Hi guys. Will someone please assist with the indicator code attached.

So I have converted the mt4 code to mt5 with the help of Chatqbt and the signal arrow appears in mt5 like it does in mt4 but It seems like it does not want to refresh the arrow in mt5.... even if I have a auto refresh ex5 file loaded on chart, it refreshes when I change between timeframes but in mt4 it does not need to refresh to display. The indicator does repaint but very little.

Your help will be greatly appreciated.
