Hi, please find attached.

I have set the field “DayCount = 4” covering five days, change it to any number (e.g., changing it to 9 will give crossover in last 10 days).

Have fun …kaq52

//Author KAQ52
//This screener finds crossover of two averages in last n days

DayCount = 4  //change it as appropriate

REM Calculate a simple moving average over the last 50 days
ma50 = AVERAGE[50]
REM Calculate a simple moving average over the last 200 days
ma200 = AVERAGE[200] 
REM Calculate the speed at which the short MA crosses under the long MA
speed = MOMENTUM(ma50-ma200) * 100 / CLOSE


Crossover=0  //flag for detecting crossover


For i = 0 to daycount
if (ma50[i] crosses over ma200[i]) or (ma50[i] crosses under ma200[i]) then
CrossOver=1
break
endif
next


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

SCREENER [Crossover] (speed AS "Speed")

Thanks RobertGozi, your solution looks much precise.

My understanding so far is that “for i = 0 to daycount” with daycount=4 loop will get below five values, thus covering five days(including current one). Is this understanding not correct please?
