Hi,

Step 1 – Store your moving average into a variable, for example named my myMA :

myMA =

Step 2 – Define from words to quantity what a « very tight range » means to you, and store it into a variable, for example named maxrange:

maxrange =

Step 3 – Define highest within x of your MA and lowest within x of your MA, and store in a true or false condition how further apart they are relatively to your maxrange :

MAHH=highest[x](myMA)
MALL=lowest[x](myMA)
condition = (MAHH-MALL)<=maxrange

And, because we are in the proscreener forum, and screeners have a more limited history than indicators and strategies, assuming you asked this to include within a screener, for this to work properly you would of course also need to ensure your moving average was already existing at the oldest of those x bars, that is to say the sum of [your moving average period] + [x] – 1 must be lower or equal to your max screener history (for example, moving average period 200, and x = 100, wouldn’t work for a 256 number of bars screener max history on prt complete, but would be ok for a 1024 max on prt premium)

Try this one:

ONCE X   = 0.05   //0.1% is the percentage wothin which  an MA is considered FLAT
ONCE N   = 20   //10 candles in a row is the requirement to tell an MA is FLAT
Sma1     = average[100,0](close)
Sma2     = average[N,0](Sma1)
SmaGap   = abs(Sma1 - Sma2) <= (Sma1 * X / 100)
BackgroundColor("White",255)
FlatLine = (summation[N](SmaGap) = N)
IF FlatLine THEN
   BackgroundColor("Green",50)
ENDIF
RETURN SMA1 AS "Sma1",SMA2 AS "Sma2"
