Need help to find highest value of an array...

How do i find the highest value of an array or how do i find the highest value in a +ve supertrend , i tried using HHV & highest function but counldn't get the signals that i wanted
so plz help me with this (plz see pic for clear understanding)

Can you explain the logic you are using to generate buy/sell signal. In your code buuy = supertrend<C; and seell = supertrend>C . In this the value of buuy and seell can only be 0 or 1. This you have followed up with Highest(buyy) which will always return 1 and hence latest() will also return 1.
hello jinujose , thanks for your reply

As I am new to coding I don’t understand how to build these logics,

The logic that I had pasted in query is not correct and this isn’t where my signals need to appear.

I want signals to appear when 1st candle of current +ve supertrend need to appear above high of prev +ve super trend high.

I wasn’t sure which function do I need to use( hhv or highest), if I need to used 1 of these do I need to plot lastvalue along with this or ??????(I am confused).

Plz see this pics you will understand the logic that I want

Thank you….
