Full candle outside of Bollinger Band

[kabira]

Hello All - I am using the following script and its giving me the close of the candle outside of the BB. How can I adjust it to get the full candle outside of BB.

close from 1 bars ago crosses above BollingerBands("average type" = "WEIGHTED")."UpperBand" from 1 bars ago

couldn't you just change it from close to low for upper band, or high for lower band?

Edit: sry nvm that might not work after re reading

Edit 2: I just tested this by modifying tos's built in BBCrossover study and it does work

here is the code I tested:

input length = 20;
input Std_Deviation = 2.0;
input crossingType = {default above, below};
input averageType = AverageType.SIMPLE;


def bollingerHigh = BollingerBands(length = length, Num_Dev_Dn = -Std_Deviation, Num_Dev_up = Std_Deviation, averageType = averageType).UpperBand;

def bollingerLow = BollingerBands(length = length, Num_Dev_Dn = -Std_Deviation, Num_Dev_up = Std_Deviation, averageType = averageType).LowerBand;

plot signalHigh = Crosses(low, bollingerHigh, crossingType == CrossingType.above);
signalHigh.DefineColor("Above", GetColor(1));
signalHigh.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);

plot signalLow = Crosses(high, bollingerLow, crossingType == CrossingType.below);
signalLow.DefineColor("Below", GetColor(2));
signalLow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);

Thank you. Let me try. Appreciate it.

It worked perfect. Thank you so much.

Also similar type how can we get the same full candle outside of moving average 5EMA. (away from 5EMA) full candle outside not attaching to the EMA.
Thanks again.

NP, it was actually my first post on this forum so glad it was helpful.

the logic for your next question is the same as the first one, but I realized there was a slight error in my last script. If more than one candle in a row is outside the bollinger band only the first will be marked. you can change the last two statements to this if you want to fix it

plot signalHigh = low > bollingerHigh;
signalHigh.DefineColor("Above", GetColor(1));
signalHigh.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);

plot signalLow = high < bollingerLow;
signalLow.DefineColor("Below", GetColor(2));
signalLow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);

here is an ema script, I changed the candle colors instead of plotting arrows this time. if you want arrows instead remove the last line and add the two statements from above and change bollingerHigh/bollingerLow to ema

input length = 5;

plot ema = ExpAverage(close, length);

AssignPriceColor(if low > ema then getColor(6) else if high < ema then getColor(5) else getColor(7));

Thank you so much again. Yes I saw that If more than one candle in a row is outside the bollinger band only the first will be marked. Thanks for fixing it . Also let me try the 5ema one.

Hello Babel - It worked. Thanks. Below is my BB startegy is there a way we can get alert on this.

Bollinger band with standard deviation = 1.5

when a candle is completely above the upper Bollinger band , that candle will be called a signal/alert candle.
Initiate a Sell trade when that alert candles low is broken.

when a candle is completely below the lower Bollinger band , that candle will be called a signal/alert candle.
Initiate a Buy trade when that alert candles high is broken.

Also how can I put the alert on the below

input length = 5;

plot ema = ExpAverage(close, length);

AssignPriceColor(if low > ema then getColor(6) else if high < ema then getColor(5) else getColor(7));

when a candle is completely above the ema5 , that candle will be called a signal/alert candle.
Initiate an alert when that alert candles low is broken.

when a candle is completely below the lower ema5 , that candle will be called a signal/alert candle.
Initiate an alert when that alert candles high is broken.
