Thread: Info about having an ea made for me

Hi,
I have a few ideas about what I would prefer an ea to do for me.

I'm just wondering if I could find some feedback from everybody.

I will be a bit vague as I'm in work at the instant an can't post everything I would like to (I'll likely edit after more specifics).

How hard would it be for an expert c developer to receive completely aquainted in programming ea's, I understand the language isn't very different? I know this will vary from person to person, however if it's possible to give a rough guess it would be appreciated.

I would enjoy the ea to trade from many differnt indiors, likely about 3, as well as several set conditions for a certain transaction to initiate. A indior or different parameter met would decides each transaction it makes.

I.e. if rsi goes above 70 and then dips back below, THEN sell, and if rsi dips below 30 and then back above, THEN buy.

Or only as an example, if I discovered that prices for x currency pair have a tendency to be rather predictable in a specific time, then it might buy/sell in the time that I specify.

I would also enjoy a selection of money management like a certain proportion of the account per transaction, adjusted lots etc..

I'd also like to make it modular i.e. if I want to just trade 1 element of this ea for some reason i.e. the rsi part I mentioned, it would just trade from those paramaters. Or if I decide that I wish to trade them all, then I should be able to activate all the trade.

And lastly I should be able to alter the maximum number of open positions.

Sorry to ask so much.

How much time should I expect this to take and how much do you think it would cost roughly?

I have seen 2 websites that offer custom ea's however I haven't had a reply from them. Since there are a lot of experts here you are the best people for me to turn to

Thank you

steve

A decent C programmer will have no issue with the syntax (because it's C) but if they do not have familiarity with MetaTrader then I'd be hesitant to hire them. Your specs are fairly broad but nothing mentioned is horribly difficult, the biggest variable will be how powerful you need it.Should it try to account for relationship difficulties and order submission errors (requotes, trade circumstance busy, etc.)? Should it query the server and correct stoploss/takeprofit levels to make sure they are legal based on the broker's stoplevel (minimum allowed space for stoploss and takeprofit values)? Can it account for daylight savings on your time par? Should it error check your diploma to make certain you haven't entered clearly bad values (1000% equity risk, etc.)? I would guess you will get quotes between $50 and $250 for a completed product. The difficult part is figuring out who is offering the very best deal for the price. I would advise that you simply NOT hire anyone who doesn't bother to ask you the kind of questions. If you get an offer check their article history to get an notion of their level of experience.

Wow, that was very good advice, thanks a lot.

I will make sure I include them in my specifiions. Are there some more important things that you or anyone else can think of for me to ask?

I would enjoy it as strong as possible.

1. yes. I really don't know what transaction circumstance is though. How could it take link isues into account? You mean if it disconnects, it looks at all the transactions to make sure they're still inside the parameters?
2. If the stops and take profits aren't legitimate, it may ruin the system so that it's very important.
3. Is this important? I really don't understand what the effects would be? I guess it'd make sense.
4. Yes, I'm human and can readily make a stupid mistake, I would enjoy the ea to detect apparent errors

Can you still believe it'd be about $250 ish?

This may sound like an extremely stupid question, but could it be a very good idea to keep a pc on 24/7 so that the ea can work it's magic constantly, or is that overkill?

When it should be around 24/7, do you believe I should buy a dedied laptop only for metatrader to operate correctly. My disconnects everyonce to acquire a dedied broadband line that is dependable? If this is so, it an optimum broadband speed that I should buy or is standard?


Sorry for all the questions, I just want to make sure I have everything covered

Trade circumstance occupied is an error which may be thrown if you've performed some other order action too recently. If your system can call for reversing orders or opening multiple order concurrently, it is possible to potentially find this mistake (it's much less common than it used to be, a few brokers utilized to need 5 seconds or so between orders). It's just one of several errors a robust system should accommodate.

Depends on the system. If your system is a 24hr a day program, then yes.

MetaTrader isn't overly taxing on a PC or in an online connection. Nevertheless, you need to examine for yourself the risk of disconnects and exactly what it might mean for your system. Some people here use a http://en.wikipedia.org/wiki/Virtual_private_server service in order they can get better uptime.

My recommendations are as followsraw up a record detailing your system and all parameters that you would like to have control over when it's automated. Have the core system coded up, WITHOUT the additional things like parameter and server error handling (and with no money direction ). This will provide you with an EA which it is possible to use for backtesting and forward testing. Then work with a programmer to make it powerful enough to work with on a server Should you decide you need to keep with the system. After step #1, you'll have something to show developers to allow them to quote you a price. If you put some effort into backtests, then you can probably post the doc as well as the backtest results here and get someone to sign up the core system gratis.

After step #2, you'll be in a better position to answer all those other questions you were asking.

I think you should try and build yourself.
Only reason that I say that's I believe that your egy on the rsi will get chewed up.

I would use advice from:
http://www.forex-tsd.com
http://sufx.core.t3-ism.net/ExpertAdvisorBuilder/
forum
and also down heaps from
elcactus.com

good fortune!

Tesla, thanks for your information.

About vps, I own a fantastic few sites, therefore I must have no trouble requesting some sort of solution from my website, thanks a lot

Hi 4xweezal,
thanks for your comments as well as those hyperlinks.
Out of interest, what exactly makes you say about the rsi system? Have you ever done something that did not work out or seen? Or is it gut?

Great information guys, if anyone wants to offer more perls of wisdom then please go right ahead

Steve, why not simply ask Tesla to supply you with a price and have him code it? He's among the best MLQ programmers around...

Hi,
someone just recently made a offer for your job for me.
An undisclosed amount for my full specs and he really seems to understand what he is referring to.

I wont mention his name because he may not appreciate it, if he needs me to then I will

If tesla created an offer then it's quite possible that I would have confessed, but seeing as he (Sorry I don't understand tesla's sex ) didn't make a offer, I presumed that tesla didn't wish to take action.

The job was alloed now so it would be unjust to give it to someone else.

However I might privately contact tesla and cover him/her to give the ea a once over with a second pair of eyes, perhaps he can suggest improvements, developments, changes etc

If produced an offer then it's quite possible that I would have confessed, but seeing as he/she (Sorry I don't know's sex ) did not create an offer, I assumed that did not want to get it done.

The project has been alloed today so it could be unjust to give it to somebody else.

I am a guy.

And that's totally cool, I am remaining extremely busy without additional work.

Feel free to I am me with quick questions and such, I try to make myself available to others.

Cool, when it's finished I may need to shoot a pm your manner
If you think of anything else important that you think should be added, please do post it.

Oh and on the notice of metatrader not causing too much of a drain on the pc. I'm a bit worried about it since I spent a lot of cash on my pc, but im more worried about it being in my bedroom, it can be noisey with it's 6 lovers and I would never get any sleep if I left it on lol.

How can you go about establishing meta trader on a vps? Can you point me? I've looked at the wikipedia however, it didn't explain much with regard to metatrader.

regards
steve
