why i have this error ???

hi everybody,

on tradingview , pinescript find an error in my code :

// Define the MACD function
macd(src, fast_length, slow_length, signal_length) =>
fast_ma = sma(src, fast_length)
slow_ma = sma(src, slow_length)
macd_line = fast_ma - slow_ma
signal_line = sma(macd_line, signal_length)
histogram = macd_line - signal_line
return[macd_line, signal_line, histogram]

In the last line the first ' , ' have a red underline ......

someone can find a solution ?

thanks

Hi

remove the return keyword, it's not a pine keyword

[macd_line, signal_line, histogram] is enough

tks dave dave

i also have a wierd error.. - Could not find function or function reference ta.ema

this is the code

//@version 5
strategy(20 EMA & 50 EMA Crossover with Stochastic RSI Filter)

length = input(title=Length of EMAs, type=integer, defval=20)
oversold = input(title=Oversold level, type=integer, defval=20)
overbought = input(title=Overbought level, type=integer, defval=80)

// calculate the exponential moving averages
ema20 = ta.ema(close, 20)
ema50 = ta.ema(close, 50)

// calculate the stochastic RSI
rsi = ta.rsi(close, 14)
k = ta.stoch(rsi, 3)
d = ta.sma(k, 3)

// long entry conditions
long_entry = crossover(ema20, ema50) and crossunder(k, oversold)

// long exit conditions
long_exit = crossabove(k, overbought)

// short entry conditions
short_entry = crossunder(ema20, ema50) and crossabove(k, overbought)

// short exit conditions
short_exit = crossunder(k, oversold)

// plot the long entry and exit signals
plot(long_entry ? close : na, title=Long Entry, style=plot.style_circles, color=color.green, linewidth=3)

// create overlay to display on the chart

Hello helper,

I'm getting error Incorrect 'for' statement. Expecting 'to '. for the below pine code. Can anyone please help?

indicator(My Script, overlay=true)

// Define the colors for the candles
yellow = #FFFF00
white = #FFFFFF
orange = #FFA500
silver = #C0C0C0

// Initialize variables to keep track of the state
entryLong = false
exitLong = false
entryShort = false
exitShort = false

// Use the bar_index function to go through each bar on the chart
for i = 0 to bar_index

// Check the entry long condition
if (high[i] > high[i+1]) and (low[i] > low[i+1]) and (close[i] > high[i+1])
entryLong := true
exitLong := false
barcolor(yellow)

// Check the exit long condition
if (entryLong) and (high[i] < high[i+1]) and (close[i] < low[i+1])
entryLong := false
exitLong := true
barcolor(white)

// Color the candles yellow between entry long and exit long candles
if (entryLong) and not (exitLong)
barcolor(yellow)

// Check the entry short condition

First !!! You didn't used Pine //@version=5
You wrote //@version 5 ... for this reason the Pine Editor thought you are creating Code for Pine //@version=1

The right instruction for unsing PineScript Version 5 --> // @version=5

Sorry for double Entry's, couldn't find a way how to delete a message.

Hello ,
There are some issues with your code. I'm not a expert, but maybe this helps you.
I didn't correct your formula ... only where are some obvious problems with the code.
IF you use the Errormessages in the Pine-Editor window ( bellow) .. then you will see where the problem is.

When you decleare a veriable with a input then you need to say witch variable should be created with this Input ... so right is .. length = input.int (title=Length of EMAs, defval20) ...
you neet the quotes, this was several times not used in Methods of you.
There was several other issues with the Namespace where you not said to the system where he should take the funktion ... ta.crossover ... crossover allone not working ... then you used crossabove .. this is not a existing method.

You will find the full help in the Reference Manual for Pinescript on Tradingview.

Jignesh P (@jigneshp):
The bar_index ist the actual bar ... and 0 is also the actual bar ...
So
For I=0 to 0 ...
maybe you wanted do something else ...
