Plot Signal Once ATR Crossover

[grey]

here is the simple code that i wrote:

input length = 21;
input averageType = AverageType.WILDERS;

def ATR = MovingAverage(averageType, TrueRange(high-low, (high-close[1]), (low-close[1])), length);

def bull = movavgExponential(close,21) + atr;
def bear = movavgExponential(close,21) - atr;

plot bullcross = crosses(close,bull, crossingdirection.above);
bullcross.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);

plot bearcross = crosses(close,bear,crossingdirection.below);
bearcross.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);

To make the chart or signal clean, can someone help me plot the first crossover only? like the one encircled on the chart.

Thank you

Not sure what you are asking, but if you convert your study into a strategy, you will only have one bullcross until a bearcross occurs.
