Proprietary software is usually undisclosed, you may try to apply PRT but I don’t think you’ll get any useful help (it would be odd if they did!).

You may search this forum for versions that you may modify to suit your needs.

You may also search the web for the formulas and build them on your own.

Hi Roberto, yes I know probuilder indicators codes are not available, actually I was asking if anyone has programmed on it’s own the codes of the 3 averages to be able to modify them.

Overall to use them as daily filter on the intraday timeframes.

Exponential moving average code:
```
once customema=close
EMALength = 10
alpha = 2/(EMALength+1)
if barindex>EMALength then 
 CustomEMA = alpha*Close + (1-alpha)*CustomEMA[1]
endif

return customEMA
```

Wilder Moving Average code:
```
//Wilder MA
N = 10
K = 1/N
if barindex>N then
 wilder = close * K + wilder[1] * (1-K)
endif

return wilder coloured(255,0,0)
```

Thanks so much Nicolas!

Don’t you have also the weighted average?

I recoded them from scratch, don’t have time enough to code the last one yesterday. I’ll try to make it today.

Weighted Moving Average code:
```
period = 10
price = customclose

pricesum=0
a=0
for i = 0 to period do
 p=period-i 
 pricesum = pricesum+price[i]*p
 a = a + i
next 

wma = pricesum/a

return wma as "wma"
```
All is good now 🙂

Hello Nicolas 🙂 Thanks for the codes ! It’s really useful

I’m wondering something about the wilder moving average code, on this line:
```
wilder = close * K + wilder[1] * (1-K)
```
I understand it’s a sophisticated way to make a loop,

at the first iteration of the loop, i guess wilder is undefined, so “wilder[1] * (1-K)” should equals to “undefined * (1-K)”

so my guess is that it is equal to 0 on the first iteration

am I right ?

Indeed, so you can add this line at the top of the code in order to get a value for the first iteration of the loop:
```
once wilder = close
```
