Crossover screeners with price and volume filters

Hi All,

Apologies if this question has been covered previously, I am a complete noob when it comes to coding screeners.

Firstly I have amended one of the built in crossover screeners to fit the criteria I am looking for. It works great. However I am looking to add two additional criteria. I would like to add a price range, for instance all opportunities with price below X, or between X & Y. I have tried a few things and cant work it out.

It would also be helpful to add a volume criteria, so all shares with a trading volume of +x.

The code I have so far is below any help would be greatly appreciated.

REM Calculate a simple moving average over the last 5 days

ema5 = ExponentialAverage[5](close)

REM Calculate a simple moving average over the last 21 days

ema21 = ExponentialAverage[21](close)

REM Calculate the differential speed between the short and the long moving average

speed = MOMENTUM(ema21-ema5) * 100 / CLOSE

REM Display securities for which short MA has just crossed over long MA.  Show the fastest crossings first.

IF ema5 CROSSES OVER ema21 THEN

SCREENER (speed AS “Speed”)

ENDIF

I am also trying to set up a screener to identify crossovers where the ema 21 crosses the SMA 400. I have recently been informed that I can’t screen for any averages over 250? Is this correct? If so is there any other way to identify these cross overs?

Best regards,

Andrew
