From SMA or EMA to f(x)

[[Deleted]]

Hi there!, 

Is there an existing way to convert the signal of a simple or exponential moving average to a math function of one variable?

Thank you very much in advance

Which variable ? Why do that ?

That would be very versatile. Many things could be simplified, I think, for example, the power of a trend would be the slope of the function at a given point.

Interesting dream ;-) But if anyone have this, I don't believe they share here.

Or we can fulfill this idea in an alternative way. 

Computing the tag() of two bars' MA,

eg: 

tag(A) = (SMA(1)-SMA(2))/ B

I know indicator sma different than ema. But i do not understand meaning sma,ema and application of them.

it return to the weight of the new and old data for calculate " average".

in ema the new data or " bar" has bigger weight .

Thanks for your reply, now I see this is a bit more complicated that I originally thought, but still interesting anyway.

thanks for clearly explain . i understand but i do not know use sma ema in my chart to trade

You have to learn from here

Hello there!,

Well, in fact I've discovered that it is not a dream! You can obtain a math function of one variable through Lagrange Interpolating Polynomials, for instance, cause there are several ways, but this is a hard work that should be explained in an article, I think.

For those of you interested in this problem, please, have a look at this
