new to MQL4, are there any easier instructions/documentations? keep running in circles

New comment
 

Hi all,

I've just started to try and learny by myself mql4, however i'm finding it very difficult to understand the documentation that comes with it/provided in here.

I'm not a very technical person, and everytime I revert to the help/doc I find a simple matter explained in an even more technical way... 

I've only been to it for a couple of weeks so i'm not expecting miracles. So far i'm capable of coding basic stuff like printing out prices and indicator values.

Today i've been trying to draw some horizontal/vertical lines on the chart but i'm completely lost in the help.

I've figured out that I need to use the ObjectCreate function, but I'm lost in the parameters section.

For example help states something like :

chart_id

[in]  Chart identifier.


what does that mean? where can i find more info about it? what should it right in it? i know it has got nothing to do with the currenncy pair since I've come across that as chart smybol.

After some searching i've across yet another help page of chart id stating this

Returns the ID of the current chart.

long  ChartID();

Return Value

Value of long type.

This is what I mean, wasn't much help either.


So my question is, how can I go about finding my way out in knowing what all of this stuff mean and how to properly code/use it?

thanks in advance for any help

and sorry if this might sound stupid for the more experienced ones

short ushort int uint long ulong Since the unsigned integer types are not designed for storing negative values, the attempt to set a negative value can lead to unexpected consequences. Such a simple script will lead to an infinite loop:

Perhaps you should read the manual.

         RTFM and STFW: How To Tell You've Seriously Screwed Up.

You were at MQL4 Reference → Chart Operations → ChartID. If you had gone over to ChartNext, you would know how IDs work by looking at the example.

Unless you are trying to do something with multiple charts, you don't need to be concerned with them. You mentioned ObjectCreate, the second version doesn't require one.
