Converging TEMAs

[XATPER]

I'm trying to locate stocks who's TEMA 10 and TEMA 20 are converging as the stock (and TEMAs) are falling. I have come up with the following script, but am not getting the desired results. Any help would be apprecitated.

Def T20 = TEMA(20);
Def T10 = TEMA (10);
Def T201 = TEMA (20)[1];
Def T101 = TEMA (10)[1];
Def Diff1 = T201-T101;
Def Diff = T20-T10;
Plot Scan = (Diff1 - Diff)/Diff1 > .4;

If I use the above scan, I don't get any results, but if I change the > to < I get results but, again, not the ones I'm looking for.

tema has 2 input parameters. the first is price, not length.
your formulas are evaluating tema of $10 and $20 , over and over and over.... not the stock price.

example formulas with 2 parameters,
Def T20 = TEMA(close, 20);
Def T10 = TEMA (close, 10);

try this code.
i made it a lower study, so i could see if there are output signals ( scan = 1)
i don't like putting constants in formulas, so i added input variables.

declare lower;
input tema_offset = 1;

input len1 = 10;
input len2 = 20;
Def T1 = TEMA(close, len1);
Def T2 = TEMA(close, len2);

def t1_off = t1[tema_offset];
def t2_off = t2[tema_offset];

def diff1 = t2_off - t1_off;
def diff = t2 - t1;

input ratio_level = 0.4;
Plot Scan = (Diff1 - Diff)/Diff1 > ratio_level;

Thank you Halcyonguy, it's exactly what I was looking for, I just didn't know how to input the right formulas. I appreciate the education.
