[amibroker] Re: How can you test to see if an array crossed a scalar value?

["Mike" <sfclimbers@xxxxxxxxx>]

It's not wasteful. AFL was desgined to do exactly that.

CrossUp = Cross(MyArray, 50);
CrossDown = Cross(50, MyArray);

for (i = 0; i < BarCount; i++) {
...
}

Better yet, skip the loop altogeather and just use array manipulations to grab interesting values at the time of a particular event. See ValueWhen function:

I'd like to test the latest (newest) value in the array to see if it has crossed below or above a scalar number (say the number 50.0). Is there a good way of doing this built in? It seems the Cross() function tests an array against an array. I could build an array that has all values of 50.0, but that seems wasteful.
