I was one of those buyers check out this package he sent this zip file. I thought shoot for $39.99 sounded like a good deal and he was supposedly showing some pretty good fwd. tests, and besides he said he was selling this E.A. so cheap because it was Christmas.The good thing I can say when I complained that this was Pip Boxer E.A. given freely, a few minutes later I was checking my email and found that my money had been refunded.Would like to thank Aparsai for making his E.A. freely available for us to use and I feel there is probably a few sellers on e-bay who are legit, but only a few.

Thanks very much for sharing the information with me and others. I actually found him through your posts on forex-tsd. It seems that he is out of business now (or at least I hope so).

The EA that he was selling is an old version of my EA. It has gone through several updates, so please do not use the attached file. You can use the latest version through the Pip Boxer thread.

Have fun,
Al

I just found out that somebody is selling my EAs (the ones that I've shared with you for FREE) on eBay. He has changed the name of USDCHF Pip Boxer to AutoTrader and sells it under his name.

His eBay user name is currently bg3904. His old user name was merchant409 and he is not a registered user. Beware of this guy.

I was shocked that he has sold the EA for $39.99 to a buyer. The buyer finds out that the EA is a freeware and asks for his money back. He receives his money from the seller immediately.
I just want to update you on this. I received a cheque from this seller today. He claimed that he had sold 4 copies of the EA. He sent me $160.00. I will most probably send the money to a charity. It was a good lesson for me. I'll increase the security of my codes and won't share my source codes with others in the future.

I don't mind if people use or even share my freewares with others. However, I can't tolerate those who sell my stuff under their own names.

Good Luck,
Al

You should go through the links of his previous auctions and check the sold list. It will show you how many he actually sold.

I've seen some of those people have almost 15 sales a day with the forex software.

Thanks for your feedback but I prefer to stop chasing him at the moment. I'll watch his activities closely to make sure it won't happen again.

That EA doesn't generate enough trades for the backtests to be reliable. It should take hundreds of trades to get a reliable backtest. Otherwise, it's simply curve fit.

Sadly, looking through his previous auctions and the other auctions he has listed, he has sold numerous copies of it, and he has a 100% positive feedback. I could just never trust buying something like an EA on ebay, though. Just isn't my cup of tea.

I'm not aware of any methods that can increase the security of the your code. I've heard that people easily decompile MQL compiled files. What I recently do is that I remove the risk management section of my EAs and then compile it and distribute is as demo version. So even if somebody decompiles my EAs par of it is missing.

Al,

I can reproduce your money risk management in a minute without any decompiling. Even though it was probably used for a long time already, it didnt' occur to me up until you pointed it out.

Thanks a lot.

I purchased one system on eBay. It was for Visual Trader and it has proven to be very profitable for me. I believe the seller was only selling it in limited quantities so I'm not sure if it's still available.
Whats the point to sell the ea in limited quantities? if the ea is making money the last thing i would worry about is selling the ea on ebay..........
You sure you not promoting your ebay biz????

Hi
That’s it, decompile MQL is like drink a beer on beach…
MT4 offers no level of security…, even for protects you against a possible “pirate” action from your broker!
In this moment I’m writing my “EA”, in other language to run direct to a data feed, problem is I will have to arrange a “partner” for trust (both parts).

To answer the original question: No, I would never buy an EA from eBay (or anywhere else really). Regardless of how hard it is to make a legitimately profitable EA, it's super easy to code up an EA that's profitable against a specific 2-3 year block of historical data and throw it on eBay. I could turn out two a day easily.

Regarding ex4 decompiling: I've heard that it's doable, but I have no experience in the matter. I can't imagine it's harder than decompiling standard c.

Regarding EA security: Best way I can think of to keep the innards of your EA secret is to write it in a dll and use obfuscated code. The other option which was mentioned was to simply have your EA poll a data source for instructions and just to as it's told. Your call as to whether it's worth it or not.

Selling a money making EA for profit is an oxymoron, if you truly have a profitable EA you can make vastly more money using it than you ever could selling it, therefore in conclusion no profitable EAs are ever sold, quod erat demonstrandum.

Hi Irusoh,

While a professional programmer can develop some sort of Risk Manager, I can assure you the one that I've built is not that easy to build. It considers accounts with different currency of denomination, it calculates the margin calls, and many other features. However, impossible is impossible. The question is does it worth it to spend several hour to develop somehting that you can buy for less than $300.00? Even if it is justifyable for a programmer the average user can't do that.

The last but not the least is that even the muli-billion companies cannot cope with pirate copies of their applicatoins. Who am I to be able to do that? I'm just doing my best to protect myself against such acts as much as possible.

Good Luck,
Al

Let me give you an example. There are companies that are making millions by using a design and drafting package called "AutoCAD". The Autodesk Inc., however, makes millions by developing and selling it. Nobody blames Autodesk. Isn't it weird to blame them for selling it while they could use it themselves and selling it. A successful EA makes money based on your investments. If you have less than 100K investment and an average 5% growth per month your profit with your EA would be less than 5K which by the way doesn't even pay my bills but if you sell the EA you might make over 20K per month. If you were me which way would you choose?

People will never get that they are in forex to make money (in any legitimate way). They treat it as scientific staff, a challenge, something to fulifill their ambitions. Anything but to make money... That's why they treat anyone who sells anything valuable as a scammer.

By posting your software you immediately established a copyright as of that date. If the guy made any money, you have legal claim against him. Either way, you should be able to shut him down for violating your copyright.
Wrong !

Under US copyright laws, once you publish or post something offline or online (like a forex trading system in this case), it automatically becomes "public domain" and you no longer have any copyright privilege.

In other words your work or system now belongs to everybody.

The only way to copyright something, at least in the US, is to actually send it to the Patent, Trademark and Copyright bureau located in Washington, DC and wait for your confirmation letter. Then, and only then, you are legally protected.
