Have you used this function? Can you show me the code or how you would do it, because I think I'm getting stupid in the easiest place

No, I don't. In any case, the error is not in the function, but before it.

There was also an error:

't' - variable not defined, so it's a variable. I can't figure out what to do with it.

Hi all! Please help me combine the following things. The result should be: two lines following the price, one lower than Ask by 20 pips..,

the other one is higher. Besides, I get a beep if price changes by 20 points per 1 tick.

All works fine separately. Thanks in advance!

1) The line below the Ask by 20 pips.

//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int start()
{
ObjectCreate("MyPriceLine", OBJ_HLINE, 0, 0, Ask-20*Point) ;
ObjectSet("MyPriceLine", OBJPROP_PRICE1, Ask-20*Point);
return(0);
}

//+------------------------------------------------------------------+

2) The line is 20 pips above the Ask.

//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int start()
{
ObjectCreate("MyPriceLine", OBJ_HLINE, 0, 0, Ask+20*Point) ;
ObjectSet("MyPriceLine", OBJPROP_PRICE1, Ask+20*Point);
return(0);
}

//+------------------------------------------------------------------+

3) Rate of price change over time.

There was also an error:

't' - variable not defined, so it's a variable. I don't know what to do with it.

This is an afterthought...

If it wasn't for the first error `(`), we would have thought about what was wrong. But with this first one, everything is clear.

 
I think it's the same, just highlighted in colour and that's it
 
DhP:

This is already as a consequence...

If it wasn't for the first error `(`, you might have wondered what was wrong. And with this first one, everything is clear.


Thanks, I'll keep looking.

It's the same, but it's easier (more familiar) to read the code.

I'm too lazy to figure it out, but someone will easily find a mistake in your code without straining. Just wait.
