why would Stochastic RSi on Open prices repaint current 0 bar.??..

[vvv23]

HI

 

why would RSi on Open prices repaint current 0 bar... I ve been on this for a coupel of weeks now and it's just getting me gray hairs..

 

Here is the code for RSI . why would it repaint current bar???? :)

 

I use it in the stochastic RSi that has the code below it as well. the stochastic RSI repaints as well..

 

I am especially interested in knowing why would the stoch rsi repaints since it is based on the RSI. the Stoch rsi is the second code below. thanks

 

there are 2 codes here. the first RSi the second Stoch RSI. thanks

 

Why? Anybody?

THANKS FOR YOUR RESPONSE.but if you look i am using Open_Price not Price_Close, so it should not repaint at all since there is only 1 open price per bar

anyone else?
