can you help me guys to code. I need 2 arrows when candles crosses BB and CCI bigger/lower then -+150. First one arrow like alert, second arrow when the trend changes just saying make your call/put.
I want to have alert sound on both arrows.

I use TOS - BB (CLOSE, 0, 20, -3.0, 3.0, SIMPLE)
CCI (5, 150, -150)

Thanks a lot for you help!

I'm just a begginer guys, so sorry if i wrote something wrong.
I decided to add EMA exponential and to get arrows when it crosses BB upper or lower bands. But it doesn't work. I don't see any arrows. Can you help me where I made a mistake?

#####EMA###
input price = close;
input EMA_Length = 3;
input aaverageType = AverageType.EXPONENTIAL;
def EMA = ExpAverage(price, EMA_Length);
plot EEMA= price;
EEMA.SetDefaultColor(GetColor(1));

####BB####

input displace = 0;
input length = 20;
input Num_Dev_Dn = -2.0;
input Num_Dev_up = 2.0;
input averageType = AverageType.SIMPLE;

def sDev = StDev(data = price[-displace], length = length);

plot MidLine = MovingAverage(averageType, data = price[-displace], length = length);
plot LowerBand = MidLine + Num_Dev_Dn * sDev;
plot UpperBand = MidLine + Num_Dev_up * sDev;

LowerBand.SetDefaultColor(GetColor(0));
MidLine.SetDefaultColor(GetColor(1));
UpperBand.SetDefaultColor(GetColor(5));

######ARROWS######

plot crossing = LowerBand < EEMA and LowerBand >= EEMA;
crossing.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
plot ccrossing = UpperBand > EEMA and UpperBand <= EEMA;
ccrossing.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);

Thank you!

Have to tell it is when it crosses instead of > or <

I think there are several ways to write "crosses" in thinkscript, this is one:

plot crossing = crosses(LowerBand,EEMA) and LowerBand >= EEMA;
crossing.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
plot ccrossing = crosses(UpperBand,EEMA) and UpperBand <= EEMA;
ccrossing.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);

it's working perfect, exactly as I was planning.

The only problem is that I can't use it as I was expecting. Can't trust these signals. Some of them are not good for trade.
I need to find another solution. To be more accurate.
