Average

How do you write a screener where you want Demarker Indicator period 3 to cross over Exponential Moving Average period 3 ?

Thank you in advance.

Hi @Mary

DeMarker is an indicator with a ratio between 0 and 100 (equal to the RSI).

EMA is an indicator with a value based on price.

So, you can’t compare the two… (DeMarker can’t cross over an EMA)

Or do I misunderstand your question?

Average

So I have this Demarker Indicator on my chart (please see code below) and I added an Exponential Moving Average period (3) to it so it crosses over( see pic below). I just don’t know how to write a screener for it. //DeMarker Indicator period=3 up=max(0,high-high[1]) down=max(0,low[1]-low) ratio=100*average[period](up)/(average[period](up)+average[period](down)) return ratio as “DeMarker”,20,80

Hi @Mary

Okay, I understand now…

The screener can look like this…
```
//DeMarker + EMA Screener

period=3
up=max(0,high-high[1])
down=max(0,low[1]-low)

ratio=100*average[period](up)/(average[period](up)+average[period](down))
xEMA = ExponentialAverage[period](Ratio)

If ratio Crosses Over xEMA then
Signal = 1
Else
Signal = 2
EndIf

SCREENER[Signal](Signal AS "1=long, 2=short")
```
