'OnInit' - unexpected token

This is my first time coding in MQL4

I’m not sure what the error is, I was following a video of youtube, and it seems my code has multiple errors even though it was the same, could this be because it was an old video and mql4 language updated?

Here is the code below

These are the current errors, I did have more but after some searching I found some fixes, not sure if it is correct though

Thank you, seems to have fixed two of the initial four errors, makes it a bit easier :slight_smile:

this is not a valid directive/syntax:

if(ticksize == 0.00001 || ticksize == 0.001); // if- statements must have some body but you're ending the statment with the ';'
// this is the 'unexpected token'
