Offline Chart Expert Advisor
Hello,
i created an Expert Advisor for an offline chart that looks like the following code:
int init()
{
start();
return(0);
}
int start()
{
while (!IsStopped())
{
RefreshRates();
//execution code
Sleep(1000);
//print each 5 mins a message "i am alive"
}
}
After some minutes the message "i am alive" was stopped.
Is there is something i can do about it or as i read in some other topics, it is a problem of every offline chart EA?
Thank you very much

Use information from M15 to enter or exit trade on M5
I want to calculate MA or other technical indicator on higher time frame to make decision to enter or exit trade in lower time frame. I do not want to specify period in indicator. I try to use PERIOD_M15 or other but the value not correct when compare to the real one.
...
If you use it like this :
[/PHP]
it has to return the correct value. Here is an example of a 15 minute 14 period EMA of close of the first closed bar
If you want to use that from back-tests then you have to add one thing :
[PHP] y = iBarShift(NULL,PERIOD_M15,Time[shift]);
iMA(NULL,PERIOD_M15,14,0,MODE_EMA,PRICE_CLOSE,y+1);
where shift is the number of the bar of the time frame you are testing

Thank you mladen, I am not sure it's must get the correct value or not.

How to prevent EA from working during MT4 startup
Hi Mladen,
A few days ago after rebooting my VPS, I restarted MT4. However, an EA on the platform accidentally closed some trades that should not have been closed, due to unstable data during MT4 start up. Can you please suggest some codes that I can insert in my EA to prevent this from happening ?
Thanks in advance

First that comes into mind is to prevent it from working on a first tick it receives
That could be done if you place something like this at the beginning of the start
But I am not 100% sure that it will prevent all errors like the one you had (when it starts to download data for example that can get lengthy - what to do then). If I come up with a better idea will post it here
