How to remove the error from Pinescript code

Question

I need some help. TIME FRAME = 5 mins. I want an indicator to plot the open and high till the first opposite color candle. Basically:

First candle positive and second candle negative, then plot high and low for the first 10 mins (price range of first two candles).

First candle positive and second candle positive and third candle negative, then plot high and low for the first 15 mins (price range of first two candles).

First candle is positive and second candle positive and third candle positive and the fourth candle is negative, then plot high and low for the first 20 mins (price range of first 4 candles).

I am getting the error: Mismatched input 'if' expecting 'end of line without line continuation'

// Declare a variable to track if the first red candle has been found
first_red_candle = false
// Declare variables to store the high and low of the day after the first red candle
high_after_first_red = na
low_after_first_red = na
// Iterate through the candles
for i = 0 to bar_index
 // Check if the current candle is red
 if close[i] < open[i]
 // Check if this is the first red candle
 if not first_red_candle
 // Set the first red candle flag to true
 first_red_candle = true
 // Otherwise, update the high and low of the day after the first red candle
 else
 high_after_first_red := max(high_after_first_red, high[i])
 low_after_first_red := min(low_after_first_red, low[i])
// Plot the high and low of the day after the first red candle
plot(high_after_first_red)
plot(low_after_first_red)

• vitruvius: This is chatGPT generated, isn't it?
• Jitesh Yadav: @vitruvius yes have been working on this indicator since the last 7 days but to no avail. So I tried this as well

Answer 1

The indentation in your actual code is made of 2 spaces, instead you must use a TAB indentation.
I tested your code with tabulation indentation and no errors.

• Jitesh Yadav: Thank you for your response. However, I am still getting errors. Would you be kind enough to paste the code after making the required changes? Would really help!

Answer 2

//@version=5 
indicator("Script") 
bar_index=1000
bool first_red_candle = false 
float high_after_first_red = 1
float low_after_first_red = 1
for i = 0 to bar_index
 bool cond = ((close[i] < open[i]) and not first_red_candle)
 if not cond
 high_after_first_red := math.max(high_after_first_red, high[i])
 low_after_first_red := math.min(low_after_first_red, low[i]) 
 else
 first_red_candle := not first_red_candle 
 
c_1 = high_after_first_red ? color.red : low_after_first_red ? color.gray : color.red
c_2 = low_after_first_red ? color.red : high_after_first_red ? color.green : color.red
plot(high_after_first_red, style=plot.style_line, linewidth=2, color=c_1) 
plot(low_after_first_red, style=plot.style_line, linewidth=2, color=c_2)

• Jitesh Yadav: thank you for your response. However, the high is changing as new high are formed throughout the day. I want to plot just the first high after the first red candle.
