has problems with "StochasticsFast(5,100)[1]" . Index out of range.

I have tried this with StochasticsFast(5,100).K[1] and quite a few other variations but have the same issue.

Is this the correct way to obtain the previous value or is there a better way.

Thanks,

The following link will provide you the answer - http://www.ninjatrader-support.com/v...ead.php?t=3170

Alternatively, you can use the following methods -

CrossAbove() - http://www.ninjatrader-support.com/H...rossAbove.html
CrossBelow() - http://www.ninjatrader-support.com/H...rossBelow.html

That worked. Thanks.

BTW - CrossAbove/Below will only work in situations where the %K and %D cross, not for when the Moving Average pass a threshold.

Nope. There are 2 signatures, one that takes 2 data series and one that takes a constant.

I need to read the documentation better next time :-(
You are correct.
