In Pine Script, I want to write a code that first, detects low price of the look back period 200 candles, then adds a plus sign like the following picture. Thank you This is the picture
Armin,
Have a look at this post it might help or get you started with experimenting.
If you were to change circle to cross and only show the low and change the time period.
As you mention above 200 candle look back and the image you provided was 5 min TF so about 16ish hours data.
