How to write/program EA?

Hi, guys,
How can I start with an EA that works under MT4?
Are there any guides to MT4 programming? What language is needed anyway, is it Visual Basic?
Where can I find them?
Any answer , even saying " read the forum" will be much appreciated

Thanks

Witkot

Here is some information regarding mql4 in general: http://docs.mql4.com/
With this Wizard you can create/learn how to create simple EA's: http://sufx.core.t3-ism.net/ExpertAdvisorBuilder/

hope this helps

Witkot, the links posted by Ronyn are good. There's also other material at the mql4.com site that's helpful, e.g. click on the 'Book' link for an MQL4 primer, and also use the search facility to find answers to questions on specific topics (usually in the 'Articles' or 'Forum').

The language used is more like "C" (the predecessor of C++) than Visual Basic, but with a raft of MT4 chart/indicator/order placement commands thrown in. As long as you have a basic understanding of variables, arrays, loops, if....then.....else, procedures, functions, etc, it's not too difficult to learn.

Thanks a lot, guys.

Hello ! forgive my poor programming skills. I have a strategy where I need the EA to open buy stop and sell stop pending orders immediately. When one pending order is triggered, I will need the EA to open another pending order. all pending orders are to be opened at a specified points. when take profit is hit, I would like the EA to close all orders and start again immediately. How do I put this in the script provided and how do I incorporate the script to mt4? I do not use indicators and so they are to be ignored. I will really appreciate your help.

pls. have a look at http://www.forexfactory.com/showthread.php?t=485460

Hi everyone,

I'm having trouble with a .mq4 indicator I'm programming. I've basically been successful in defining some support and resistance lines based on standard pivot points and can display this on the chart etc, I'm really happy with where the indicator is drawing these level lines.

One thing I'm having difficulty with which I think should be really basic is 'exporting' these price levels as Output Data (price) via a Buffer such as FextMapBuffer 's. When I know I'm successful then it will obviously display the values in the Control+D window.

Without me uploading the entire code can someone please point me in the direction of a help file or tutorial on this? I actually can't believe how difficult its been trying to do this! I'm defining a double for the buffers, SetIndexBuffer(0,FextMapBuffer1); then attempting to use the same formulas I've used to successfully create the DrawLine's to assign the value for the buffers. There's clearly some small piece of code I'm missing OR I'm going about it in totally the wrong way, I'm using various other indicators which display similar Output price data in their code and still can't seem to crack it.

The goal here is for the indicator to communicate with an EA I'm writing so that it can see these levels and use them within the rules for each strategy such as two closes above a resistance level in an uptrend etc.

many thanks guys!
Chris

It's not clear from your post, how you are drawing your lines.
Are you using trendlines/horizontal lines ? If so, you should be able to get the values with ObjectGetValueByShift
or
ObjectGetValueByTime

Im trying to call in this custome indecator ! anyone cold help ?
