This kind of code should be close enough to a real daily EMA, but in intraday timeframes:
```
p=14 // periods

once dailyEMA = DClose(0)

if intradaybarindex=0 then
oldEMA=dailyEMA
endif

k = 2/(p + 1)

dailyEMA = Dclose(0)*k+oldEMA*(1-k)

RETURN dailyEMA
```

Thanks Nicolas. Based on EMA formula (http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:moving_averages) and my initial request:

EMA(3) is what gets calculated. In you example code it is EMA(14). But what I need is to convert below pinescript:

//@version=3
study(“My Script”)
m=security(tickerid, “8D”, ema(close,3))
plot(m)

also, once this is works I need to convert this as a screener. Currently Tradingview lacks in this. TOS doesn’t have 8D but they do have 1d, 2d, 3d and 4day period but NOT 8D :(.

So to be clear, you want to get the EMA 3 periods of an 8 days timeframe?

Yes, Nicolas but plot it on a Daily chart view.

If you run that script I shared on Tradingview you will see what I mean.

Finally, I need to convert it as sceener.

Thanks

Just a quick and rough code this morning (have to go), please have in mind that there is no multi timeframe support in ProBuilder.
```
p=3 // periods

once dailyEMA = DClose(0)

if barindex<>oldBAR and barindex>0 then
oldEMA=dailyEMA[1]
oldBAR=barindex
count=count+1
if count=8 then 
count=0
price=Dclose(0)
endif
endif

k = 2/(p + 1)

dailyEMA = price*k+oldEMA*(1-k)

RETURN dailyEMA
```
About the screener, please give me at least one condition to fire alerts! Thank you.

Thanks Nicolas ..this gave me the idea … here’s the code but i’m not getting the quite the value it should be for 8D ema(3).
```
once count = 0

if count = 7 then

p=3 // periods
 
once dailyEMA = DClose(7)
 
if intradaybarindex=0 then
oldEMA=dailyEMA
endif
 
k = 2/(p + 1)
 
dailyEMA = (Dclose(7)-oldEMA)*k+oldEMA

count = 0
endif

count = count + 1

RETURN dailyEMA
```
within “if count” structure and having dclose(0) will get EMA(3) so Dclose(7) will get me close of 8th day. Previous ema calculation is what i think needs to be fixed to get my code working 100% accurately.
