Adjusting an EA from 4 digit to 5 digit broker

I trade an EA on IBFX. I know when going from 4 to 5 digits I need to add a 0 to TP,SL and pip step. My question is if I'm trading .02 lots, do I need to change that to .2? If my slippage is set to 10, should I change that to 100? And finally, when I click on File then Compile, I'm then unable to attach the EA ( with changes ) to the chart. thank you
I made a posting on my blog that may be of use to you.

In short; no, yes and not sure why that would be - any errors being reported?

This could be a bit late to get a reply luxinterior but to get my 4 digit code to work can I just add a 'Zero' to all my pre-sets at the top of the EA's code to catter for the 5th digit.
Example. extern int Slippage = 2; .....change the 2 to 20....and just do the same to T/P, S/L etc.

Or (apart from custom indicators/scripts) are there other factors that need to be addressed that would be covered by your example.

Thanks.
Is it possible that someone could post the code and/or rules when trying to convert a typical 4 digit EA to a 5 digit EA. I'm having a little trouble with the process and want to get it right.
Super Easy. Put this at the top of your code - right after start() - (I usually make xecn a global variable so I can use it anywhere. Also ECN were the first to have 5 digits so thats where the name came from)

xecn=1; if(Digits==5||Digits==3){xecn=10;}

Now just anywhere in the code where you see:

...*Point change to *Point*xecn - and all will be handled automatically.
Thanks Aja,

I'm gonna try it out in a few. I'll let you know how I fair.

Hey Aja,

I just tried what you suggested, to no avail though. I'm trying to get the EA to run on FXDDs Metatreder4. Here the error I got when trying to complile:

"'xecn' - expression on global scope not allowed"

&

"'xecn' - variable not defined"

I'm assuming that it's something I'm doing wrong. I know nothing about this stuff and sorry for seeming so dumb when it comes to it. LOL I just saved it after changing all the *Points to *Point*xecn as you mentioned. I've included an attachment of the script that I'm trying to get to work if you want to refer to it.

I’ve been able to add the EA to my indicator to my expert advisers as I would any other but for one reason or another it fails to load and operate. After trying to add the the EA to my chart or trade by double clicking it I get no response so I’m assuming that there is something slight in the EA that’s not allowing it to function.

Any other suggesting or can you tell me what I'm doing wrong?

Sorry I forgot to add the attachment. It's with this post.

You didnt define the variable type - just put 'double' in front of it. (I usually define as a global but locals work just as good)

double xecn=1; if(Digits==5||Digits==3){xecn=10;}

Also scanned your code and wherever ... /Point also change to /Point/xecn.... (in code i saw /Point/10 = /Point/xecn/10)
Aja,

I can't thank you enough for getting me thus far and I did get rid of some of the errors after modifying those other 'Point' entries.

I apologize for being totally ignorant to the things you are pointing out but I'm still having one error when attempting compile. You can see it here:

'{' - expression on global scope not allowed C/documents and Settings4592DesktopPowerSM2.mq4 (43, 1)

So apparently there's one other thing I'm doing wrong. Please help me out if you still have the patience to do so.

Again I've attached the EA. This time I didn't attach it in it's raw form but with the provisions you directed me to input. This way you can see exactly where I have anything.

Thanks again!

int init();double xecn=1; if(Digits==5||Digits==3){xecn=10;} - ERROR

move the line and place after the start() like this..

void start() { double xecn=1; if(Digits==5||Digits==3){xecn=10;}

In the error example you put it in the init() AND placed it before the '{'
Aja,

I did as you said once again. Changed lines and making sure it appears like so :void start() { double xecn=1; if(Digits==5||Digits==3){xecn=10;}.

I'm now getting the error that the variable can't be defined 16 times. I'm assuming that each time it comes up it's in reference to the appearance of Point in the code (I am learning, slowly but I didn't know that prior to this).

Again I've included a copy for your reference with the movement I made. Thanks again and wish I knew some info I could share with you to make up for all you're informing me with.

Here ya go. The variable needed to be defined as a global (meaning the entire program can access the variable not just routines in the start() function) - It now compiles without error.

Aja,

I didn't get a chance to offer you a thanks for guiding me through the process and showing me exactly how to get to the result I was in search for.

Thanks a million and you are absolutely the best. I'll keep you updated with how the EA goes for me via this thread.
