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

New comment
 

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

Why? Anybody?
