RSI Highs Lows

[shakib3585]

Hello All,

I am looking for RSI script.
Using the ToS RSI calculation: RSI()
Adding a blue dot for new RSI highs and red dots for new RSI lows, within a given period.

For example,
if I choose my period to be 21,

• each time the RSI makes a high considering the last 21 bars, it will show a blue dot on the RSI line.
• The same is true for RSI making a new low considering the previous 21 bars; at that instant, a red dot would appear on the RSI line.

if I choose my period to be 52,

• blue dot for new 52-bar RSI highs
• red dots for new 52-bar RSI lows.

Also: the line should be green while increasing and red while decreasing
By increasing, I meant if the current RSI value is higher than the previous one and vice versa. Thank you so much!

Please help.

Thank you very much!

i changed the bottom dot color to be magenta, so it would stand out more.

Thank you so much @halcyonguy

Thank you so much @halcyonguy

Hey @halcyonguy, I was researching RDDT stock using the RSI developed by TOS and the one developed by you. The aggregation period is a Week. I noticed the beginning portion of the RSI is missing on your chart. I have attached the picture for reference. Can you please help me to resolve it?

pick almost any other stock and it works. RDDT only has data from 3/21, so not enough data.
when i change these, it draws a short line
input rsi_length = 8;
input past_bars = 6;
