Looking for well written EAs and tips for writing same

Hi all,

I've written some pretty handy indicators and the way I got started was to take something already written and make it better.

One of my first was posted here (downloaded >2400 times!):
Here's another two which have much more of my own coding (2 indicators, "P4L Candletime.mq4" and "P4L Clock.mq4", downloaded almost 900 times each):

I guess I'm making the point in advance of my request that I've both received and given back to this great community and shall continue to do so.

Now I'm looking for tips and advice on writing EA's that place trades automatically. There are a zillion EA examples out there, but I would appreciate help from anyone to point me to some of the best written EA's to use as examples.

I have some ideas for developing some buy/sell signals based on a combination of things including RSI, Stochastics, MA's, volume, fibs, etc.

What kinds of "gotchas" should I look out for?

What are the best written routines for reliably placing and closing trades?

What's the best way to manage an open trade, for example, trailing stop, fixed S/L and T/P, ...

How can one do instant alerts (by email or popup) with or without constant repetition or getting duplicate alerts if you change timeframes?

Are there some good how-to-write-EA guides out there?

In your opinion, what are the "best" EA's you've encountered? (This could be in terms of best written, or best in profitability for various kinds of markets, or any other criteria you think it is "best" at).
(I hope to find EA's with mq4 source available, but even an ex4 can teach me what kinds of inputs an EA is asking for).

Do you know of some related threads I should be sure to read ? (Although I have read several maybe I missed a gem).

Thanks in advance for your help, tips and advice.

look on codebase and forex tsd.

Thanks Kenz987. Those are good resources for code but there are plenty of "bad" EA's mixed in with the good, and either way, there are hundreds of possibilities.

I am still looking for people's opinions about which specific EA's are the best written to help me in my search.

Any comments from anyone?

I find Ronald Raygun has good ea's, basicly cause I can work through them and eventually think I know what they are doing.

Coder Guru also lives up to his handle. Often goes over my head, but quality stuff usually from him.

Also lots of methods from Mr Funyoo at his site, both good & so so.

I see the occassional ea coded with generic type functions, so the start() really only sets up the calls to those functions in the required order. Appears to make for more readable code, after you understand those functions. If you learn that technique of coding, Im sure it pays off later.

From a stray site, here's an old Hendrick ea based around functions being called. Bit slow due to being complicated. However sets up the idea.
