# scan for the (last) crossing in the last 20 bars

I tried to make a scan searching for the Moving average crossing in the last 78 bars but I end up searching for the longer than 20 bars no matter what coding I use .
Here is the code i used ;

input price = close;
input length1 = 55;
input length2 = 21;
def AverageType1 = averageType.SIMPLE;
def AverageType2 = averageType.HULL;
def avg1 = movingAverage(averageType1,price,length1);
def avg2 = movingAverage(averageType2,price,length2);
plot scan = (avg2 crosses above avg1 ) within 78 bars ;

sorry for my bad explaining above.
and thank you so much for your replay,

what i tried to do is building a lower indicator looking for "the most recent" crossing in the last x numbers of bar.

I've seen a code for you in another topic but that one is finding the crossing at “anytime" in the last X price candles link below:

i hope that I explained it clearly this time.

also i used the code you submitted above and didn't work, sorry.

thanks again, and your help means a lot to me.

no need for sorrys. i just state things as i see them.

don't say 'didn't work' it doesn't explain anything.

will try to...

i have no idea what your words mean, 78 , 20 , ...?

it looks like your code should work as a lower study, to be true on the last bar.

here is another version to try ( i tested this as a lower, i didn't test it as a scan, i don't scan)

Code:
``````declare lower;

def na = Double.NaN;
def bn = BarNumber();
def lastbar = !isnan(close[0]) and isnan(close[-1]);
def price = close;
input length1 = 55;
input length2 = 21;
input bars = 78;
def AverageType1 = averageType.SIMPLE;
def AverageType2 = averageType.HULL;
def avg1 = movingAverage(averageType1,price,length1);
def avg2 = movingAverage(averageType2,price,length2);
def x = (avg2 crosses above avg1);

def x2 = if lastbar and sum(x, bars) > 0 then 1 else 0;
plot z = x2;

# test data , each crossing
#plot y = (x * 0.5);
#``````

will try to make another version... typing on cell. .

Code:
``````declare lower;

def na = Double.NaN;
def bn = BarNumber();
def lastbar = !isnan(close[0]) and isnan(close[-1]);
def price = close;
input length1 = 55;
input length2 = 21;
input bars = 78;
def AverageType1 = averageType.SIMPLE;
def AverageType2 = averageType.HULL;
def avg1 = movingAverage(averageType1,price,length1);
def avg2 = movingAverage(averageType2,price,length2);
def x = (avg2 crosses above avg1);

def lastbn = highestall(if !isnan(close) then bn else 0);

def xbn = if x then bn else 0;
def x3 = if (highestall(xbn) == bn and bn >= (lastbn - bars) ) then 1 else 0;
plot z3 = x3;

#def x2 = if lastbar and sum(x, bars) > 0 then 1 else 0;
#plot z = x2;

# test data , each crossing
#plot y = (x * 0.5);

Thank you very much it worked perfectly.
