  Hello guys!

  I need the probuilder codes of the EMA, WEIGHTED and WILDER averages.

  Does anybody knows them?

  Thanks in advance

  Max

  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:

  EMA

  once customema=close EMALength = 10 alpha = 2/(EMALength+1) if barindex>EMALength then CustomEMA = alpha*Close + (1-alpha)*CustomEMA[1] endif return customEMA

  1 2 3 4 5 6 7 8

  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

  //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)

  1 2 3 4 5 6 7 8

  //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:

  WMA

  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"

  1 2 3 4 5 6 7 8 9 10 11 12 13 14

  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)

  1	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

  1	once wilder = close
