There are bridges to MT4 in other platforms. They're all based on having an EA running on the MT4, listening to sockets/pipes/etc. A .dll exposes the trading API to the outside world and sends/receives data to the EA. It's not rocket science, just coding drudgery.
Tradelink and Amibroker both suck, I have seriously tried both of these and their limitation is more than you can imagine, especially Tradlink is a completely not even close to complete fun stuff that the creator just tries to force everyone to use his paid mode of tradelink, while even he paid mode is nothing better than the free one.
Someone pm me asking why Tradelink sucks. Here is my tradelink review on page 11: 1. Almost no support. This is basically a dead project, almost no one in the discussion group of official website. There is like 1 message every 10 days or worse. Every message has to be approved and it takes forever. 2. The only guy who is the commerical "glean" guy is the only one answers anything. Most of his answer is "just use glean". Glean is the commercial product that download with tradelink, and you have to pay to unlock. So their plan/his plan is just having no support for open source tradelink, no document, no community even there is one but almost all answers are just "just use glean", then forcing people (well there are almost no people) to pay and use commercial glean with support. 3. As I said, there is no documentation. I have already explained why in point 2. 4. I believe the original goal of tradlink was really few people try to make a true open source trading system, but then somehow it becomes a forcing people to use commercial "glean" trap. Glean itself is extremely poor made and hang all the time, you can try it out then you know. All it does is just asking you to pay. 5. You don't even know what version of virtual studio to use in order to successfully compile stuff. Ask in the official forum? The answer is what you expected: "just use glean!". Check it out if you think I lie. 6. I really doubt the "27,000+ installs worldwide." part. The download count of TradeLinkSuite-3600.exe is just 812 since March 22 (today is May 8), which is extremely not active. Conclusion: This is a good thing to play with and learn if someone wants to build his own system with C#. You have to have good programming skill in order to deal with everything on your own. There are no support and documentation, but the original tradelink (not glean) codes are good places to learn or improve purely by yourself if you are programming expert. It is better than building from scratch if you don't have a full-time trading system developing programming job experience.
The clueless virus is still alive (and still on ignore list of 90% of ET users). "I seriously tried..." Too funny! How would this be possible with just one limited brain cell. I'm talking about a brain cell that is not able to make even the simplest loop possible (proven fact). "No documentation". Eyeless or blind or just limited?
Just click on GeorgeClueney's posts then you can easily tell he is a spammer of Amibroker. It is his job to attack me since I tell the truth of Amibroker, so we need to forgive him and let him have a way to earn his living as a spammer of Amibroker. Good luck GeorgeClueney, I know your life is very hard and you have no choice to choose to career path, we really forgive you but you need to learn how to be a better spammer.
You are wrong again. You are a delusional spammer. I'm the one having more clue than you and correcting your nonsense in regards to tradelink or amibroker or whatever ... You don't tell any truths to whatever there is. Wrong claims resulting from brain limitations are not truths. And for the record again .. I don't have a job at any software firm.. neither at Amibroker nor at Tradelink nor at Tradestation nor at Metastock nor at Microsoft ... nor at Correcting_Wrong_Loops_Of_Disabled_J2ee.yawn.com. You are just a laughable stupid guy I have my fun with.
We understand your situation and you need your post. We know this is a part of your duty but what kind of spammer could I be? A spammer asking people to create their own trading system like this post? http://www.elitetrader.com/vb/showthread.php?s=&threadid=263707 We all know just click on your posts then we know your spammer job, why do you even try to pretend you are not?
