DEMA EMA and SMA

[xxentre]

Can someone put something like this together?
I have no Idea where to begin. It looks like it could be useful. Let me know of any thought on this. I barely understand it. I just thought I would share if it worth it.
All the same of Period 7-20
15 cross 50
20 DEMA = (2*EMA9( n ))-(EMA( n ) of EMA( n )))
EMA
SMA

here is the basic dema formula

# dema
# DEMA = (2*EMA( n )) - (EMA( n ) of EMA( n )))

def price = close;
input length = 10;

# calc an ema
ema1 = ExpAverage(price, length);

# calc an ema of an ema
emaema = ExpAverage(ema1, length);

plot dema = (2 * ema) - emaema;
dema.setdefaultcolor(color.yellow);
#

i don't know what you mean by 15 cross 50? 15 what cross 50 what? cross up, cross down , either.

I don't know why you have an EMA9 in the formula?

20dema ? Variable names can't start with a number. DEMA20 would be a valid name.

The formula came from the video and the 9 was in the formula. I was unclear from the video as to what he was explaining.
