Hi, I'd be grateful if someone can help me transform the following study i found in this forum edited by BonBon with a customized HA indicator to a scanner.

#Signals1
#Original code by Taz43
#updated by BonBon 1/15/21 inccreased swing_back periods, changed "high and Low to Halow1 and Hahigh1".

def sb = swing_back;
def sf = swing_forward;
def na = Double.NaN;
def lfor1 = Lowest(halow, sf)[-sf]; #Remember that a negative number inside the square brackets means "after" this bar. So, the above line is defining "lfor" as being the lowest value of the two bars after this bar.
def lback1 = Lowest(halow, sb)[1]; #This line of code is defining "lback" as the lowest value of the eight bars before this one.
def swinglow1 = if halow < lfor1 and halow < lback1 then 1 else 0;
#Finally, this line is actually defining what a "swing low" is. It says, if the low of this bar is lower than the two bars after this one AND the low of this bar is also lower than or equal to the lowest of the previous eight bars, then this bar is a swing low. So, what that means is that in order to determine whether a point on the chart is either a swing high or a swing low, it must have eight bars before the bar in question, as well as, two bars after it. Looking at the picture above, it can be seen that point "A" is a "swing high" because it is higher than the 8 bars before it AND it is higher than the 2 bars after it. Likewise, point "C" is a "swing low" because it is lower than the 8 bars before it AND it is lower than the 2 bars after it. (I know it's a line chart, not a bar chart. smiling smiley Just work with me here.)
def hfor1 = Highest(hahigh, sf)[-sf];
def hback1 = Highest(hahigh, sb)[1];
def swinghigh1 = if hahigh > hfor1  and hahigh > hback1 then 1 else 0;

plot fh = if swinghigh1 then hahigh else na ;
fh.SetDefaultColor(Color.red);
fh.SetPaintingStrategy(PaintingStrategy.booleaN_ARROW_DOWN);
fh.SetLineWeight(1);

plot fl = if swinglow1 then halow else na;
fl.SetPaintingStrategy(PaintingStrategy.boolean_ARROW_UP);
fl.SetDefaultColor(Color.green);
fl.SetLineWeight(1);
