SQLite make C++ and Python to algo trading easier

SQLite make C++ and Python to algo trading easier

I am working on SQLite with C++. I just did it with Python but both programming languages were easy to implement with SQLite. I have out my positions management through callback capabilities from the SQLite APIs done. You still get the benefits of SQL with in memory capabilities. The big drawback is you cannot cluster this over multiple systems but I am sure someone already developed a solution for that.

These techniques have greatly improved my time by reducing the complexity of communication. I hope to demonstrate a complete solution of a C++ process ‘program’ that can manage multiple open positions (market entry) with some basic ‘algo’ to close them. Once the market data conditions are satisfied, an a market exit will take place. All of these are executed through C++ and SQLite callback. More to come in coming days

Redis is fine but the C++ support for a working library on Mac OS  sucks big time

In terms of speed, it might be possible SQLite could outperform since Redis depends on TCPIP. SQLite can be embedded right into the program

Latest of Matlab version will make your trading so much easier!!

Hi there

Last Friday, I posted a few videos that once game again are game changers when it comes to automated trading. As the latest version of Matlab 2012b and 2013a have been released over the last few months, it seems Mathworks has a put a massive effort in extending the M scripting language and prototyping capabilities into the world of professional or instutional traders. I will be focusing on the new techniques in coming weeks so you should join my exclusive QuantLabs.net Premium Membership:

Instead of HPC getting easier , we are now confronted with increasing complexity and a new trend…

Instead of HPC getting easier (as we dreamed of many years ago), we are now confronted with increasing complexity and a new trend…

… emerging almost every year, such as multicore and manycore, scaling up and out, big data, digital manufacturing and the missing middle, green computing, and HPC in the Cloud. For many, especially the end-user, this is a very painful and growing mixture of technical, mental, and even political challenges which no-one is able to handle individually anymore.

HPC is getting crowded

If HPC is moving towards into the cloud there is – at least to me – the question what data is to be calculated there and how to transmit this data into the cloud ?
Is it generated by web accesses on a lot of clients each connected with the cloud data base, or is it locally within the cloud on the HPC system(s) generated, or transferred over local internet connection into the cloud ?

]IMHO, it’s a problem of the right wrapping of really complex technologies. iPod’s story as an example might be annoying, but, well, Apple won because they gave minimal required functionality to their customers, and took away any need to think about formats, codecs, bitrates, tags and that stuff. Since HPC is getting easier, it becomes more and more important to simplify an access to HPC applications (not to clusters or HPC infrastructure or even to set of nodes) for typical everyday users of such apps – engineers, researchers, to anybody else who doesn’t have even imagination about administrative aspects behind HPC applications.

The pendulum swings both ways. In technology that typically includes cycles of new hardware and software, the later always trying to address the failings of the former.

HPC will never get easier in one sense: as the computers become more powerful, the definition of a difficult problem will include previously-considered-impossible problems
