a very simple program

Hi all!

I am just a newbie in mql language so please bear with me.
My program logic is very simple. Daily timeframe. Open both buy and sell orders at the opening price of the candle. only closes orders base on 2 criteria, 1. when TP reached 2. When SL reached and when TP is set to disable, closes the order when the closing price reached for the day.

So any volunteer writing the above simple program? thanks for the help!

Why not answers

I notice most seniors members are not answering ....... because the newbie questions are same and already answered so many times in these pages.
The newbie will not bother to read and explore all the forum they just need everything before "eye blink"
I red 100s of silly questions in forums which already answered
so please search your question i am sure there are 90% answers available of the questions which raises in newbies mind

einstr is on a distinguished road
order 0 failed to close. error: 4051

hello,

I have downloaded the divergence trader EA from the library and have been optimizing it and testing it in a demo acct for about three weeks. It appears to be working quite well but each time I switch to the live account, I get the error in the title in an alert window. I get this alert about every 20 seconds. It actually caused other orders that I had open at the time to close immediately upon the alert.

Could you please help me to find out what the issue is?

Thanks.
Rich

Order book data

Hi,

I am very new in MetaTrader, but very interested if I can use order book data in my codes. If yes it would be great a simple sample code (or at least some keywords, built-in function names).

Thanks in advance,
prota

MetaTrader and order book

Ok, I must say the "Ask" and "Bid" predefined variables stores the actually best orders... But what about the other levels and lots of the order book? Can I use these data in my code anyway?

Please help me, I searched a lot everywhere on the web but didnt find the answer.

if (ma[shift] > ma[shift+1])
{
ExtMapBuffer1[shift] = EMPTY_VALUE;
ExtMapBuffer2[shift+1] = ma[shift+1];

}
else if (ma[shift] < ma[shift+1])
{
ExtMapBuffer2[shift] = EMPTY_VALUE;
ExtMapBuffer1[shift+1] = ma[shift+1];
}


IN THIS EA

It's not EA, it's the indicator, which show you moments when "Moving Average" indicator goes up or down.
That code you need calculates last ten bars only.
Put it in /indicators directory and restart your terminal.
