Good answer but this forum is about low level programming, not about platforms. So in that regard we would prefer either C++ or C# for developing a trading system from scratch.

Yes and if you want to go the other way (C# -> JS), there's a tool for that too: http://projects.nikhilk.net/ScriptSharp

We are a VAR for Barchart, except we are not technically "reselling" anything. We provide free support service and in exchange, we hope that increases sales for our other products. There are many other good data providers out there. We just happen to like Barchart because they are fairly...

Try the Barchart API: www.modulusfe.com/api/ We provide the API at no charge. Barchart.com chares $50/month for the actual data feed service.

Barchart is a good one. They have real time tick-by-tick plus historic data (intraday and end of day). www.modulusfe.com/api/ The price is around $50/mo but that also comes with real time equities. You can also add futures and futures options. Of course there are many other providers such...

We prefer Eclipse, which is widely used, has many plugins and good support.

This forum is about low level programming, not about products like NinjaTrader. Sticky: http://www.elitetrader.com/vb/showthread.php?s=&threadid=227116 Thank you.

Please do not post NinjaTrader questions in this forum thank you. Please see the sticky.

Sure! F# is a programming language.

That'd be fine so long as it strictly relates to the VB code and not Excel.

SQL makes it easy, that's for sure. The speed is sufficient for most applications. But as a software developer, you can of course have fail-over and redundancy built into your application and you should. When you backup an SQL database, you are backing up data to a file (where else)...

If you have a general programming question, feel free to post it here. Examples: Bad question: "How do I submit an order through TradeLink?" (TradeLink has a forum for this) Good question: "How do I use the parallel foreach in C# 4.0 to make my technical indicator run faster"? Bad...

Files are hard to backup? What do you think a RDBS like MySQL or MSSQL use? They use files :)

We're proficient in Assembly, C, C++, C#, F#, Java, VB, FoxPro and just about everything else. Most of us at Modulus have been developing trading software for 15 to 20 years. We do not use nor do we recommend TradeLink or any other trading application. At Modulus, our software is built from...

We can put you in touch with several C# trading system developers. We also offer services starting at $25/hr and up to $55/hr. But if we are too busy to do the work for you, we can certainly refer you to someone. Just drop us an email. Please note this forum is strictly for low level...

That's true. For learning purposes, it's good to stick with Visual Studio or something standard before attempting to write add-ins for a platform.

Yes it is worth it, a hundred thousand times over. This is a real investment in yourself. Learn a real programming language and free yourself from all these platforms. They're designed to keep you hooked. Make sure that you learn using Visual Studio or SharpDev. Don't try to learn...

vikana has a valid point of course. RAM is cheap and you certainly need lots of RAM either way. Personally, I wouldn't want to suggest how much RAM you need, because what I say might be used as a joke in the future, like in the year 2020.

Well, ok but how do you read and write to files with memory alone? :) The OP was strictly talking about databases, not in-memory arrays or such. That's another topic completely. This thread is about databases (such as HDF5).

That's why we use memory mapped files :)
