and [a - b < c]

"a" and "b" are the EMA and SMA of your choice, like ema(50,close) and sma(10,close). "c" is the difference between them of your choice - 0, 1, 2.5, etc.

But there are some wrinkles.

If you want only positive results (a is above b on the chart, or same thing, b is below a), then

and [a > b]

and [ a - b < c]

only negative results (a is below b):

and [a < b]

and [ a - b > c]

Note the change of the comparison operator for negative numbers from < (less than) to > (greater than). Also "c" would be a negative number: -1, -2.5, etc.

If you don't care whether the result is positive or negative, then you need the absval() function:

and [absval(a-b) < c]

Watch your parentheses with this one.

If you want to compare multiple mas, just repeat the appropriate statements for each comparison.
