I'm a newbie programmer. I've programmed an EA that will work in the strategy tester and will pop up a buy or sell window live. The problem is that no trades show up on the chart or in the account. Any ideas on why this might be happening?

Thanks

Hi. Well, if there are not trades shown in your account, it is obviously a problem with the trading logic - ie. it could be anything!

Apart from the obvious and posting the code for someone to look at, you should get an idea from the 'Journal' window during backtests as to why it is not opening trades (error messages).

Hi,
how can I get calculatet data of an indicator into an EA?
I have build those indicators:
Discret Butterworth-Lowpass-Filter (1st order)
I think one problem is, that one indicator creates 3 datafields (3 lines in chart-window). I need the current data and the shifted (one bar) data, too.
The indicator is called: butterworth-ad, so I tried the following to call it in an EA:
ibutterworth-ad(......), but that doesn´t work

Can someone help me?

Hey Justize. If you are using a custom indicator you have to call it differently. try this:
iCustom(NULL,0,"butterworth-ad"......,0,0)
iCustom(NULL,0,"butterworth-ad"......,0,1)
The second one is for the previous bar. You can look up "iCustom" in the search box in your meta editor if you want to understand more about how to call custom made indicators in your EA. I hope that is what you were looking for.

this article is working to react users' commands
Get keyboard keys to MetaTrader! | www.metatrader.info

but if i press the key in other window, it still works, that makes some conflict, does anybody know how to make it filter other window's keyboard event?

i tried the following:
#include <WinUser32.mqh>

……

#import "user32.dll"
bool GetAsyncKeyState(int nVirtKey);
int GetForegroundWindow();
#import

……

int start()
{
string lpString1;
int nMaxCount1;
int hwa= GetForegroundWindow(); //this api works
nMaxCount1 = GetWindowTextLengthA(hwa); //this api works
int x = GetWindowTextA(hwa,lpString1,nMaxCount1); //it returns 0, lpString1 is null too here
if ( GetAsyncKeyState(VK_0))
Alert("0 pressed "+hwa+" "+nMaxCount1+" "+x+" "+lpString1);

}

Hi,
thank you very much, that i, what i need!

You're welcome.

Dear Friends,

I need some help.

Can somebody create custom indicator as follows :

Line 1a
Price Open - (Previous Range / 5)

Line 1b
Price Open - (Previous Range / 2)

Line 2a
Price Open + (Previous Range / 5)

Line 2b
Price Open + (Previous Range / 2)


The line can changed automatic for all time frame, its mean can automatic change with each period (M30, H1 or H4).

Thank you for your help.

Kind Regards,
Herly

What is the code for this?

if Bid was(not is)greater or equal to 1.3450, then.........???


Thanks all!

If by "was(not is)" you mean during the previous bar then you can use:
iHigh(NULL,0,1) to return the highest bid price of the previous bar to see if the Bid "was" greater than X price. If you want to see if a bid during the current bar but not the current price was greater than X price that can also be done but is a little more tricky but easy enough. PM if you need more help.
