I appreciate your help. As I remember, To get indicator's value,It doesnot need to declare the handle at onit() in MT4?
So why does mt5 has to?
hello, I am trying to create an expert advisor based on ichimoku. my code worked when i only used tenkansen and kijunsen, but since adding the chikouspan, SSA and SSB it doesn't work anymore, i really need help, thanks. here is my code:

Hi,experts
I doubt if we can change parameters of indicator during the ea/script is running?
as we know,we need to declare (ma_Period,symbol) them in Onit() firstly before using.
Let say I want to use moving average’value of 10-50 period,Does I need to declare 40 buffers and 40 handles?
thank you very much
