Code to plot CURRENT signal only

[David45]

Is there a universal code that can be applied to any indicator so that it only plots the current signal/arrow and no historical signals/arrows? Or would the code need to be specific to the indicator? Below is the potion of code I am trying to alter so that it only plots the current signal/arrow but nothing I've tried has worked. I'm just wondering if I am overthinking this and there is a simple way to do this that I am unaware of. Thank you for any insights and assistance!

# calculates and plots the arrows
def EIL = if !IsNaN(EI) and !isUp then pricel else GetValue(EIL, 1);
def EIH = if !IsNaN(EI) and isUp then priceh else GetValue(EIH, 1);
def dir = CompoundValue(1, if EIL != EIL[1] or pricel == EIL[1] and pricel == EISave then 1 else if EIH != EIH[1] or priceh == EIH[1] and priceh == EISave then -1 else dir[1], 0);
def signal = CompoundValue(1, if dir > 0 and pricel > EIL then if signal[1] <= 0 then 1 else signal[1] else if dir < 0 and priceh < EIH then if signal[1] >= 0 then -1 else signal[1] else signal[1], 0);
def showarrows = yes;
plot U1 = showarrows and signal > 0 and signal[1] <= 0;
U1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
U1.SetDefaultColor(Color.GREEN);
U1.SetLineWeight(4);
plot D1 = showarrows and signal < 0 and signal[1] >= 0;
D1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
D1.SetDefaultColor(Color.RED);
D1.SetLineWeight(4);

Figured it out! I used some code that SleepyZ helped me with for another indicator and it worked on this one too! So Kudos to SleepyZ!

input Count = 1;
def cond = if signal > 0 and signal[1] <= 0 or
signal < 0 and signal[1] >= 0
then 1
else 0 ;
def dataCount = CompoundValue(1, if cond then dataCount[1] + 1 else dataCount[1], 0);
def limitplot = HighestAll(dataCount) - dataCount <= Count - 1;
#-------------------------------------------------------------------------------

input showarrows = yes;
plot U1 = showarrows and signal > 0 and signal[1] <= 0 and limitplot;
U1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
U1.SetDefaultColor(Color.GREEN);
U1.SetLineWeight(4);
plot D1 = showarrows and signal < 0 and signal[1] >= 0 and limitplot;
D1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
D1.SetDefaultColor(Color.RED);
D1.SetLineWeight(4);
